Omega’s 1957 anti-magnetic Railmaster in its 2025 form: 38mm steel, grey-to-black gradient dial, and a 15,000 gauss Master Chronometer movement.

Introduced in 2025, this reference is the central seconds version of the current Seamaster Railmaster, a line that began in 1957 as the anti-magnetic member of Omega’s Professional trilogy alongside the Speedmaster and Seamaster 300. The symmetrical 38mm stainless steel case measures 12.4mm thick with 19mm lugs, combines brushed and polished surfaces, and pairs a domed sapphire crystal, anti-reflective on both sides, with a sapphire caseback and 150 metres of water resistance. The grey dial deepens to black at the edge and carries large numerals and hour markers in white Super-LumiNova. Inside is the self-winding Omega Co-Axial Master Chronometer Calibre 8806, resistant to magnetic fields of 15,000 gauss, with a 55-hour power reserve. It is fitted to the integrated brushed and polished steel bracelet with a foldover butterfly clasp and comfort setting, and comes with box and papers, warranty card dated 2026.

For the buyer who wants a time-only steel Omega at 38mm with the anti-magnetic specification the Railmaster was built around. It moves easily between a work week and a weekend without changing straps.
