Ref. 220.10.40.20.03.001

The original OMEGA Railmaster of 1957 was a practical yet elegant anti-magnetic watch designed for railway staff or anyone who worked close to electrical fields. Today, that industrial spirit and innovation has been updated for a modern collection.

In this denim-inspired model, the 40 mm symmetrical case is made from stainless steel with a wave-edged design featured on the back. The vertically brushed “blue jeans” dial includes brushed stainless steel hands and recessed hour-markers which are all filled with light grey Super-LumiNova. There is also a beige central seconds hand and transferred “Railmaster” indication which delivers a classic touch.

The watch has a stainless steel bracelet as well as an oriented caseback featuring a NAIAD LOCK design to keep the wording in position. The watch is driven by the OMEGA Co-Axial Master Chronometer Calibre 8806, making it resistant to magnetic fields of 15,000 gauss.
