Correct me if i am wrong but I think you will find it is 19mm. Cheers

Hi Len,

You're wrong, consider this a correction or re-confirmation.

It is 20mm, I know it to be 20mm as I supplied Peter Cohen a 20mm Ron Sabo Bracelet [measured it myself] for his PVD project.

I happen to have my stainless Steel "non-Pasadena" Pasadena [750.501-3] right here [and this is the watch pictured below in my footer graphic below by the way], just measured it again, and the bracelet on it measures 20mm. Sure, you can fit a 19mm strap to a watch with a 20mm lug width, but there isn't any way for a bracelet which measures 20mm is going to fit on a watch with a lug width of 19mm. Unless someone does some Dremel grinding work, which has not been done to this watch.

I am at a loss how to reconscile your measurement and mine, Len. But I own quite a few of these, both PVD, and plain Stainless... Heuer, Tourneau, even the 510.5xx models and the Montreal's. They are 20mm in my experience and via my caliper

Cheers!
