New. Fits any 20mm size at the bracelet end.

The "20mm" refers to the width of the clasp where it attaches to the watch strap, not necessarily the watch's lug width.

​It's crucial to understand that the clasp width is not always the same as the watch's lug width. The lug width is the distance between the lugs on the watch case where the strap attaches. While many straps taper, meaning they are wider at the lugs and narrow down towards the clasp, some straps maintain a constant width. Therefore, when purchasing a replacement clasp or strap, you need to measure both:

​Watch Lug Width: The distance between the lugs on your watch case. This determines the width of the strap that will fit your watch.

​Clasp Width (or Buckle Width): The width of the existing clasp or the desired width of the new clasp. This is the measurement of the strap's end where the clasp will attach.

​For example, a watch might have a 22mm lug width, but the strap that fits it could taper down to 20mm at the clasp, requiring a 20mm clasp. If you tried to put a 22mm clasp on that tapered strap, it wouldn't fit. Always measure both points to ensure compatibility.
