Measure your wrist and lug width correctly, then pick the right Legacy Strap Collection size. A practical sizing guide for a secure, comfortable fit.
Quick answer
Measure your wrist with a flexible tape just above the wrist bone, then confirm your watch's lug width in millimeters. Legacy Strap Collection leather straps are 20mm at the lug and taper to 18mm at the buckle, so they fit watches with 20mm lugs. Match that measurement to the strap and choose your buckle hardware before ordering.
Start with your watch's lug width, not your wrist
The lug width is the gap in millimeters between the two lugs where the strap attaches. Legacy Strap Collection leather straps are 20mm at the lug end and taper to 18mm at the buckle, so they are designed for watches with a 20mm lug gap. If your watch has 22mm lugs, you need a different strap, such as the TORSK-DIVER Vintage Brown Leather Strap, which is listed at 22mm. Measure the gap with a ruler or caliper; do not rely on the case diameter.
Measure your wrist for length, not just width
Wrap a flexible tape measure snugly around your wrist just above the wrist bone, where the watch sits. Note the measurement in millimeters. Legacy Strap Collection straps are not sold in multiple lengths, so the fit depends on the number of adjustment holes and the strap's overall length. The Black Aged Leather Watch Strap - Large has a longer 130mm/90mm length and 10 adjustable holes, which suits wrists that need extra room. If your wrist measures under about 170mm, a standard-length strap may be a better starting point.
Choose buckle hardware that matches your watch
Legacy Strap Collection straps come with a steel or bronze buckle. Pick the metal that matches your watch case or the look you want. The TORSK-DIVER Vintage Brown Leather Strap offers steel, bronze, or DLC hardware, so you can coordinate with a black or bronze case. Buckle choice does not change the strap length, but it does affect how the watch wears visually.
Step-by-step strap sizing
- Measure your lug width: Use a ruler or caliper to measure the gap between the lugs in millimeters. Common mistake: measuring the case width instead of the lug gap. Write down the number; a 20mm watch needs a 20mm strap.
- Measure your wrist: Wrap a flexible tape around your wrist just above the wrist bone. Common mistake: measuring over a sleeve or too loosely. Compare your wrist measurement to the strap length and number of holes.
- Check the strap length and hole count: Legacy Strap Collection straps are a standard length; the Black Aged Leather Watch Strap - Large is longer at 130mm/90mm with 10 holes. Common mistake: assuming all straps fit all wrists. If your wrist is over about 190mm, choose the longer option.
- Pick your buckle hardware: Select steel or bronze to match your watch case or preferred look. Common mistake: choosing hardware that clashes with the case metal. Hardware does not change fit, but it changes the overall appearance.
- Confirm the taper and attachment: Legacy straps taper from 20mm to 18mm and use quick-release pins on some models. Common mistake: ordering a 22mm strap for a 20mm watch. Match the lug width exactly; the taper is designed to follow the watch case.
Product facts that affect sizing
- Legacy Fume Leather - Midnight Grey: Legacy Fume Leather - Midnight Grey is 20mm/18mm and comes in a steel or bronze buckle. This strap fits watches with a 20mm lug width and tapers to 18mm at the buckle, so confirm your lug gap before ordering.
- Black Aged Leather Watch Strap - Large: Black Aged Leather Watch Strap - Large has a larger length of 130mm/90mm, 10 adjustable holes, and a 20mm width. The longer length and extra holes give more room for larger wrists or a looser fit, but it still requires a 20mm lug width.
- TORSK-DIVER Vintage Brown Leather Strap (Long): TORSK-DIVER Vintage Brown Leather Strap (Long) is 22mm wide with a 130mm/90mm length and hardware options in steel, bronze, or DLC. This is the choice if your watch has 22mm lugs and you need a longer strap with matching hardware.
