Inspired by OMEGA’s maritime legacy, the Seamaster Planet Ocean was launched in 2005. Today, the collection continues to pay homage to the brand’s dive watch heritage, with updated style and advanced precision.

For this chronograph model, the 45.50 mm case is crafted in brushed stainless steel and features pushers with brushed black ceramic rings. There is also a brushed black ceramic bezel ring with its diving scale in Liquidmetal™.

The dial is presented with a sand-blasted “gunmetal” grey galvanic treatment and includes a date window at 6 o’clock, sandblasted stainless steel subdials, along with transferred words in beige and white. The OMEGA logo, Arabic numerals, hands, and hour markers are all in PVD stainless steel with a brushed finish, while the beige Super-LumiNova improves visibility in dark conditions.

Powered by the Co-Axial Master Chronometer Calibre 9900, this Seamaster Planet Ocean is worn on an integrated dark grey rubber strap with a structured pattern and beige and dark grey stitching. The NAIAD LOCK caseback is completed with a metallized seahorse on the sapphire crystal.

**To achieve Master Chronometer status, it has passed the 8 rigorous tests set by METAS (The Swiss Federal Institute of Metrology)**
