Pre-owned Omega Seamaster Railmaster ref 235.10.38.20.06.001 (2025) is the latest evolution of the series, which was relaunched in 2025 with a fresh new look. Earlier Railmasters from 2017 had vertically brushed dials, but this new generation now features gradient dials. The 2025 debut included two 38mm models: a beige-brown model with small seconds and the all-grey version you see here, with three centrally mounted hands. The symmetrical stainless steel case is brushed and polished for balance, paired with an integrated bracelet that features polished and brushed links plus an easy comfort setting for daily wear. The grey dial fades to black at the edge, giving depth to the large white Super-LumiNova hour markers and hands, an homage of sorts to the Railmaster’s origins as a highly legible tool for engineers and scientists. Lastly, this newer Omega novelty is powered by the Co-Axial Master Chronometer Calibre 8806. Shop OMEGA Seamaster Collection
