Stowa Necklace Watch
This lovely watch was inherited by the owner from a grandparent and stopped working after it was dropped - unusual for a watch with incabloc shock settings but not impossible. Upon further inspection, it was found that a previous ‘repairer’ (or watchbreaker) had solved a problem of broken dial feet by simply gluing on the dial. The glue got into the incabloc and the watch stopped being shock resistant, leading to a broken balance pivot. New dial feet need to be properly fitted, as well as the watch being serviced and the balance staff replaced.
