Omega 43.5mm Seamaster Planet Ocean Master Chronometer
Omega introduced the Planet Ocean line in 2005. It pays tribute to Omega's dive watch heritage.
This watch features a scratch-resistant sapphire crystal, a black ceramic dial with Arabic numerals, and a date window at the 3 o'clock position. The black ceramic bezel with an Omega diving scale is set on a stainless steel case and comes with a stainless steel bracelet.
The watch is water resistant to 600 meters/2000 feet and has a helium-escape valve. It runs on an Omega calibre 8900 that can be seen through the transparent caseback.
