Seamaster Professional Bracelet locking PIN

My apologies if I'm not in the right section of the forum. Brand new member. If this isn't the right place for this question let me know, I'll delete the post and repost in another section
I broke the mushroom shaped pin that locks the bracelet in place. In the picture, It would be the pin that is in the hole in my bracelet. This is a 1504 826 bracelet. Can the pin alone be replaced or do I need a complete clasp assembly? Thanks for the help

That specific part isn't replaceable with a new part. A talented watchmaker or machinist might be able to "repair" it, however.

You require a complete clasp P/N 117ST1504826 assuming it's a standard SMP reference and not one of the limited or special editions with a unique clasp.

You could install a newer, adjustable clasp:

Your nearest OB will get you the best price for any of these parts.
