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.

This 43.50 mm model is crafted in brushed stainless steel and features 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 3 o’clock, 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 8900, 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.

Features
Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Date: The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.
Helium escape valve: Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)
Master Chronometer Certified: Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).
Screw-in crown: Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
Time zone function: Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
Transparent caseback: A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
Unidirectional rotating bezel: A bezel which turns in only one direction. Particularly useful for divers who cannot accidentally rotate it in the wrong direction, which could cause them to miscalculate their dive times. A rotating bezel makes it easy to measure elapsed time.
