About the product

The OMEGA Railmaster, first launched in 1957 as part of a professional trilogy with the Speedmaster and Seamaster 300, was designed for engineers and scientists exposed to magnetic fields. Today’s 38 mm stainless steel Master Chronometer models honor that legacy with anti-magnetic tech, gradient dials, transparent casebacks, and minimalist design.
