Omega Seamaster Diver 300 M

This Seamaster combines titanium with ceramic — the lightest practical case metal against the hardest practical bezel material — which is why it neither weighs on the wrist nor marks with wear. The 42mm case houses a laser-engraved ceramic dial bearing the wave pattern in relief and a conical helium escape valve operable underwater. Inside runs a Co-Axial Master Chronometer calibre, METAS-certified to resist magnetic fields of 15,000 gauss.
