OMEGA Seamaster Railmaster

Omega's Seamaster Railmaster 235.10.38.20.13.001 is a steel watch measuring 38 mm across. The case stands 12.36 mm thick with a lug-to-lug span of 44.92 mm, and the brown dial sits under a domed sapphire crystal with antireflective treatment on both sides. Inside is the self-winding calibre 8804, a Master Chronometer movement certified by METAS and resistant to magnetic fields up to 15,000 gauss. It runs on a free sprung-balance with a silicon balance spring and carries a power reserve of 55 hours. Small seconds appear at 6 o'clock, and the case has a display back showing the movement. The steel bracelet closes with a butterfly clasp fitted with a comfort setting. Rated to 150 metres, the case suits everyday wear without concern for water exposure.
