Description

The PUW caliber 1561 was a very familiar german selfwinding movement of a good quality. It was launched in 1971 and superseded by the caliber 1661 in 1975.

Typical for the PUW 1561 is its very healthy rotor winding sound, for which the click spring at “9” is responsible. With its help and with the tiny gear at “6:30” the rotor winds in both directions. The decoupling works with another tiny and freely working gear at “6”.

The whole selfwinding mechanism is very sophisticated and complex, but marks the climax of german watchmaking at the early 1970ies.

A tiny detail: The escapement wheel is beared with a very unusual type of cap jewel, since it is not a round one but almost shaped as a block. The advantage of this execution was, that the cap jewel did not have to be removed in a cleaning machine for cleaning the bearing and it was easier to lubricate afterwards.

The rest of the movement is the same, as on the caliber 561, inculding the very complex constructed date correction mechanism. It works by turning the time back and forth, but advances only when the crown is pressed afterwards.
