The Omega Seamaster Diver 300M is one of the most recognizable and technically advanced dive watches in modern production. This 42mm reference features a refined grey ceramic dial with Omega’s laser-engraved wave pattern, paired with a blue ceramic unidirectional bezel for a clean yet striking contrast.
Skeletonized hands and applied indices filled with Super-LumiNova ensure excellent legibility, while the date window at 6 o’clock maintains symmetry across the dial. The stainless steel case is rated to 300 meters of water resistance and incorporates Omega’s signature screw-down crown and conical helium escape valve at 10 o’clock.
Powering the watch is Omega’s Master Chronometer Caliber 8800, a self-winding Co-Axial movement certified by METAS. Resistant to magnetic fields up to 15,000 gauss, the movement offers exceptional real-world reliability along with a 55-hour power reserve. The movement is visible through the sapphire exhibition case back.
Finished on a blue rubber strap with a stainless steel buckle, this Seamaster Diver 300M balances professional dive capability with everyday wearability, making it a versatile option for daily use, travel, or collection rotation.
