Tavannes Cyma co must has listen a lot to their engineers when making watches as they often come up with neat solutions! The Triplex on the dial lets you know of the special case ring design. The case ring has three screws that expand a side mounted spring that secures the case ring to the case with even pressure all around. The movement is a object of beauty! Cyma’s in-house calibre 414 features Cyma’s own shock protection (Cymaflex) and has a very high standard of finishing. And who does not love a waffle dial with rose gold fittings.
Case ref: 1.5637 863. Chrome Case has been restored and in very good condition. Case size 34mm w/o crown. Cyma’s in-house calibre 414 is in Exellent condition and has had a full service by me in May 2022.
