A very old handwinding movement with cylinder escapement is the Arogno 2, which was made probably in the 1920ies.
On the movement side, you see the typical attributes of an old cylinder movement: Slanted bridges, a safety clutch in an antique shape, a non shock protected balance with long regulator arm on the cock and of course the gilt color of the plates.
On the dial side, this unmarked movement offers a small surprise: Here, a yoke winding system is used already - without pin for function chance (winding vs. time setting).
