Railmaster Omega Co‑Axial Master Chronometer 40 mm
Steel on steel
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.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
