Urofa 522


The Urofa caliber 522 (also known as Alpina caliber 659) was made in the late 1930ies in Glashütte, Germany. It reminds in color and form of an pocketwach movement, but it was used in ladies' watches.

With 15 jewels, anchor escapement and non-shockprotected screw balance was an up-to-date movement of that time.
