Features: 1. With 3-width options, our straps fit most watches and smartwatches. Measure your watch's lug width in mm, check your watch manufacturer's website for your watch's specs. 2. Our straps will fit wrists from about 5.5" to about 7.7" around, depending on strap width and watch size, which will comfortably fit most men and women. Just pop out your original watch spring bars, then slide the built-in quick release lever on our nylon strap to pop it in. No tools or engineering degrees are required. 3. The wristband is designed with a stainless steel buckle, which is easy to install and adjust and can firmly fix your smartwatch strap in place. Stainless steel makes the buckle closure corrosion resistant. All of this helps the band survives water and sweat. 4. We use two layers of durable 1.2mm thick nylon to make these straps. Strong durable nylon. Heavy-duty stitching. Stainless steel buckle. This washable, waterproof watch strap can handle the office, the gym, and the white water rafting trip and look amazing doing it.
