Omega

• cal. 284 manual winding copper-finished lever movement, 17 jewels, monometallic compensation balance, anti-magnetic dust cap • black matte dial, luminescent triangular and dagger indexes combined with Arabic 12, 3, 6, 9, large luminescent sword hands, sweep center seconds • large water-resistant-type case, chamfered bezel, screw back • case, dial and movement signed

The movement is running, however we recommend service soon. It appears to be very clean, however with some light oxidation to the edges. The anti-magnetic dust cap fits rather loose as the rim is slightly dented near the crown side. The movement is numbered 15375219. The dial is very nice and has taken on a dark gray color over the years. The numerals appear to be all original and nice. The hour and minute hand are either re-lumed or re-placed, as the original hands were probably skeleton dauphine, however these look very nice and go well with the style of the watch. The case shows general wear, but is in nice condition overall. The back and the lugs have light scuffs from wear and the it has probably been lightly polished over the years. Overall this is a very unusual watch in very nice condition and can be easily recommended to an Omega collector.

Released in 1957, the Railmaster, Ref. 2914, was Omega's response to the growing desire in the market for a watch that would resist high magnetic fields in electro-industrial work.

Originally rated to be safe up to 1,000 gauss (a unit that measures the strength of magnetic fields) due to its double-case construction, it was one of the best anti-magnetic watches in the market at the time. It is said that during this period, Rolex's Milgauss model, whose name comes from its ability to function well up to 1,000 gauss, actually only rated to around 800 gauss.

Part of a trilogy of 'Master' watches, along with the Speedmaster and Seamaster models, the Railmaster had a much shorter production run due to its unusual tool status and its extremely simple aesthetic design.

Today, this model is extremely collectible due to its rarity, style and its part in the history of mid-century technology.
