A 21 mm watch strap is rarely searched for, so the choice in this size is narrow: our range includes a genuine 21 mm Tissot strap and the Hirsch Duke L. This odd lug width turns up on some Tissot and other brand men's models, where a 20 or 22 mm strap simply does not fit. As an official Tissot dealer, we can give you a precise answer about the genuine straps.
Which watches have 21 mm lugs?
Mainly a few brand men's models whose designers matched the strap to the proportions of the case. If your old strap says 21, do not try a 20 mm one: the gap will show, and over time the strap wears out at the spring bar.
Genuine Tissot strap or Hirsch Duke?
For a Tissot watch the genuine strap is the sure thing, because it was made for the brand's buckle and the shape of the case. Tissot is a Swiss brand active since 1853 and part of the Swatch Group, and with us you find the official range. For another brand's 21 mm watch the Hirsch Duke L is a good choice: an everyday leather strap in a longer version, for larger wrists.

21 mm watch straps – questions
Is there a genuine 21 mm Tissot strap?
Yes, our range includes an original 21 mm Tissot strap. The product page shows which model it was made for.
Can I put a 20 mm strap on a 21 mm watch?
It is not worth it, because the narrower strap moves between the lugs and wears. Choose the exact size; if you are unsure, measure the inner distance between the lugs with calipers.
How do I check that I need a 21 mm strap?
Look at the number on the back of the old strap, or measure the inner distance between the two lugs of the case. If it comes out at 21, do not round it to 20 or 22.
