From the brilliant minds of Robert Greubel and Stephen Forsey comes the new Tourbillon 24 Seconds Contemporain Diamonds. For this watch, Greubel Forsey have used a process known as Bienfacture– the art of supreme finishing which transforms rough parts into brilliant jewelry.

This unique timepiece took Greubel Forsey on a journey for bienfacture. They worked with monarchs of the world of precious gemstones to find the finest quality (clarity IF, colour D-E) baguette cut diamonds to enhance the architecture of the watch. These diamonds bring attention to the 24-second tourbillon because the refraction of a perfectly cut diamond directs its play of light.


Because watchmaking standards are higher for precision than the jewelry cut for gemstones, the diamonds set in their timepieces are calibrated within a micron and adjusted like the mechanisms of a timepiece.

The 43.5mm by 16mm in white gold case is also set with baguette diamonds around the bezel and in the lugs. To emphasize the sculptural lines, the stones become part of case structure. The timepiece is set with 272 diamonds totalling 9.71 carats.

For this particular model, Greubel Forsey chose the 24-second tourbillon to be inclined at 25° with a beat of 21,600v/h. The two superimposed, rapid-rotation barrels, have protection against excess tension and deliver a power reserve of 72 hours. They leave space for a large fee-sprung balance and a larger tourbillon cage. The inclined carriage brings the height of the movement to 10.9mm on a diameter of 36.4mm, for 267 components and 40 jewels.

Time Pieces


Greubel Forsey produces some of the most complicated and innovative timepieces in the world. Robert Greubel and Stephen Forsey have much to be proud of at the moment… Because of that we’re giving you a quick tour through some of their beautiful works of art & engineering.


The Double Tourbillon Technique Black

The Double Tourbillon Technique Black is the first Greubel Forsey timepiece to to utilize a titanium case with a rubber band. The steel bridges are highly polished as they add character against the subdued black chrome of the movement plates and other bridges. The Double Tourbillon 30° has 2 tourbillons. One tourbillon rotates inside the other and they are visible at the 6 o’clock position. A transparent sapphire crystal ring indicates the hours and minutes with a miniature second hand at the 9 o’clock position. The watch also has a power reserve indicator at the 3 o’clock position.


The Tourbillon 24 Secondes Contemporain

The Tourbillon 24 Secondes Contemporain is housed in a white gold case. Its signature feature is a “floating” natural titanium movement. The Tourbillong 24 Secondes movement can be seen between 6 & 9 o’clock – it is supported by a transparent sapphire bridge. The dial is mulit-level and features a raised sapphire chapter ring to indicate hours, minutes with the 12 o’clock numerals raised with white gold. The power reserve indicator at 4 o’clock and small seconds at 9 o’clock. Along the caseband at the 3 o’clock and 9 o’clock positions, 2 hand-engraved gold plates rest with the philosophy of Robert Greubel and Stephen Forsey.


The Platinum GMT

The Greubel Forsey Platinum GMT is made with 950 platinum. The dual time zone timepiece displays the global timezones in real time via the North Pole where the time zones meet. The ornate & functional globe is located at the 8 o’clock position where it rotates anti-clockwise to mimic the planet’s rotation over 24 hours. The watch displays the hours & minutes on an off-center dial so that the 24 second tourbillon can still be seen at the 5 o’clock position. The small seconds are indicated at 2 o’clock position on the dial with a sectorial power reserve placed at the 3 o’clock position, and finally the second timezone at the 10 o’clock position. The timepiece’s case back is utilized to display the universal time for 24 time zones through the use of a rotating disk that shows the names of 24 cities around the world! The watch even delineates through lightly colored cartouches to differentiate summer time.


The Double Tourbillon Asymétrique 

Greubel Forsey’s Double Tourbillon Asymétrique, housed in a 5N white gold case, is a unique and modern vision of the Double Tourbillon 30°. The timepiece was produced a limited edition of only 11 pieces with the 5N white gold. Another 11 pieces were produced in white gold. The timepiece utilizes an asymmetric case. The Tourbillon Asymmétrique features a curved lateral window showcasing the double tourbillon system at 8 o’clock position with a disk indicating the power reserve at 2 o’clock that utilizes a fixed red triangle. The dial is made black from anthracite and features white gold hour, minute, and small second hands.


Greubel Forsey recently introduced the Platinum GMT… The watch is yet another stunning creation from the brilliant and technical minds of Robert Greubel & Stephen Forsey. With the Greubel Forsey Platinum GMT, they have created a unique method that allows them to view world time through 3-D rotating globe. The watch also features a second timezone indicator and an inclined tourbillon.


