Omega Railmaster Co-Axial Master Chronometer reference 220.10.40.20.01.001 2020)

Heritage Narrative
First launched in 1957, the Omega Railmaster was designed as a tool watch for professionals working near strong magnetic fields. It became part of Omega’s legendary “Trilogy” alongside the Speedmaster and Seamaster, defined by purposeful design and technical resilience.

The modern Railmaster, reference 220.10.40.20.01.001, pays homage to that heritage while integrating 21st-century engineering. Its vertically brushed black dial, vintage-inspired beige Super-LumiNova markers, and “crosshair” detail recall mid-century aesthetics, while the Master Chronometer calibre 8806 offers state-of-the-art resistance to magnetic fields up to 15,000 gauss. With a 40 mm case in brushed steel and a robust steel bracelet, this 2020 example blends understated style with everyday practicality — an ideal choice for collectors who value authenticity and technical mastery.
