Built around a 42mm round stainless steel case, this Seamaster Diver 300m features a scratch-resistant sapphire crystal, a uni-directional rotating bezel, and a screw-in crown — all working together to maintain water resistance to 300 metres / 990 feet. A transparent case back offers a view of the Co-Axial Master Chronometer automatic movement within.
The black dial sits beneath that sapphire crystal while the stainless steel bracelet, finished in a combination of brushed and polished surfaces, secures via a push-button folding clasp with push-button quick micro adjustment — allowing a precise, tool-free fit on the wrist.
Carrying COSC chronometer certification, reference 210.30.42.20.01.001 represents Omega's commitment to regulated accuracy in a dive watch that transitions effortlessly from the water to everyday wear.
