Horology is the science of time, timekeeping, and timekeepers. Knowing how to wind and set your watch is important for anyone interested in this science.

A timepiece can be a big investment, so it is imperative that you know how to keep them in top condition. It’s always a good time for a primer on setting and winding a watch—whether the timepiece is powered by a battery, requires near-daily winding, or winds itself when worn on the wrist.

Check out this informative video from David Lee, the Vice President of Certified Pre-Owned at Tourneau, as he offers an easy-to-understand guide to the fundamentals of horology: How To Wind and Set Your Watch

We hope this helps you understand how to keep your timepiece in great working condition!

Sometimes, less is more. That  seems to be the current trend in the higher echelons of horology.

Despite the world being enthralled by technological advances, the finest watchmakers stick to relatively simple designs. They believe that their costumers are not looking to be flashy. The US President of Patek Philippe, Larry Pettinelli, says “Our customers aren’t usually trying to show the world that they’ve made it, most people don’t recognize our watches from 10 feet away unless they’re collectors.”

Here are some examples of Patek Philippe’s latest timepieces:



These pieces are beautiful and amazingly built– everything you have come to expect from Patek. They are not over the top  and people enjoy that. Even complicated-watch fans are starting to acknowledge the absurdity of certain gizmos.

It seems that simple is the new way to go.


Celebrating the 10 Years Anniversary Tourbillon, F.P. Journe presents an exclusive series that is limited to only 10 pieces. Such a combination of numbers could not go unnoticed, combining the 10th Anniversary of the first F.P. Journe Boutique in Tokyo, jointly with the inauguration of the 10th Boutique in Beirut.

In 2003, the first F.P. Journe Boutique of Tokyo opened. It is located in Omotesando, the St Germain des Prés of Tokyo, and is settled in one of the most beautiful architectural realisation of spirituality by Tadao Ando. The boutique has become a place of reference for the admirer of contemporary chronometry, as well as all other F.P. Journe Boutiques around the world.

François-Paul Journe proposed a unique solution for the delegation of these 10 exclusive timepieces: ‘Our ten Boutiques have each proposed us candidates among our faithful collectors. Their name will be randomly selected by draw during our annual fair in January 2014.’

Celebrating the 10th Anniversary of the First F.P. Journe Boutique, the Anniversary Tourbillon in Platinum presents an identical movement to the original Tourbillon of 1983, but is manufactured with 18kt rose gold which is visible through the sapphire display back. The dial is in grained in silver with a blackened hour display that is even rarer than the dial of the Black Label edition reserved for the Boutique. It is maintained by a screwed steel polished circle. The hours are indicated by the classic Breguet hands.

The platinum case measures 40mm x 9.5mm and has double sapphire crystals.

The movement is the Swiss manual-wind F.P. Journe in-house caliber 1412 with 19 jewels, 21,600 v/h and a power reserve of 56 hours. It has a grained base plate of 18kt rose gold with grained bridges of 18kt rose gold.

The escapement has 15 teeth, a 90° anchor fork and a balance that comes with 4 inertia weights. Some of the features include: a flat Anachron balance spring with Breguet overcoil, fixed stud holder that is free-sprung with a spring pinned to collet, a pinned GE stud, and 2 parallel barrels. The screw heads are polished and beveled with chamfered slots, blued screws, and pegs with polished and rounded ends.

The dial is grained in silver with the hours displayed in blackened engraved silver that is fixed by a steel polished circle (patented system) with white steel Breguet hands.

The Breguet Reine de Naples Day/Night ladies timepiece will feature a new patented automatic movement. It has a unique indication on two dials with one showing the traditional hours & minutes and the other showing the hours of day and night… The timepiece is accented with brilliant blue on the complications within its face as well as a stunning diamond bezel.

The timepiece features a disc of lapis lazuli for the sky, the clouds are made with mother of pearl, gold represents the stars, and engraved platinum shows the moon. The sun is symbollized by the facetted rim of the watch’s balance wheel.

The balance moves through the day and so the sun makes a tour each day as it passes beneath the steel bridge that supports the mechanism and meets the hands for hours and minutesas it reaches its zenith facing the onlooking engraved titanium moon!

Fine timepieces from the likes of like Patek Philippe, Breguet, Blancpain, and Girard-Perregaux have evolved greatly over time. One such complication that came into being because of this technological evolution is the minute repeater. This grande complication allows one wearing wristwatches with the complication to make the timepiece chime the time. One can then not only see the time, but can also hear it played musically! This is all accomplished through a purely mechanical design and because of this it has been dubbed as the most extraordinary grande complication of fine timepieces. The engineering and complexity involved within such a timepiece make the minute repeater a brilliant demonstration of a watchmaker’s skill level and expertise.

