THE PERFECT FIT (for wrist size 5.5" - 8") - Our Adventure Watch Straps are made from beautifully soft and robust silicone and feature an eye-catching Tang Buckle. The combination of twice-brushed stainless steel buckle and comfortable silicone strap ensures this watch strap not only fits perfectly but looks great. SELECT CORRECT WIDTH : Our watch straps are available in 18MM 20mm & 22MM widths only. It is important that your watch’s lug width is the same width of the band you select or our quick-release spring bars will not fit correctly. Measure the distance between your watches lugs in millimetres and if it matches then our straps will fit perfectly. You can also search online for the specifications of your watch. Classic ZG-QTT9-UB7H-BLK3 EASY FIT (Quick-Release) - Simply pop-out your original watch spring bars then slide the built-in quick release lever on your new Adventure watch strap by Spaghetti Cactus into place. You don't need fancy tools or extremely strong fingernails. You can do it quicker than a sneeze. Quicker than a click of the fingers. MONEY-BACK GUARANTEE - Purchasing a strap can be a leap of faith. If you have any issue with our watch straps (issue with fit dissatisfied with appearance unhappy with a dented box) you can return the watch strap and receive a money-back guarantee. No questions asked - because we care. We really do. :)
