Hi all, There is a Omega No. 12 BOR bracelet advertised for Constellations on eBay. I'm interested in the piece and would like to seek your kind advice on it. From what I've tried to search on the forum and from Google, I found No. 12 in reference to a number of bracelets including DeVilles. The endlinks on this particular item look to be accurate for a Constellation. I appreciate any advice given!
BOR bracelets themselves are not model specific, one only needs to be concerned with having the correct end-pieces.
Also, I think you need to know precisely which constellation (check the inside of the caseback). Lots of references and thus case shapes, from bumpers to C-shape to quartz!
