RAVISA CUSTOM JUMP HOUR 1970's
Here is a nice looking Ravisa... more than likely a custom-made promo or anniversary watch. Really good quality with a thick die-casted brass dial and applied plexi crystal. The movement is the common cheap jump hour calibre BFG582 however this one contains 17 jewels which is a nice bonus. The minute-disc is metal and contains a spring-loaded finger that moves the plastic hour-disc. These plastic discs tend to wear out resulting in rotating minutes without advancing hours. Repairs can be made with some epoxy to rebuild the broken plastic teeth but it will rarely be a reliable fix.
