I need to replace a part on my Omega Seamaster bracelet. Please refer to the photo. This is part of the extension bracelet. Do you see part that has the circular hole? That’s the only portion of the clasp I need to replace. Any idea what that specific part is called? I want to search that piece only. Any help is much appreciated.

 

The part is not available as a separate part. You have to buy the whole clasp...
