I have an old 17-jewel lady's watch with the Vulcain name on it, and I'm trying to ID it. I picked it up in a junk bag at a Goodwill outlet so I have no provenance on the watch. Some details make me suspect that instead of an old Vulcain, it may be an old forgery.
The watch face itself is marked VULCAIN above the hands, 17 JEWELS below, them, and simply SWISS at the very bottom; the hands show some corrosion under high magnification. The band also shows some corrosion and is marked HONG KONG on the clasp. The watch back is stamped PROSPECT / HONG KONG inside.
The movement itself doesn't identify the maker, as far as I can tell. Looking at it with the stem at right and the largest gear on top, it has the following three markings:
(1) to the right of the gear, stamped vertically, is 17 JEWELS / SEVENTEEN
(2) at the base of the stem there is a marking A4.
(3) At bottom right, underneath some sort of wheel thingy (that term should tell you how much I know about watch movements) is the one identifier I could find. It appears to say 6061-27, and beneath that RAX.
Can anyone point me in the right direction?
