Spoke today with OB rep about the availability of the 3861 bracelet to be purchased separately. The rep's response, in short (just recounting here folks, not vouching):

(1) OB rep was as of today able to order the new 3861 bracelets as parts
(2) However, just because they're able to order does not mean they're around the corner from availability
(3) Instead, Omega will be utilizing the bracelet production to first satisfy watch orders
(4) A total armchair-guess of June/July before this OB is allocated a parts-only 3861 bracelet
(5) Price in their system for both bracelets (plexi or hesalite) is $680

I by chance called while they were ordering - so technically I think my name is "first" on a "list" for a bracelet purchase.

 

That’s awesome good timing!!!

 

I ordered mine back in mid Jan (only had the strap hesilite available in the OB at the time so took that).
Arrived yesterday, honestly much sooner than expected....

 

Thanks for the info. I was considering putting the brushed version on my sapphire, but the polished inner links have grown on me as they get less shiny with wear.

 

Maybe they can prioritize those with the strap?

good deal