The movement is housed within a 43.5mm platinum case with a window allowing one a stunning view of the globe, tourbillon, power reserve, and second timezone indicator… It comes together in only the way Greubel Forsey can make it do so. The Platinum GMT’s back shows a world time ring listing the world’s major cities – 24 timezones – as well as a gold sun to indicate the noon position.


The watch uses the GF05 movement from the GMT series that shows hours, minutes, small seconds, power reserve indicator, and day/night indicator on the dial. The watch also has all time zones accessible via the GMT on the watch’s side.

The watch comes in Platinum, 18K white gold, 18K rose gold and is fitted with an alligator leather strap with stitching and a matching buckle.

Oftentimes life is complicated… And oftentimes, those complications are not wanted! In the world of fine haute horlogerie, the opposite is true. Patek Philippe has released the most complicated watch they have ever produced. The 174 year old watch brand is truly the master of fine watch complications.

The $1.3 million watch is the Patek Philippe Ref. 6002 Sky Moon Tourbillon. The timepiece has 12 complications making it a “Grand Complication.” The watch has a tourbillon, minute repeater, sky chart, and a perpetual calendar. The sky chart on the back of the timepiece shows its wearer the evening sky in whatever region of the world they reside. The moon-phase then shows whether the moon is a crescent or full moon.

This watch took 7 years of development to make with the engraving taking more than 100 hours. The minute repeater chimes a note that is tuned to sound like cathedral bills. The price for this watch comes to $1.3 million, but that does not necessarily mean there is one available…

One must apply for ownership of the Patek Philippe Ref. 6002 as it is a Patek Philippe “application piece.” The fine watchmaking brand does what it can in order to ensure that those who end up owning a Patek Philippe 6002 are owners who will truly appreciate the fine timepiece. They must ensure that Ref. 6002 owners have a proven track record with Patek Philippe and that they will truly appreciate this stunning example of haute horlogerie. Patek Philippe has made it very clear of their intentions, “Even if you offered $6 million for the watch, we wouldn’t sell it to you unless you’re approved,” said Larry Pettinelli, president of Patek North America.

No one is sure how many Patek Philippe Ref. 6002 Sky Moon Tourbillons will be made, but Larry Pettinelli has said “it will be very few.”

Founded more than 170 years ago, Patek Philippe’s watchmakers have continued to demonstrate their expertise and attention to detail. They have expanded their impressive list of complications and delivered what is undoubtedly the finest of timepieces in the World.

A perfect example of this history & expertise is Calibre 89 that was unveiled in 1989. The 33 complication piece holds the record as the most complicated portable mechanical timepiece ever created. The Patek Philippe Sky Moon Tourbillon, or Patek Philippe 5002, is the brand’s most complicated timepiece. It has 12 complications on 2 dials and now with the Patek Philippe 6002, that design has been fully refined. The Patek Philippe Sky Moon Tourbillon, or Patek Philippe Ref. 6002, redefines the Grande Complication. We hope you enjoy this video of the stunning piece.

In today’s world every thing around us is run by electronics… Ironically, the one item that for many of us is not run this way can be easily effected by the other’s presence. The watch on your wrist is on you all day and the steel components of the mechanism can be very sensitive to a magnetic field. The way they function and their accuracy can be greatly disturbed or altered by the electricity and magnetic fields household and other items produce.

Here are some items many of us are surrounded by daily that can have an impact on the performance of our watches.

–  mobile phones
–  laptop computers
–  microwaves
–  hair dryers
–  television sets
–  refrigerators
–  handbag, wallets, purses, and other items with magnetic closures
–  speakers
–  and more!

The Rolex Milgauss (shown below) was originally designed for doctors who are surrounded by more magnetic fields than most of us during their daily lives at a hospital. The Rolex Milgauss was built to better stand up to these magnetic fields & resist being magnetized.

This item list goes on & on… The magnetic fields have 3 main effects on a watch depending on how intense they are…
1) They run slightly fast when the magnetic field is very low intensity.
2) If the magnetic field is of medium intensity, the watch’s mechanism will become magnetized and this will, in turn, affect how its components interact with each other. This will remain until the watch is demagnetized.
3) If a watch is in the presence of a magnetic field too large, it will completely stop.

Whatever intensity of magnetism the timepiece is exposed to, the regulation and amplitude of the movement will return to normal after demagnetizing it. This intervention has no consequence on the timepiece but it must be completed by an Authorized Service Center. deBoulle Diamond & Jewelry is an authorized service center for many fine brands such as Patek Philippe, Tudor, Rolex, Breguet, Jaeger-LeCoultre, and more…

The Rolex Daytona is one of the most well-known timepieces made under the Rolex brand. The watch is the epitome of Rolex’s focus on precision and competition.



