This high-quality replacement hinge pin — also referred to as a clasp rivet bar or occasionally a friction bar — is made to fit Omega Seamaster full size watch clasps with the number 1503/825. It will also fit the clasp's wetsuit extension. This part allows you to restore your watch clasp without the need to replace the entire unit.
I have given you clear images of this hinge pin from every angle to help you assess the condition before ordering. The pin in the photos is the exact one you will receive.
If you are not sure if this will fit your watch or if you have any other questions, feel free to email me at Sales@TheWatchLink.co.uk. I'm happy to help!
