Seamaster Diver 300M 42 mm

The Olympic Games Paris 2024 will mark the 31st time since 1932 that OMEGA has fulfilled the vital role of Official Timekeeper at the Olympic Games. To celebrate that historic occasion, this special Seamaster Diver 300M offers a sporty design in white, gold, and black - following the official Olympic colour chart.

The 42 mm case is crafted from stainless steel and 18K Moonshine™ Gold, with a bezel that features a laser-structured diving scale in positive relief, and a single dot of Super-LumiNova at 12 o’clock.

Behind the domed and scratch-resistant sapphire crystal on the front, the laser-engraved white ceramic dial has been given a matte finish with polished waves in positive relief. Along with transferred markings in dark grey, the date display at 6 o’clock is inscribed with Paris 2024 typography in black. All of the hour markers are presented in diamond-polished 18K Moonshine™ Gold with white Super-LumiNova, while the facetted hands are finished with an 18K Moonshine™ Gold PVD treatment, including the central seconds hand with its Paris 2024 logo.

On the reverse side, the commemorative stainless steel caseback includes OMEGA’s patented NAIAD LOCK. There is a stamped medallion with a mirror-polished and frosted Paris 2024 logo in 18K Moonshine™ Gold, along with the stamped words, "Paris 2024" and the Olympic Rings, which are mirror-polished on a frosted structure.

The watch is set on a stainless steel bracelet with OMEGA’s new Quick Change System and a patented rack-and-push extendable foldover clasp with extra diver extension. It is driven by the OMEGA Co-Axial Master Chronometer Calibre 8800 and is delivered in a special presentation box.

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.
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.
