As the title states, I am trying to find the reference number for this bracelet in the four pictures below.

I had the following in my notes.
Sharkproof bracelets for Seamasters are as follows:
22mm bracelet: 98000358
21mm bracelet: 98000459
20mm bracelet: 98000360
All three will take a 20mm clasp, reference number 94522023.

When I sent these reference numbers to the Omega Boutique the sent me back a picture of a different bracelet. Please notice the end links of this bracelet are solid rather than individual links of mesh.


Photo credit from the internet, I wish I could give credit but I took these notes a while back.

 

I’m pretty sure that isn’t an Omega mesh bracelet, but an aftermarket one grafted to an Omega clasp. The real Omega bracelets don’t have a solid end-piece, just open mesh. That’s why the pictures from the OB don’t look the same — they show the real deal, this is a put-together job.

 

Shame, I prefer the solid end link.

 

This is 100% false.

The vintage and older style Omega Shark Mesh bracelets with the "seat belt" clasp do indeed have open ends as opposed to "tubes." They are commonly known as reference 1247/237 and 1380/237 in 22/20 and 20/20 sizing, but they also come in 24/20 sizing. These bracelets are sized at the clasp holes but also can be extended via extension mesh pieces.

However in 2010 Omega introduced the newer style mesh which is constructed completely different to work with the ratcheting clasp. This is sized via removable mesh piece links that are held in via pin, and have tubes at the end pieces.

Even a cursory search would bring up this long thread showing the different types and model numbers of Omega mesh....

To the OP:

I don't know if those model numbers are still relevant as around that time they redid their strap/bracelet nomenclature. The last of the "tubes" style mesh pieces I had in had model 021ST1964 for 22mm/20mm and 021ST1962 for 20/20.

 

Thank you @yinzerniner

 

I just picked up a Baby Ploprof with 1247/237 mesh bracelet. The bracelet is adjusted for shortest length but still too long. How can you make shorter? And, did Omega originally sell these to customers in various lengths; like 7 inches, 7.25 inches etc. my wrist is just under 7 but I’d like to get mesh that gives me “room to move/adjust” can you suggest solution? Thanks very much for your advice

 

Pretty sure that model has adjustment holes, so you can use a middle adjustment and then get the mesh cut to length at a manufacturing jeweller. Cut the narrow end.
