Comments about the data

Alpina Gruen Gilde 1929-1937
ingenious: one simple part replaces setting-lever spring, yoke, and yoke spring
differences not known between 575, 762
Gruen lists two balance staffs and two lever arbors for the equivalent Gruen 179. Maybe this lead to two Alpina calibres within the Alpina-Gruen Guild.
It is also considerable that the earlier Alpina 762 was finished by Gruen, and the later Alpina 575 purchased directly from Universal.
Movement registers and staff lists contain only the base calibre Universal 259, and this makes further investigations difficult.

Example, year: signature; shock device
1945: 1218344, Alpina 575, Swiss
(Alpina 575)
