MST 366

Description

The MST caliber 366, which was used in Roamer watches is a ladies’ form movement of decent quality. It uses seventeen jewels, a screw balance (not shock protected) and a regulator with a long arm.

The angeled plates, the stripe decoration and the indicated chatons add a very nice appearance, and this is something, which is not too common on those tiny ladies’ form movements.
