All of our bands have been tested in oceans, pools, showers, etc. Keep in mind though that our bands will not make your watch waterproof!
Our 20mm straps are 8 inches in length (excluding your watch case). There are 10 size settings with .25in increments. The total length of the strap on a Pebble Time Round 20mm (1.5in case) is 9.5in. The smallest wrist size this would fit is 5.6in. The largest wrist size this would fit is 8in.
If at any time you damage your band we’ll replace the entire band (and pins, loops, and buckle) for 50% off of a new band. If at any point you damage your loops, pins, or buckle (with the rest of the band being fine) we’ll replace those components for just the cost of shipping.
