I'm 7.4" and I have had GEN BP Petit Prince on my wrist, defo bulky and heavy watch. Currently I'm wearing 47mm Pam 587 as my daily driver but his sleek design fits me better than bulkiness of the BP. I presume that rep is going to be even thicker than the Gen as usually in rep industry.
No, I believe the rep case will be 1:1.
