Are all 20mm Rolex endlinks interchangeable?

[Royal68]

I’m wondering if all Rolex 20mm endlinks are interchangeable. (Datejust bracelet interchangeable with Submariner, DayDate, etc)

It is not. Some are with the right spring bars (DJ jubilee on Sub) but not all.

Noobie question but is that because the case shape is slightly different?

Because the endlinks are different as well as the cases where the pin holes are drilled. 36mm vs 40mm case diameters play a slight role too.

Those dimensions also vary a bit in 5-digit vs 6-digit models despite sharing a 20mm lug width.

A few are. There is no definitive compatibility list afaik..

They can frequently be used with compromises.

The DJ is a 36mm contour case, the Subs and GMT's are 40mm, so there is a mis-match on the case to end radius.

Some of the drilled holes are slightly different, and spring-bars can be different radius pivots. This means that sometimes using the wrong spring-bar to get the bracelet to fit, you are sticking the wrong size pivot into the lug, and it may wear it oblong.

Research what you want to match and you can often find some alternatives, if not exact matches.

Oh yes there are definitely differences in 5 and 6 digit models. I was thinking of interchanging between datejust 36/41 and the daydate 36/40

Good info. Is there anything you don’t know about watches!
