Black Friday Sale 2023 OMEGA Seamaster Professional 300m Full Set Authenticity Certificate

Online price: £3290

Offered here is the stunning "Seaweed" Green rendition of the legendary OMEGA Seamaster Diver 300M. Purchased in 2023, this example is a complete full set, representing the perfect intersection of rugged capability and sophisticated Swiss luxury.


Distinct from the crowd, this model features a mesmerising polished green ceramic dial and matching bezel. The dial showcases the iconic laser-engraved wave pattern, a hallmark of the Seamaster lineage that adds incredible depth and texture. The skeletonised hands and raised indices are filled with Super Lumi-Nova, glowing with a dual-color emission (Blue/Green) for instant legibility in the darkest depths.
Beneath the sapphire crystal caseback beats the OMEGA Co-Axial Master Chronometer Calibre 8800. This is not just a movement; it is a benchmark. Certified by METAS, it is resistant to magnetic fields up to 15,000 gauss, ensuring your timekeeping remains unaffected by modern electronics. With a 55-hour power reserve and a quick-set date function, it is perfectly tuned for daily wear. The 42mm stainless steel case offers professional-grade water resistance up to 300 meters (1000 ft) and features the signature conical Helium Escape Valve.
This watch comes on the robust stainless steel five-link bracelet, featuring OMEGA’s patented rack-and-pusher micro-adjustment clasp. This allows you to instantly fine-tune the fit of the bracelet to your wrist without tools - essential for comfort on hot days or over a wetsuit.
