OMEGA Seamaster 300

The Omega Seamaster 300, reference 234.30.41.21.03.001, is a dive watch with a 41 mm steel case. It measures 13.85 mm thick with a lug-to-lug span of 48 mm, and the blue dial sits under a domed, scratch-resistant sapphire crystal with antireflective treatment. A unidirectional rotating bezel surrounds the dial, and the screw-down crown works alongside a self-winding calibre 8912. This Master Chronometer movement carries METAS certification, resists magnetic fields to 15,000 gauss, and stores 60 hours of power reserve; it also includes a time zone function. The steel bracelet closes with a foldover clasp fitted with a comfort setting. A transparent caseback shows the movement's Geneva waves in arabesque finish. The screw-down crown helps hold the case to its 300 metre water resistance rating.
