Omega 43.5mm Seamaster Planet Ocean Master Chronometer GMT
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, a date window at the 3 o'clock position, and a central GMT hand. The world's first polished bi-ceramic black and white bezel with an Omega diving scale is set on a stainless steel case and comes with a black leather strap with rubber lining.
The watch is water resistant to 600 meters/2000 feet and has a helium-escape valve. It runs on an Omega Master Chronometer calibre 8906 that can be seen through the transparent caseback.
