AS 1101

Description

A rather rare cylinder form movement is the quite tiny AS 1101, which was used in ladies’ watches, probably in the 1940ies. These kind of movements already show signs of modern pallet anchor movements of the same time (shaping of the briges, silver colored plates, dial footer screw on the side of the movement) and were probably made as cheap alternatives to pallet anchor movements.

Of course, the precision of these kind of movements is rather poor and since the cylinder wheel always touches the balance axle, it can happen that the movements once in a while just stops, especially when the last service was long ago. There movement shown here makes no exception.

The balance wheel and all gears except the minute gear, run in synthetic rubies, the bridges show nice decoration and anglage and even on the dial side, it’s a pleasent view to see the large servicing holes and tne simple, but very well made rocking bar winding mechanism.

This movement, which is already stamped with the modern “AS” marker, displays hour and minute.

Interestingly, AS stamped this movement as “AS 1037”, but it is in fact the AS 1101 with its slanted main plate.
