The first Speedmaster, from 1957, part of Omega's professional trilogy alongside the Seamaster 300 and the Railmaster. It was designed for motorsport timing, not space — the tachymetre scale on the bezel was the innovation, being the first chronograph to put it there rather than on the dial.
Key dates.
- Launched with broad arrow hands and a steel tachymetre bezel
- Broad arrow hands and the steel bezel are unique to the earliest Speedmaster references.

How do I check a Omega CK2915 with Watch Safe?
Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
