The strap that holds a watch on your wrist. It can be leather, metal, rubber, cloth, or plastic. 'Watchband' is the normal American word; British speakers usually say 'watchstrap'. Both are understood everywhere, so nobody will be confused either way — it just sounds a little American. The word covers two quite different-looking things: the soft strap with a buckle that goes through holes, and the metal one made of small links that closes with a clasp. English does not separate them; both are watchbands. Note that the band is only the part that goes around your wrist. The round part with the face and hands is the watch itself, or the 'case'. So when a band breaks, the watch is fine — you take it to a shop and they put a new band on it for a small price. People also say 'band' alone when the situation is clear: 'This band is too tight.' A little unexpectedly, English speakers sometimes use 'watchband' for the fitness kind too (a Fitbit band, an Apple Watch band), even though those are not really watches in the old sense.
