Hello

I have this Omega Bracelet with a very uncommon clasp.
It's adjustable like the Doxa SUB Expandro bracelets
Anyone an idea what ref this is?

thanks

No ref number as far as I’m aware, but I think it was made by JB champion. The original endlinks would have been non-numbered too.

The three generations of 5-row BORs:

/edit: @seekingseaquest with the quicker reply AND the better pic.

Early beads of rice bracelets had those sliding clasps. Do note they’re not extensions and I don’t think they’re supposed to be worn while not fully closed.
Of those sliding clasp BoRs, there are two styles. What you have is the first one, the updated ones had the full Omega logo on the clasp rather than having a logo that protrudes it:



They were only produced for a relatively short time, likely because their design is flawed. They break rather quickly.

Indeed they’re less common than the popular version that followed and of which Omega produced millions, but they aren’t rare and not too hard to find.

Not sure if they had an official reference number. If they did it must’ve been 1502. Just like early 7077s (and solid gold ones) didn’t have the reference number on the clasp but we still refer to them as 7077s.

Correct endlinks look like #11s but are also unnumbered.

Hope that helps!

Interesting. If they’re not made to adjust the bracelet length, then what purpose do they serve? As a temporary diver suit-type extension?

To provide more clearance when putting the watch on or taking the watch off the wrist.

Curious what makes you say this? I always assumed they were since they have micro adjustments/ratchets and seem to hold into place fine.

They do at first, but the stress applied on the mechanism in those "open" positions makes the one sliding part jump out of its counterpart rather quickly from my experience. That, plus the visual component - it simply doesn't look like a quality item to me when half-closed. It's a guess/a recommendation, of course.

Got it, good to know. The design is flawed in several ways, I have a couple that had to be welded due to a broken flimsy piece of steel. And agreed on the appearance when extended too..
