1957 was a great year in the history of the Omega watchmaking. In that year, Omega released three new series: Seamaster 300 CK2913, Railmaster CK2914 and Speedmaster CK2915 Replica Watches, which later turns to be a three great series (Seamaster although already come out, but in my opinion that Seamaster 300 meter diving watch is the real one).
These three watches are in similar appearance. Omega Speedmaster Series Cheap Copy Watches are black-faced outline, with broad arrow hour hand, sword-shaped minute hand, and linear sweep second hand. Speedmaster CK2915 bezel is engraved with a tachometer, which is then a revolutionary chronograph design.
