I know there is a thread already on GF UG end links, but I’m pretty darn confused. I have a brick stretch bracelet with “C” stamped end links. I’d like to use the bracelet with my Polerouter Date ref. 204503-2BD, but the end links don’t fit. Does anyone know which end links I should be searching for? Or is this bracelet just incompatible with this reference to start? The case has just under 18mm lugs and the C end links are 17.7mm. Some pics are included. Thanks for any help y’all can provide!

This should answer your question.

 

I have seen this ref automatic and micro rotor
with H ELs maybe even UX

 

HELs are Heuer and have a different pattern.

I think UX are 19mm whereas the OP's watch has 18mm lug width (despite other 204503 references being 19mm, which is weird in itself).

 

There are U end links in 18mm (U also in 22m but I've seen 18mm) which you could try to see if the curvature was different to the C end links.

I've also come across H end links in 18mm.

I'm afraid I've never had any of these 18mm end links side-by-side to compare the curvature.

 

I meant “H” el (short for end links)

 

Ah, sorry, makes perfect sense now

 

I have the same bracelet, and it was found with 22mm U end links (which seems like a strange fit). These are some old images I took of my end links a few years ago that may be useful:
U = 22mm
UP = 20mm
UW = 19mm

also have a UB that I believe is 22mm (last image)

 

Thanks to all those that responded! Super, super helpful. The search for the right fit continues!
