The Railmaster brought back in 2017, sixty years after the original, on the Master Chronometer calibre 8806. The green seconds hand and the aged luminous tone are deliberate period references. Antimagnetism is now handled inside the movement through non-ferrous components, rather than by caging the calibre in soft iron the way the CK2914 did.
- Master Chronometer antimagnetism comes from the movement's own materials, so no soft-iron inner case is fitted.

How do I check a Omega 220.12.40.20.01.001 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.
