Speedy bracelet on a new 42mm SMP300

Vindic8 · Aug 11, 2020

I know many people have put a Speedy bracelet on the 41mm SMPc. However I was looking for any success stories for the new 42mm SMP300.

It seems like the bracelet for the 311.30.42.30.01.006 Speedmaster might be a candidate. Its 20mm lug and a 42mm case.

Looking for any success stories and the model number of the right bracelet.

Thanks in advance.

Historically, Seamaster and Speedmaster bracelets have not been interchangeable.

But, someone might have both and be able to try it for you.

I see them regularly for the 41mm versions. Just want to see if the same can be done for the 42mm.

Ah! What you might not know is that the end links are not the same. The Speedmaster uses 849 last time I owned one and the Seamaster uses 930.

So the question will be, do either the 849 or 930 end links fit the 42mm Seamaster?

I was under the impression the vintage SM300 bracelets were interchangeable with same era speedmasters but I might be wrong?

The truly vintage Seamaster 300 from the 60s? Those are, yes.
