Omega Seamaster Railmaster Small Seconds 235.10.38.20.13.001 38 mm Steel Brown Dial Watch

A small seconds subdial at 6 o'clock sets this Seamaster Railmaster Small Seconds apart from its three-hand counterpart. The 38 mm steel case, brushed and polished, frames a beige dial with a black gradient, large vintage Super-LumiNova numerals and hour markers, and a beige varnished seconds hand. Brushed and polished links form the integrated bracelet, closed by a butterfly clasp with comfort setting.

Calibre 8804 drives the display: a self-winding Co-Axial Master Chronometer certified by METAS, resistant to 15,000 gauss and running with a free-sprung silicon balance spring for a 55-hour power reserve. Its white rhodium-plated finish with Geneva waves in arabesque can be admired through the sapphire crystal caseback. The watch is water resistant to 150 metres.
