Today is known to some as “Leap Day” and to others as “Perpetual Calendar Day!” In honor of “Perpetual Calendar Day,” a complication seen in several timepieces at de Boulle, let’s take a look back at this fascinating piece of horlogerie.

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.

Jaegar-Lecoultre was by no means disappointing at the Salon International de la Haute Horlogerie in Geneva , but after months of anticipation, potential clients were left wanting more. There were rumours of a completely new collection, but the watches were no where in sight.

However, it was all worth the wait! Jaegar-Lecoultre introduced the Hybris Artistica Collection. The collection includes 12 watches and they are all spectacular! Each model represents an unprecedented blend of design, technical construction, watchmaking art and exquisite craftsmanship to achieve the point of equilibrium that dramatically expresses the Manufacture’s mastery and style.

Here are a couple of the models from the Hybris Artistica Collection:

Master Grande Tradition Gyrotourbillon 3



Master Grande Tradition Tourbillon Celeste



These are only 2 of the 12 models in the Hybris Artistica Collection. They are all amazing, so check them out today!

Jaeger-LeCoultre and Polo (the Sport) Continue!


2013 is the 180th anniversary of Jaeger-LeCoultre. Because of this, the Manufacture unveils the Grande Reverso Ultra Thin Duoface to celebrate the very essence of their timepieces. The classic watch comes with the swiveling case. The swiveling case is part of a new, even slimmer design that captures the function appearing on their iconic design. Jaeger-LeCoutre even squeezes a dual time-zone display into the watch. The watch’s design is a display of the exceptional partnership between the Manufacture Jaeger-LeCoultre and the venerable “Casa Fagliano” in Buenos Aires where the Reverso reconnects with its sporting heritage. This is yet another mark of Jaeger-LeCoultre on the polo world.

During the 1930’s polo players often shattered the glasses of their timepieces during the intense moments of their sport. A year after this, polo players began wearing the first watch in history to have a swiveling movement that allowed players to protect the face of their valuable timepieces. To add to this, the watches also allowed them to display their monogram or family crest. These works of art have advanced over the years, but their heritage has remained in tact. The watch has been made into both men’s and women’s versions as well as in varying degrees of technical forms.



This year the watch manufacture celebrates its 180th anniversary by unveiling the Grande Reverso Ultra Thin Duoface Blue which combines style with the genius watchmaking ability Jaeger-LeCoultre. It has a second time zone on its back while the front dial remains dedicated to local time. The unique watch comes with blue-lacquered dial that picks up the exact shade of the color that is on the original model. It also features rhodiumed dagger-type hands and baton-type hour-markers. The top of the dial has the REVERSO inscribed in the EXACT font of the original watch from 1931 polo matches. The Grande Reverso Ultra Thin Duoface Blue will be fitted with an especially rare and distinctive strap. Made from extremely refined cordovan leather, it comes from a craft workshop which, like the Grande Maison in the Vallée de Joux, is still located in the exact same spot where it was established in the 19th century.

Created in 1883, Jaeger LeCoultre has a history of innovation, art, and design. Watch the video below for a visual representation of the history & innovation of Jaeger LeCoultre watches. For more information regarding Jaeger LeCoultre contact the experts at deBoulle Diamond & Jewelry.

One of deBoulle Diamond & Jewelry’s most sought after brands of fine timepieces is Jaeger-LeCoultre. Jaeger-LeCoultre has continued to advance and improve their products since their inception.
“After 10 years of non-stop innovation in the world of the tourbillion, what is there still left to invent? Which new additional functions could further complete the tourbillon of the future? Jaeger-LeCoultre presents the new Duomètre à Sphérotourbillon, the first watch with a multi-axis tourbillon to give an accuracy that will display the time with extreme precision, thanks to a small seconds hand equipped with a flying set return which enables the Jaeger-LeCoultre watch to be adjusted to a precise instance of time. The Duomètre à Sphérotourbillon is today an authentic revolution in the field of Grande Complication models, stemming from almost 180 years of history and invention unique to Jaeger-LeCoultre.”

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.
