The Omega Seamaster Diver 300M, reference 210.30.42.20.01.001, is the fourth-generation Seamaster 300M, reintroduced at Baselworld 2018 with one of the most significant updates in the collection's history: the return of the iconic wave-pattern dial, a new in-house Co-Axial Master Chronometer movement, and a level of technical ambition that set a new benchmark for the sport watch category. This certified pre-owned example from 2025 is offered in excellent condition and comes with its full original set, including box, papers, and all original accessories.
Crafted in stainless steel with a black ceramic bezel insert, the 210.30.42.20.01.001 presents the Diver 300M in a beautifully resolved 42mm round case measuring 13.56mm in height, water resistant to 300 metres with a helium escape valve and screw-down crown. The unidirectional rotating dive bezel with its 0-60 graduated ceramic insert and the sapphire crystal caseback complete a package built to professional diving standards.
The black ceramic dial is one of the most beautiful and distinctive in the dive watch category, featuring Omega's revived wave pattern in relief that gives the surface a three-dimensional depth and texture that rewards close attention, with applied sword-shaped luminescent hands and dot and stick hour markers delivering outstanding legibility in any condition.
Powering the watch is the Omega Calibre 8800, a Co-Axial Master Chronometer movement certified by METAS, offering outstanding precision, exceptional resistance to magnetic fields exceeding 15,000 gauss, and a 55-hour power reserve. Visible through the sapphire crystal caseback, it is a movement that rewards the technically curious and reassures the practically minded in equal measure.
The watch is fitted with a stainless steel bracelet with Omega folding clasp, completing a coherent and robust package built for a lifetime of daily wear.
