Of course, the real story here is on the inside of the watch, where we find Omega’s Caliber 8900, the first “Master Chronometer” movement, so named because it meets both the official chronometer standards of the Swiss testing agency COSC, but also the criteria set forth by Omega’s own METAS certification. To be specific, these are the the eight criteria measured by the latter process:
• The movement function during exposure to a magnetic field of 15,000 gauss
• The deviation of the watch’s running time in six positions
• The deviation of the watch’s running time between 0 and 2/3 of its power reserve
• The watch’s function during exposure to a magnetic field of 15,000 gauss
• The deviation of the watch’s average daily precision after exposure to a magnetic field of 15,000 gauss
• The watch’s average daily precision in tests replicating daily wearing conditions (six positions, two temperatures)
• The watch’s power reserve (autonomy – functioning without winding)
• The watch’s water resistance (tested in water)
Ultimately, the watch is required to perform within a tolerance of 0 to +5 seconds per day during and after exposure to the 15,000 gauss magnetic field to receive the Master Chronometer designation.
A final aesthetic touch, which pays tribute Omega’s history of high-precision timepieces, is found on the gold medallion set into the Globemaster’s sapphire exhibition caseback, which features an engraving of an observatory’s cupola — a reference to the site where the famed chronometry tests of the 1940s and ’50s took place — surrounded by a sky dotted with eight stars. The stars serve the dual purpose of referencing both the most important eight of those chronometry awards won by Omega throughout its history and the eight Master Chronometer criteria. Best of all, since the medallion doesn’t cover the entire caseback, the wearer still gets a view of Caliber 8900/8901 and its swinging Sedna gold rotor.
Omega unveiled the movement and the watch at an event at Basel’s Von Bartha gallery this week during the Baselworld watch fair. Here are a few live shots of the Omega Globemaster taken at the event.
