The Hirsch brand is known for quality, and their buckles and clasps are no exception. The Single Fold Clasp is designed with a pressure locking system that snaps into place. No buttons, no fuss.
Extend the life of your watch band with a deployant clasp
Wearing a clasp keeps your adjustment setting in place instead of bending the strap back to fit into a buckle. This constant bending on one point of the strap eventually weakens it.

SIZE (LUG WIDTH)
Your existing band may have the size already imprinted on the back. If not, you can measure the inside dimensions of your watch lugs with a ruler.
We don't recommend measuring your existing strap, your lug space is more accurate.
* If you would like to use your original buckle or clasp, use the same method to measure the inside width of your buckle. Our sizes include the lug and buckle widths for reference (20x16mm = 20mm lug width and 16mm buckle width).
LENGTH
If you have an existing strap that fits well, measure each piece from end to end, not including the buckle for the total length. Otherwise, measure your wrist size with measuring tape or string.
As a general rule, your watch band length should be approx. 1/2" to 1" longer than your wrist size.
Short: 6-1/4" (100 x 60mm) - for wrist sizes under 6" - women's short (very short)
Medium: 7" (110 x 70mm) - for wrist sizes up to 6-1/2" - women's regular, men's short
Mid Length: 7-1/2" (115 x 75mm) - for wrist sizes up to 7" - men's medium
Long: 8" (120 x 80mm) - for wrist sizes up to 7-1/2" - men's regular, women's long
XL: 8-1/2" (120 x 100mm) - for wrist sizes up to 8" - men's long
