I have been shopping recently and noticed the 3510.82 (Japan Limited Edition) Speedmsster listed as a 35.5mm case size and others listed at 39mm.

Does anyone know if the 3510.82 was offered in two sizes? 35.5 and 39mm or just 39mm.....?

Any information/ assistance is appreciated- thanks.

 

I think it shares the same movement and case with the regular 3510.50, therefore 39mm?

It is a 39mm case

 

Yeah - thanks I did some digging and came to that same conclusion......3510.50 3510.52 3510.21 and 3510.82 all have the same case and size.....

 

39mm. At some point Omega had it as 35.5 or thereabouts on their website

 

Yeah, because of the Omega measuring system. Ha! Glad they do it like the rest of the universe now

 

It's that Swiss precision, what's 3.5mm between friends.
It's 39mm as the mid-90's schumachers used the same case as well.
