Happy Friday OF-
Hoping I can tap the knowledge base here to help me get some info on a bracelet that I'm interested in.

The subject watch is a 70's era Constellation, reference #168.042. I saw this example online and am having a difficult time finding the bracelet number; unfortunately the picture of the clasp is not clear enough to make out any numbers. Can anyone ID this bracelet?

Problem #2 is the endlinks. They appear to clearly stamped as '628'. However I can't seem to find an Omega 628 endlink (20mm) anywhere online.

Anyone have any info on these?