The watch has evolved since it’s inception 50 years ago, yet it remains a style icon. The Rolex Daytona is extraordinarily desirable – as many of our readers already know. Largely unchanged over the years, the watch has seen only very small variations; such as a new platinum version with a blue dial.



Rolex has chosen to keep the timepiece’s 50 year anniversary fairly relaxed as the Daytona Cosmograph has always progressed. The watch is tied to the history of motorsports and so this progression and pursuit of excellence go hand-in-hand. There is no other product as aligned to or as closely linked with a single sport.

The Values of Rolex
The full name of the Daytona timepiece is the Rolex Oyster Perpetual Cosmograph Daytona. Rolex has more than 9,000 employees that work in places such as Geneva, Biel, as well as Rolex subsidiary offices — including Dallas, TX. Rolex understands the history and philosophy that has made them so successful, and so they have been always been able to move forward. To fully understand Rolex often requires noting what has been left out or not said and that includes the Daytona. From the outside, we can praise the timepiece’s precision, beauty, elegance, reliability, and strength. The Daytona does more than that though as it embodies all of the Rolex brand’s ideals and strengths. Very few companies, if any, have ever been able to produce a piece that so perfectly captures the spirit and values behind their success. This ability is what makes Rolex and the Daytona so special.

Originally, the Oyster Perpetual Cosmograph Daytona was not “The Daytona.” The city of Daytona Beach, Florida who lent its name to the iconic timepiece is known for hosting land speed records on their beautiful stretch of beaches since 1903. Later, the legendary speedway was added to the area and further increased people’s awareness of the racing taking place there. The Rolex Cosmograph debuted in 1963 as a new generation of chronograph aimed at racing drivers. The watch had contrasting subdials on the main dial. The tachymeter scale , placed around the bezel, allowed the wearer to calculate the average speed over a given distance. This became a significant part of the watch’s design. After this, the timepiece went through several changes. For example, in 1965 the chronograph pump jumpers were replaced with screw-down pushers. A later adjustment to the watch was the plexiglass fitting with white marks on the tachymeter bezel.



Small Changes Over Time
Around 1965, the Daytona signature began being used on certain dials in the Cosmograph range. The marking was initially reserved for watches sold within the US markets as it was originally requested by Rolex’s American subsidiary to better show the partnership between Rolex and the Daytona International Speedway. This partnership highlighted the link between the Daytona and the motorsport world. Eventually, the Daytona signature was placed on all dials of the Cosmograph with red letters above the subdial at the 6 o’clock position.

After the 1960s-1970s when (the quartz revolution), Rolex remained loyal to the automatic movement within the Cosmograph Daytona, which in 1988 held a self-winding movement. The movement was commercially available, but Rolex made extensive adjustments and modifications that replaced more than half of the original components with its own parts. These changes brought the movement in-line with Rolex’s own high standards and specifications.

The resulting movement was called the 4030 calibre and featured the Rolex “heart” — an oscillator with variable inertia balance, Microstella regulating pins, and a hairspring with Breguet overcoil, completed by the Perpetual rotor which Rolex developed in 1931. Changes were pushed farther than just the movement within the watch as the diameter of the Oyster case was increased from 36mm to 40mm and the crown-guard shoulders were also added later. The metal tachymeter bezel was also made wider and engraved with a scale graduated to 400 units.


Continued Innovations & Development
The watch received an upgraded and new self-winding chronograph calibre in 2000. This time it was entirely designed & engineered by Rolex — the calibre 4130. The new movement featured a vertical clutch to activate the chronograph functions. Rolex’s engineers cut the number of parts by roughly 60% by simplifying the chronograph hour and minute counter systems. They also integrated the 2 mechanisms into a single module.

The innovations produced not only gave the engineers & designers more space and so they were able to increase the barrel size and provide wearers with 72 hours power reserve — up from 50 hours. The modern Cosmograph Daytona movement utilizes a Parachrom hairspring. The spring is now developed, patented, and manufactured by Rolex in a niobrium/zirconium alloy. It is unaffected by magnetic fields and variations in temperature that could upset other timepieces. It is also more resistant to shocks, so the timepiece’s precision has been greatly increased.



Rolex has promised to continue its passion and development. The brand will be rolling out continued innovations over the many years yet to come.

