I looked through the guides and did some searching here and on youtube (everything I found there was non-vintage) my apologies if this is a "duh" question. I recently acquired a Calculator 110.663 on bracelet. Even when I adjust the links as far as possible into the clasp I will need to remove a couple of links from the bracelet to fit my wrist. I'm used to either bracelets with screws or with arrows indicating the direction to punch out a pin. Is this an internal middle pin bracelet that needs to be sized with a different technique? I don't want to start banging on pins and break something. Ideally, I'd like to learn how to do this properly and get the tools needed vs. taking it to a watch maker.
