Omega 45.5mm Seamaster Planet Ocean Master Chronometer Chronograph
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 polished black ceramic dial with Arabic numerals, and a date window at the 6 o'clock position. The black ceramic with orange rubber bezel with an Omega diving scale is set on a stainless steel case and comes with a black rubber strap with orange stitching and lining.
The watch is water resistant to 600 meters/2000 feet and has a helium-escape valve. It runs on an Omega calibre 9900 that can be seen through the transparent caseback.