Below are some of the most talked about minute repeater watches from brands like Patek Philippe, Breguet, and Girard-Perregaux. deBoulle Diamond & Jewelry is an authorized dealer of each of the watches shown in the photos below.

Determining how a watch company got its name is pretty straight forward, they are usually named after the founders.  Breguet, Abraham-Louis Breguet.  Patek Philippe, Norbert Patek founded his watch company and later hired Adrien Philippe.  Jaeger-leCoultre, Edmond Jaeger joined forces with the company Antoine LeCoultre founded 80 years prior.  Girard-Perregaux, Constant Girard married Marie Perregaux and took charge of her family’s manufacturer.

Some are a bit tricker.  TAG Heuer began as Heuer Watch Mfg in 1860 and in 1985 the French firm Techniques d’Avant Garde bought them.  Viola!, TAG Heuer.  Bell & Ross, Bruno Belamich and Carlos Rosillo.  Bell & Ross not only is easier to say but it fits on the dial much better.  Hublot is an Italian word for porthole.  Bonus points if you can get Maurice Lacroix.  He was on the board of the Swiss firm Desco when they changed their watch manufacture from private label to a branded watch.

Some incorporate the region of the manufacturer.  IWC Schaffhausen is located in Schaffhausen Switzerland, north of Zurich.  Glashütte Original is in Glushutte in the Saxony region of Germany.  Lange & Sohne is located there as well, named after Ferdinand Lange of course.

And then there’s Rolex.  Hans Wilsdorf started his watch company in London in 1905.  Perhaps the name Wilsdorf was difficult to pronounce or like B&R didn’t fit the dial well.  Whatever the reason, he registered the trademark Rolex in 1908 and a brand was born.  There is much conjecture behind the name including the odd one that Rolex is the sound made when the watch is wound…hmmm.  James Dowling of TimeZone claims that Rolex was simply made up.  This falls neatly into the theory of the simplest explanation is usually the correct one.  Wherever the name came from, Rolex isn’t talking which makes it all speculation.  But that’s usually the fun part.

In recent years, we have noticed a tremendous spike in the prices of precious metals. Gold hitting a record high over $1,800 an ounce created a feeding frenzy of epic proportions and nearly everyone from pawn shops to jewelry repair centers got in on the action by seeking “scrap” gold. Diamonds as well hit a peak in late 2008, subsequently fell down, and have since risen back from out of the ashes. There is however, one investment that has stood the test of market peaks and valleys…high grade watches.


When one hears the term “high grade” in relation to watches, many different brands may come to mind…probably the most common being Rolex. While the vintage Rolex market has indeed remained strong, one brand stands out above all the rest: Patek Philippe. If you look to see what watches have set record highs in auctions such as Christie’s, Sotheby’s, and Antiquorum again one name stands out: Patek Philippe watches.

It is common for Patek Philippe watches to fetch well over a million dollars at auction. In November of 1999, a yelow gold split seconds chronograph from the 1920s brought an astonishing $1.92 million which was the highest price ever paid at an auction for a wristwatch and it was Patek Philippe. As another example, a steel Patek Philippe perpetual chronograph (ref. 1518) which retailed for CHF 2,465 in 1948, realized a price of $814,490 at auction in October of 2000. Patek Philippe is one of Geneva’s oldest watch companies being founded in the 1800s and is still run today by the 3rd and 4th generation of the Stern family. With over 70 patents to it’s credit; Patek Philippe designs, produces, and assembles what many experts agree to be the finest watches in the world.

None of this has escaped the attention of collectors and connoisseurs the world over. Patek Philippe watches are by far the most in demand watches there are and hence have become a very sound investment. Some series from Patek Philippe like Patek Philippe Annual Calendar, Patek Philippe Perpetual Calendar and Patek Philippe Calatrava have become a synonym of class and luxury and are sought after by prominent personalities around the world. People who visit deBoulle are often shocked by the value that their watches hold over the years. It is always a delight to be able to tell someone that their treasured timepiece has appreciated, especially some which are not even a few years old. I would encourage all of those looking to make a sound investment to consider Patek Philippe watches, for unlike precious metals, stock, and bonds…this is an investment that you can enjoy daily and pass along to the next generation to enjoy for years to come.
