Since its debut in 1993, the Omega Seamaster Professional Diver 300M has become a legend among dive watches — celebrated for its balance of technical innovation and maritime elegance. This contemporary 43.5 mm model continues that legacy in bold fashion, crafted from black ceramic (ZrO₂) and Grade 5 titanium, materials chosen for their strength, lightness, and unmistakable visual depth.

The brushed black ceramic dial, laser-engraved with raised wave patterns, offers a striking interplay of texture and light, while PVD titanium skeleton hands and raised indexes filled with white Super-LumiNova ensure legibility in all conditions. A black ceramic bezel with a white enamel diving scale frames the composition, and the signature conical helium escape valve reinforces its professional-grade functionality.

Driven by the Omega Master Chronometer Calibre 8806, certified by METAS for precision and magnetic resistance, the watch offers a 55-hour power reserve and is visible through the sapphire crystal wave-edged caseback. Completing the look is an integrated black rubber strap with a polished-brushed black ceramic buckle, creating a cohesive design that unites cutting-edge materials with Omega’s unmistakable aesthetic.
