Buy multiple and swap in seconds for a new look daily! SELECT PROPER WIDTH: Available in 18mm, 20mm, 22mm and 24mm widths to fit thousands of watch models. To determine proper width for your watch, use a metric ruler to measure the lug width of your watch or the width of the current band at the point where it attaches. If your watch has an odd lug width (19mm, 21mm or 23mm), we recommend going with the strap 1mm larger than measured. The material is soft and should squeeze in nicely. OPTIMAL LENGTH: All widths (18mm, 20mm, 22mm & 24mm) measure approximately 10.5 inches (270mm) in length not including the buckle and fit wrists from 5 to 8 in circumference. However, watch size and geometry also impacts fit. If band is initially longer than desired, fold free end neatly back into the keeper loop or cut to desired length. If trimmed, expose cut end to match or lighter flame to avoid fraying. SEATBELT NYLON and SURGICAL GRADE STAINLESS STEEL: Seatbelt style nylon weave 1.4mm in thickness. Perfect to fit the vast majority of watches while remaining lightweight, breathable and very sturdy. Buckle fabricated from 316L surgical grade stainless steel. All materials are hypoallergenic. LASER CUT, PREMIUM STITCHING, WATER PROOF and WASHABLE: Laser cut to eliminate fraying; Custom stitched with clean lines to provide styel and strength. Stink resistant and machine washable.