Known for their innovative and stunning multi-tourbillon watches, Robert Greubel and Stephen Forsey of Greubel Forsey have not rested. They recently teamed up with artist Willard Wigan to create the Greubel Forsey Art Piece 1- the GF AP1. The timepiece has a 30 degree dual tourbillon, and it features a Wigan microsculpture that the wearer is able to admire through a magnifier in a special crown.

Willard Wigan is a British artist and although he may not be well known to those outside of the art world, those “in the know” regard him as a legend. Fun fact, he was knighted by Prince Charles in 2007. Wigan has been making sculptures the size of a needle’s head with some even smaller than red blood cells. Wigan constructs his pieces utilizing tools smaller than shards of diamonds and other gemstones. One of these micro-works-of-art rests inside the GF AP1.

The watch is completed by Greubel Forsey’s signature 30 degree double tourbillon. The cage, tilted at 30 degrees, rotates one time every minute while the outer cage sits parallel with the dial and completes one rotation every 4 minutes. The watch has a huge curved bridge that holds the double tourbillon between sapphire crystal and its caseback. One sees straight through it because of its crystal construction.

The dial has a beautiful blue tone and the mainplate is engraved with names of the three artists, watchmakers, and innovators involved: Stephen Forsey, Robert Greubel, and Willard Wigan. There is a 72-hour power reserve indicator at the 4 o’clock position – this is the only indicator you will find anywhere on the GF AP1. At 3 o’clock the crown is used only to wind the tourbillon.

Looking through the magnifier, that is styled like a second crown at the 9 o’clock position, one views the magnificent work of Willard Wigan. A dark blue bridge supports what looks like a simple spot of gold from the dial-side. At 23X magnificiation, the simple spot of gold becomes much more. You see that Wigan’s amazing sculpture is crisp & clean cut. The 3 mast sail boat appears to sail across the blue support with an all open-working bringing through enough light to view it perfectly.

Very few of the Greubel Forsey Art Piece 1 have been made with each containing a unique microsculpture from Willard Wigan. The “Golden Sails” edition is for sale at just under $2 million, but official pricing is available upon request. Take a look at our photos and let us know if you have any questions that you would like answered about Greubel Forsey timepieces or the GF AP1 specifically. deBoulle is proud to carry Greubel Forsey. Check out the latest from Greubel Forsey.

It is water resistant to 150meters & utilizes a sapphire crystal. The watch also features a bidirectional rotatable 12-hour graduated steel bezel for dual time-zone display via a blue disc.


The movement is the Swiss automatic Tudo caliber 2892 (base ETA) with chronograph module. The timepiece has a power reserve of 42 hours as well as a 45-minute totalizer at the 9 o’clock position, small seconds hand at the 3 o’clock position, and date at 6 o’clock position.

The watch comes with interchangeable bracelet options — a steel bracelet with folding clasp & safety catch as well as a fabric strap with buckle.

F.P.Journe combines a rich knowledge of the history of time with the example set by the great masters and modern technologies, in an ongoing quest for precision, innovation and excellence. The watches they produce are truly timeless and represent the pinnacle of watchmaking technology.

The Chronomètre Optimum encompasses the finest components in the history of watch making. All of them will be reunited for the first time in a single magnificent timepiece. The extraordinary technical expertise that has gone into this watch makes its principal quality to give time … with almost as close to absolute precision as one could ask.

– The double barrel has two springs in order to ensure stability of the driving force of this emblematic movement. It is made with 18ct rose Gold, a specificity of the brand.

– The constant-force remontoire (patent EP1528443.A1) balances the driving force applied to the escapement to make it constant. By adding an extra gear representing an independent system wound in short spurts by the mainspring, the escapement ensures the balance’s isochronism. This remontoire, made of titanium for the first time, maintains its balance in different positions, for greater efficiency.

– The EBHP High-Performance Bi-axial Escapement has also been patented (patent EP11405210.3). This two-wheel direct impulse escapement functions without oil and is the only direct impulse escapement to start up on its own. But not only does it function without lubricant, it also has far greater output than the majority of escapements: 50 hours without loss of amplitude.

– The balance with a spiral with Phillips curve guarantees better stability.

– The back of the 18ct rose Gold movement reveals, a surprising natural dead beat second defined by a seconds circle screwed onto the movement’s bridges.

The Chronomètre Optimum comes with a 40 or 42 mm Platinum or 18ct red Gold case, with a white or red Gold dial, on leather strap, Platinum or 18ct red Gold bracelet. Exceptional timekeeper, the Chronomètre Optimum joins the iconic timepieces and complications of Haute Horlogerie.
