Omega Seamaster Railmaster 235.12.38.20.06.001 38 mm Steel Grey Dial Black Leather Strap Watch

Paired with a black non-grained calf leather strap and steel foldover clasp, this Seamaster Railmaster keeps its 38 mm symmetrical steel case light at 79 g. The grey dial darkens towards black, and its large numerals and hour markers, filled with white Super-LumiNova, remain easy to read beneath a domed sapphire crystal treated against reflection on both sides.

The self-winding Calibre 8806 continues the model's anti-magnetic purpose: as a METAS-certified Co-Axial Master Chronometer it resists fields of 15,000 gauss, with a free-sprung silicon balance spring and 55 hours of power reserve. A transparent caseback reveals its rhodium-plated rotor and bridges with Geneva waves in arabesque, and the case is water resistant to 150 metres.
