Engineered for the extremes, this Seamaster is built around a 55 x 48 mm titanium case equipped with a helium escape valve and transparent back.

The grade 5 titanium dial is accented with orange aluminum and varnished white hands, delivering striking contrast and uncompromised legibility at any depth. At its core, the Omega Master Chronometer Calibre 8912 ensures precision, anti-magnetic resistance, and a 60-hour power reserve.
