Frequently asked questions
How do I measure my watch's lug width?
The most reliable way is to look up your model in the Milano Straps watch archive, also via the "Find your watch's size" box on every product page. If you cannot find it, send a photo on WhatsApp to Milano Straps using the "Verify on WhatsApp" button, or photograph your watch on app.milanostraps.it, which recognises the size. The ruler or calliper between the two lugs remains only the last resort.
Is a ruler enough to measure the lug width?
On its own, no: a ruler placed between the two lugs can give an imprecise measurement if it is not positioned correctly. First try looking up your model in the Milano Straps watch archive, or send a photo on WhatsApp to Milano Straps for a direct check. Alternatively, the app app.milanostraps.it recognises the size by photographing your watch, with a much lower margin of error.
Is the lug width shown on the case back or in the watch's manual?
No, the case back and the manual almost never show the lug width. It's best to look up the model in the Milano Straps watch archive, or send a photo on WhatsApp to Milano Straps for a quick check. Only as a last resort should you measure with a ruler or calliper between the two lugs.
Which leathers can I find among Milano Straps' ready-made straps?
The catalogue by lug width includes nylon, calfskin, alligator, saffiano, suede, cordovan, lizard, stingray and ostrich. Nylon and calfskin pieces are the most numerous, followed by alligator and saffiano; suede, cordovan, lizard, stingray and ostrich complete the selection in smaller quantities. Each strap is ready-made by Milano Straps and should be chosen according to your watch model.
Which lug widths does the Milano Straps guide cover?
The guide and catalogue cover the most common lug widths: 16mm, 18mm, 19mm, 20mm, 21mm, 22mm and 24mm. Each size has a dedicated page where you can see the ready-made straps in that width. To find out which size your watch needs, start from the archive or the WhatsApp verification with Milano Straps.
