Can anyone please tell me where I can obtain an Incabloc spring for the lower balance jewels for the following type watch: Swiss movement, about 6 3/4 or 7 ligne, marked on the movement "INT" and on the dial "Dynasty" (is that a brand name?), dating from perhaps the 1940s (???). There is about 2/3 of the spring left; one leg, the base, and about 1/3 of the other leg. I tried to put that back in the fitting, but it doesn't seem to want to hold. Any help would be appreciated. Thanks,
Pete Belmonte
