Sourcing a period and fit correct bracelet for a Tudor Sub

[Tudorimposter]

Hi all,

Recently purchased a 7928 and it came on a leather strap.

Looking to get an appropriate bracelet but incredibly confused on how to search for the correct one.

I bought an aftermarket one to test the fit and haven’t been thrilled about how it sat against the case.

I have been trying to eye the end link numbers on other 7928’s I have seen listed but that is about it.

Where do I start?
