Very rare vintage 1958 stainless steel Omega Railmaster 2914-3 SC with original “flat foot” “Mercedes” winding crown, and screw down case back engraved “RAILMASTER,” the Seamaster horse emblem. Inside is the original soft metal non ferrous movement cover for anti magnetic protection. The 38mm diameter solid three-body case, curved lugs, and stepped bezel are polished/brushed. The original black dial has the gilt minute/second scale, radium ochre-colored dart hour indices, a steel broad arrow hour hand and a Dauphine minute hand with luminous inserts. There is a steel center sweep second hand, and luminous Arabic numeral hour markers at the quarter hours. The 12.7mm thick case, dial, and movement are all signed.
This first series Omega Railmaster 2914-3 SC has a mechanical manual winding Omega cal. 284 movement. It’s copper-colored, and constructed with 17 jewels, a shock absorber device, and a straight-line lever escapement. It includes a monometallic balance, a self-compensating flat balance spring, and an index regulator.
The Omega Railmaster 2914-3 SC was launched in 1957. The second in the famous Omega “Master” trilogy of watches (along with the 2915 and 2913), it was designed for professionals who worked near magnetic fields.
