Hi everyone. I have what appears to be a 20mm flat link bracelet (if you squint it looks a little like a 1039), but I cannot identify the model it is or what the appropriate end links are.

There's a small 3-81 engraved close to the hinge on the clasp and what appears to be a watchmakers marking on the underside of the clasp.

Let me know what you think and thanks in advance!

Might be an 1175

 

Thanks -- I wonder why it doesn't have the stamp. Now to source a pair of 640 ends....

 

This recent post suggests it is indeed a JB Champion 1175. End links look like #47.

 

Yup. The JB in the triangle from the OP's pic seems to confirm this as well
