Quite excited to notice this Seiko 6105-8119 in a $25. junk bag. Running nicely so far. The locking crown does still lock properly. Two issues : Scratched hardlex Crystal- would you suggest attempting to polish thes scratches or try to find an original crown? Are NOS ones available? Does it matter for originality and or value? Second: the bezel will not move. Any ideas on how to get it to release? ie lubricants? Muscle?
