Who’s on Watch

Time Lag

Brought into effect in 1929, it separated the globe into 24-hour zones, with each one corresponding to 15° of longitude. It encouraged watchmakers to produce timepieces with two different times being displayed at the same time. As the Greenwich Observatory in England was fixed as the zero meridian, it gave its name to the GMT timekeeping function: Greenwich Mean Time. This little mechanical complication is usually overcome with a central hand with a triangular point indicating another time zone on the 24-hour clock. These models which are aimed primarily at globetrotters are among the manufacturers’ classic designs, some of which can show GMT in a counter, in a small window or on a rotating disk


Esprit pilote


Bell & Ross have always been inspired by aviation, and now they are offering this stainless-steel BR V2-93 GMT 24H with either a metal or rubber strap. The notched, two-tone bezel (with a day/night indicator) is bidirectional, meaning that you can easily change the time of the second time zone that is displayed by the orange hand.


Slimline Record


Bvlgari can claim a new world record when it comes to slimline design with the titanium Octo Finissimo Chronographe GMT Automatic, with a maximum thickness of just 6.9mm (1/4”). The casing has a button at 9 o’clock, allowing you to intuitively adjust the additional time zone (there is a 24-hour counter on the right).


Bronze Beauty


The Pilot’s Watch collection has always been the most emblematic at IWC, and they have now enlarged their range with the bronze Spitfire UTC (Coordinated Universal Time). It’s a material which ages over time, giving each watch a unique patina. Here, the second time zone is shown in an arched window below 12 o’clock.


Indispensable Travel Accessory


Travelling has always been one of Louis Vuitton’s favorite themes, and it appears again in this steel Tambour Moon GMT watch. Decorated with a grain of rice motif, the dial has a small hand with the yellow end forming a V which indicates the added time zone (also yellow) using the 24-hour clock.


The Height of Vintage


Montblanc’s Heritage range features pure vintage watches which hark back to the Minerva watches of the 40’s and 50’s. This steel edition has a fine, blue GMT hand using the 24-hour clock and a remarkably supple Milanese Mesh strap.


The Rapture of the Deep


With its orange-pointed GMT hand, Omega’s ceramic Seamaster Planet Ocean 600M GMT is an exceptional diving instrument: waterproof down to 600 meters (1,970 feet), a unidirectional rotating bezel, a helium valve and luminous elements. It is also equipped with an antimagnetic Master Chronometer caliber.


An Icon on your Wrist


Always loyal to the original watch which was created in 1955 for the pilots of the American airline Pan Am, the GMT-Master II is one of Rolex’s most emblematic models. Waterproof to 100 meters (330 feet), there is a blue hand which indicates the second time zone, and on the two-tone rotating ceramic bezel (with a day/night indicator), there is also a Superlative Chronometer certification, a byword for exceptionally high performance.
