The watch comes with extra https://www.crwwatches.cz/Collection/tank/ straps as well. There's a leather https://www.crwwatches.cz/ strap https://www.wuyls.co.uk/ and two rubber straps. Why two you ask? Well, one is longer so that it can be fitted to your body or leg. Shades of 1940s pilot's watches aside, I can see this being super useful for a drummer. The body-strap aspect, I'm not quite sure about.
