The textile strap that came with my 10 day PP was 22mm from lug to clasp. This croco strap tapers from 22mm to 20mm at the clasp. I think the issue might be how the clasp folds inside the strap. I never get a "perfect" fit with deployment buckle and clasps vs regular tang buckles.Nice! I'm thinking I may (unfortunately) need to put my new ProPilot Altimeter on a different strap. Love the textile look/clasp but can't get a "fit" that feels right. I know it's a large, heavy watch but it's either slightly too tight or slightly too loose with the adjustment. Do you think leather with buckle could support the Altimeter heft, sufficiently?
