This is the caliber 179, a 15 jewel movement and is 9-3/4 ligne or 22mm in diameter. Although these are commonly marked on the pillar plate with the caliber number, usually in the space between the escape wheel finger and the train bridge, occasionally they are unmarked. The key-less works (aka the setting bits) are diagnostic for this movement. It also appears in Alpina marked watches (the cal 575), and Marc Favre marked watches. The setting works on these are very similar to the cal 157 which is patented by M. Favre in 1925.

All I know is based on hard work & writing by others. I can only aspire to augment this body of knowledge. If I am wrong it is because of my own failings. -me

Caliber 179 and Alpina 762 are definitely 100% identical movements. I purchased a nice Alpina watch from the second half of the 20s in 900 silver. The movement does have both markings, the 179 Gruen marking at the plate and the Alpina 762 at the train bridge. I guess that this watch was produced slightly before the Alpina Gruen Guild marketing contract but shows the collaboration that existed before very well.
