1171 bracelet on 3861 Speedmaster

Hello OF,

I have an 1171 service bracelet that I would like to put into rotation on my 3861 hesalite in addition to the original fully brushed and Forstner flat link.
My research tells me 633 end links are correct for the “older” models, but does anyone know if these can work for the 3861 shorter lugs as well (with minor tweaking)?
Or are there alternatives?

I did a cursory search of this topic on here and other fora, but couldn’t find a definitive answer.

Subscribed as I also want to know!

I just purchased an 1171 bracelet along with Uncle Seiko 1171 endlinks. I’ll post pics in the next few days if everything fits.

Good to know! I tried the US end links today because they arrived first and they seems to fit nicely. However, the real test will be once the bracelet is attached to them and I try it all on.
