However, these patents do not seem to describe the possibility of realizing the 3 chronograph functions: start, stop and reset, but only the reset function.
Part of the Nicolet Watch patent may therefore be dependent on a Büchler patent, but Nicolet Watch does have a new invention.
The Nicolet Watch no-pusher chronograph was manufactured for some fifteen years, and several versions were produced.
- a gold version was presented at the 1958 Basel Fair
- in 1960, this chronograph was available in a gold-plated case with a steel back, or an all-steel, water-resistant case.
The water-resistant versions, which are quite rare, may bear the Transmarine trademark, registered by Nicolet Watch in 1962.
Other brands have also been used for this chronograph.
