Notes
1910-
hunter calibre
Breguet hairspring
An intermediate wheel between minute pinion and the rest of the train allows a low profile without reducing the sturdiness.
The arrangement of the now four train bearings according to the four brightest stars of the constellation Pleiades gave the calibre its name.
option: Chronometer certificate Neuchatel Observarory
