I thought I'd post some chronograph calibers and identify the brand of watch. For beginners. See if you can identify the caliber and manufacturer and also add anything interesting about that particular movement. When replying, name the watch and caliber. The only rewards a LIKES. Cheers Jim

This is harder than the other one. I recognize this one from the bean shaped coupling yoke and the reset hammer shape (and the logo under the balance) but I don't have anything interesting to say about it.
I'm still a beginner! The stop and reset functions are operated via the same pusher. Only the start is operated by the other.
Obviously, most of these were made by the Seventeen Jewel watch company! One was made for Omega under contract by the "custom shop" arm of the company called 18 Jewel. This helped to hide the identity of the real manufacturer...17 Jewel. I have (well...my wife has) my grandfather's Longines 23Z. Also made by the 17 Jewel company.
Ha! Thought about typing 773x but decided to go for it instead. Will have to study to determine what the "tell" is between the two! Thanks for the game Jim!
