The Kelton 1955 40 ATM is the diver of the brand’s 1955 Heritage line. Its screw-down caseback gives 40 ATM of water resistance, roughly 400 m, far above the 20 and 30 ATM of the other 1955 models. Maison&Objet lists it at an advised price of €599. Other 1955 references use a Miyota automatic movement; I could not confirm the calibre fitted to this diver.

Retailer listings describe a limited run of 100 numbered pieces made in homage to the brand’s birth in 1955, with 10% of profits going to the Fondation de la mer. I found no independent review, so there is no documented community verdict yet. Production status is not confirmed: check Kelton’s official site.
