    I'm interested in what became of Andre Frey after he designed the legendary Venus caliber 175 ...

    produced from 1940-1963 by Fabrique d'Ebauches Vénus S.A. in Moutier, Switzerland. In 1962 the Tianjin Watch Factory (aka Sea-Gull) acquired the caliber 175 tooling from Venus for use in the production of the original 1963 Chinese Air Force chronograph watches. The Seagull ST-1901 chronograph movement is based on the Venus caliber 175. The 175 was a column-wheel manual wind chronograph. The caliber 175 was the basis for the Venus caliber 188. The 188 was a cam acuated design. In the mid-1960s Venus was acquired by Valjoux and the 188 was renamed 7730. The 7730 (Venus caliber 188) was the basis for the legendary 7750. Thus Andre Frey's connection with the 7750.

    Well, the next movement he worked on was the Minerva Pythagore cal. 48 (1943). There's an interview with his son here: Interview with Jean-Jacques Frey - TimeZone

    The 7730 doesn't have much in common with the 7750. The method of running the chrono-seconds is different, the cam action is slightly different, the reset hammer is tripped, not part of the cam....

    The 7730 is much more the basis for the 7733, which is largely an evolutionary dead-end.
