Hey Farzan, Sorry to hear about the fit issues you're experiencing. All of our straps are designed to fit exact lug widths. [20mm, 21mm, 22mm...etc] It sounds like your lug width may actually be an odd size of 23mm, which certainly explains the fit issues you're experiencing. We encourage you to shoot us an email at info@bartonwatchbands.com and we're happy to help make things right!
