Description: Omega Seamaster Railmaster  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.
