Omega Railmaster 2503.52.00 — History & Features

Origins & Heritage

• The Railmaster name goes back to 1957, when Omega launched it alongside the Speedmaster and Seamaster 300. It was designed for people working near strong magnetic fields — scientists, railway workers, technicians.

• The modern 2503.52.00 is part of a revival of the Railmaster identity, combining vintage cues with more recent technology and finishes.

Launch & Timeline

• Introduced circa 2003 / BaselWorld 2003 as part of Omega’s efforts to refresh the Seamaster / Aqua Terra / Railmaster lines with Co-Axial movements.

• Produced through the mid-2000s (2003-2010).

• While retaining classic Railmaster styling, this version brought in modern enhancements (e.g. improved movement, sapphire case-back).
