Omega Railmaster.
The Railmaster was first released in 1957 as part of the famous Omega technical “master” triumvirate, alongside the Seamaster and the Speedmaster models. The Railmaster heralded a double-housing case and special dial design that helped it withstand extreme magnetic fields, making it useful for railroad engineers, scientists, electricians and technicians. The modern interpretation of the Railmaster unfortunately lacks the same technical features as its predecessor, but fortunately it’s still a very handsome watch.
