OMEGA Seamaster Railmaster

The Omega Seamaster Railmaster 235.12.38.20.13.001 has a steel case measuring 38 mm across. Case thickness comes to 12.36 mm, with a lug-to-lug span of 44.92 mm. A domed sapphire crystal with antireflective treatment on both sides sits over the brown dial, and the caseback is transparent. Inside, the self-winding calibre 8804 runs the show, a Master Chronometer certified movement resistant to magnetic fields up to 15,000 gauss, with a small seconds subdial at 6 o'clock and a power reserve of 55 hours. The brown grained calf leather strap closes with a steel foldover clasp. Water resistance reaches 150 metres, more than adequate for daily wear.
