Seamaster Diver

The Omega Seamaster Diver 300M Master Chronometer reference 210.20.44.51.03.001 is a bold and technically advanced dive chronograph that embodies Omega’s maritime heritage and modern watchmaking excellence. Presented new and unworn, this outstanding pre-owned luxury watch is offered as a full set with its original box and papers.

The watch features a substantial 44 mm case crafted from stainless steel, complemented by a luxurious 18k Sedna™ gold bezel, Omega’s proprietary rose-gold alloy known for its enduring colour. The unidirectional rotating bezel is fitted with a blue ceramic insert and Sedna™ gold diving scale, delivering both durability and refined contrast. True to the Seamaster lineage, the watch offers 300 metres of water resistance, making it suitable for professional diving.

The striking blue ceramic dial is laser-engraved with the signature wave pattern, a hallmark of the Diver 300M collection. Skeletonised Sedna™ gold hands and applied hour markers are filled with Super-LumiNova, ensuring excellent legibility in low-light and underwater conditions. Chronograph sub-dials are harmoniously integrated, while the discreet date display adds everyday practicality.

Powering this chronograph is the Omega Co-Axial Master Chronometer Calibre 9900, an in-house automatic movement certified by METAS. Resistant to magnetic fields up to 15,000 gauss, it delivers exceptional precision, reliability, and a robust 60-hour power reserve, representing the highest standards of contemporary Swiss watchmaking.

The watch is fitted with a stainless steel and Sedna™ gold bracelet, offering comfort, durability, and a refined two-tone aesthetic.
