Unfortunately, I can only give advice based on theory rather than personal experience ...

... since I have not yet tested a cal. 100-equipped watch yet. Therefore, all I can say is based on the movements I have seen and handled both at the dealers and at presentations, and of course based on the conversations with watchmakers and the people developing and producing the movements. Consequently, my advice cannot be authoritative, I apologize.

The cal. 39 is solid and tried, this is correct. however, from the technical point of view, and despite its beautiful aesthetic finish, it cannot deny its rather unsophisticated nature, based on the company's most succesful movement designs from the late Seventies and early Eighties. IN this respect, the new cal. 100 is playing in a different league. Optically, it adhers to the classic tradition of the 2/3-plate design, but is splitting the top plate, to make access easier, which reduces cost and the danger of damages during reassembly.the two spring barrels not only offer a longer power reserve, but also a higher accuracy due to a more stable rate over a prolonged time. The unique and practical second resetting mechanism also assures higher stability of the movement's performance, since the balance wheel is not stopped and has to restart after the reset. Finally, the cal. 100's balance wheel looks more attractive, with its poising screws, but this is an absolutely subjective argument.

Sorry for not being able to offer a better advice.
