These are 20mm wide nylon NATO watch bands. They will fit any watch that requires a 20mm band. Looks great on our Discovery Watch, but can work for others as well.
NATO bands are great for physical activities. If the strap is cut or broken, you still won't loose the watch. They are waterproof, sweat-proof and generally indestructible. Oh, and they are really comfortable as well. You should have a NATO strap for every watch you own.
