Beads of Rice

I need info to allow me to gain a small understanding of the confusing and daunting world of Beads of Rice bracelets. To be specific I have recently purchased a beautiful Seamaster Cosmic gold plated watch, which is just fabulous visually and accuracy. Sadly it is a bit too tight and I need to add a link, and towards fulfilling that end I purchased a used bracelet on Ebay, which l assumed would fit. Well, that didn’t work. So, my band has 523 lug and 166036 with stamping No.12 1068. Now, so far this seems to be a pretty rare critter, and all I am looking for is a link, but with my first effort proving fruitless, I figure I need some guidance on the World of identifying BOR bracelets and what bracelets would offer interchangeability of links. If there exists a chart showing Omega’s bracelets and technical details I’d love to know about it. And, failing that, if someone can tell me what bracelets I could use a link from to add to mine I would be most grateful.

Thank you.

Thank you, the bracelet only was stamped No.12 with no accompanying number. So, you are saying the only number that I need to match is the 1068?

I'm reasonably sure that No 12 identifies the clasp.

Thank you for the info on No.12

I think that this is right. The 12 appears both on the OEM Omega and the JB Champion for Omega (made in the USA) clasps.

Oh well, since I brought up this topic and really appreciate the info folks have shared, thought I'd post a pic of the Seamaster along with a Connie I bought for my wife.
