I was musing on the subject of strap sizing yesterday.
In particular on the challenges of fitting to Breguet watches with the single deployant and large lug to lug measurements. Here is my Classique on a Camille Fournet Taurillon calfskin strap - color sapphire.
I sized on a short set Breguet strap for my Tradition and then adjusted to 55/115 - due to the long single deployant. 
I’m really impressed by the quality of Camille Fournet - the only downside being that I have to collect any alligator straps from Paris due to CITES shipping restrictions.
Now that I have the sizing sorted I’ll try Jean Rousseau in London - more convenient for me. I have a number of their straps on my FP Journe CS.
I have to say that I find the regularity of the CF hand stitching better than JR as well as the other elements of the finishing - bonding of the lining around the lug ends.
I’ll be interested to see how their bespoke straps make out, as the FP Journe came with the JR straps - not sure if the quality control will be any different.

This may be of little help
it's the overhang you can see in the upper right that always gets me with Classiques 37mm
