OMEGA Seamaster Railmaster

First introduced in 1957, the original OMEGA Railmaster was designed for professionals working near railways and strong magnetic fields. As part of OMEGA’s iconic professional trilogy—alongside the first Speedmaster and the Seamaster 300—the Railmaster stood out for its innovative anti-magnetic design, featuring a protective inner case shielding the movement from magnetic fields up to 1,000 gauss. Today’s Railmaster continues that legacy with a modern collection of 38 mm stainless steel Master Chronometer models, blending vintage inspiration with contemporary precision—ideal for engineers, technicians, and scientists working around electrical equipment.
