    Reference 2509 is the equivalent of reference 2508, but with subsidiary seconds rather than center seconds.

    It was in production from 1950 to the late 1960s and it features an evolution: early versions are fitted with lozenge-shaped indexes, later examples, such as this one, with lapped indexes and beady minute divisions. The calibre powering the model undergoes changes as well: while at the beginning it was cal. 12 120, it then became 12 400.
    Cal. 12-AM400, an evolution of cal. 12-400 featuring improved antimagnetic capabilities is found only an a restricted minority of watches, made at the very end of the production. The present piece in fact features this rare and very refined movement.

    The case of the model is a waterproof screw back case, furthermore featuring an internal dust protection cap which amplifies its antimagnetic features. All cases of references 2508 and 2509 ere made by Geneva-based casemaker Taubert, identified not only by the number 11 within a key, stamped inside the back, but also by its logo FB, also found inside the case back.
