Omega Men's 2535.80.00 Seamaster 300M GMT "James Bond" Automatic Chronometer Watch

 Set a course for adventure with this classic Omega Seamaster stainless steel men's automatic chronometer watch, part of Omega's James Bond collection. You'll be able to negotiate all manner of adventures and still look stylish in the boardroom or at the baccarat table. This highly accurate, self-winding timepiece--which features Omega's break-through the Co-Axial escapement--is also a great diving watch, with water resistance to 300 meters (984 feet) and a helium escape valve, which allows helium to escape from inside the watch when the watch is worn in highly pressurized environments (such as long-term underwater work or crude oil exploration). Definitively masculine in design, it features a large, round silver stainless steel watch case with a rhodium-plated finish that blends brushed and polished surfaces and measures 41mm wide and 11.5mm deep.

It's topped by a durable aluminum unidirectional bezel in blue with silver markings, which frames a blue dial background with luminous hands and dotted dial markers, as well as a window at 3 o'clock for the automatic date display. Other features include screw-in caseback, screw-locked crown, and scratch-resistant and glare-proofed domed sapphire crystal. It's completed by a silver stainless steel link bracelet band that offers polished highlights, which is joined by a secure, push-button clasp.

Originally created in the 1750s, the first chronometers were clocks that were accurate enough to calculate the longitude of a ship's position. Today, the chronometer label is bestowed upon timepieces that have undergone precision tests and received a certificate from the official COSC (Control Officile Suisse de Chronometers) regulatory organization that rigorously tests and certifies (or fails) watch movements for chronometer status.
