Calf leather
The leather most straps are made of: calfskin, smooth or with a grain.
It is comfortable from day one, and smooth leather ages with a patina. Keep it dry. It suits almost any watch, from dress to field.

How it works
How to try on a watch strap online
A strap changes a watch more than anything else you can buy for it. Strap Finder is a virtual try-on for watch straps: see the change before you order, on the watch you own.

Photograph your watch
Lay it flat and take the photo straight from above, with the whole case and the lugs in the picture. The try-on keeps your watch and swaps the strap. No photo at hand? Start on the sketch watch.

Order from the shop
Every strap links to its page in the shop that sells it. Choose your size there and order; the shop ships the strap and handles returns.
Before you order
Know your lug width
The try-on shows how a strap looks, not whether it fits. That depends on one number: the lug width, the inside distance between the lugs of your watch, where the spring bar sits.
Most watches take 18 to 22 mm, odd sizes such as 19 or 21 mm included, and a strap has to match to the millimeter. Look it up for your exact model, read it off your current strap or measure it.
Strap guide
Which strap material suits your watch?
The six strap materials you will come across most often, what each is good at and which watches it suits.
Alligator and crocodile
Reptile leather with large, square scales from the belly or smaller, rounder ones from the flanks. A croco-grain strap is usually calf leather pressed with the pattern.
The most formal look a strap can give. Keep it away from water and perfume. It suits dress watches and formal evenings.
Suede and nubuck
Leathers with a soft, velvety nap. Nubuck is sanded on the outer side and the tougher of the two; suede comes from the softer inner side. Alcantara is a synthetic microfiber with the same look.
A warm, relaxed texture that is soft from day one. Keep it dry. It suits field, pilot's and vintage-style watches; Alcantara suits racing chronographs.
Rubber
Molded FKM, silicone or natural rubber. FKM is dense and durable and gathers less lint than silicone, which is softer and cheaper.
It takes water, sweat and heat: rinse it off and wear it again. It suits dive and sports watches, and the summer.
Nylon
Woven nylon webbing, best known as the NATO strap: one band that passes under the watch.
It is light, tough, quick to dry and washable, and it costs little. It suits field, military and dive watches.
Canvas
Heavy woven fabric with a matte, outdoorsy look. Sailcloth straps look similar; whether they can get wet depends on their backing, leather or rubber.
A rugged, casual look. Cotton canvas soaks up water, so keep it dry. It suits field, pilot's and tool watches.
Questions about Strap Finder
Do you sell the straps?
No. Strap Finder is a try-on, not a shop. Every strap links to its page in the shop that sells it, where you choose your size and order; the shop ships the strap and handles returns. Strap Finder earns a commission on those orders, and your price stays the same. Meet our partner shop.
How do I take a good photo of my watch?
Lay the watch flat on a plain surface and photograph it straight from above, with the whole case and both pairs of lugs in the picture. Soft daylight without hard reflections works best. The strap in your photo does not matter: the try-on keeps the watch and puts the new strap on it.
Does the try-on check that a strap fits my watch?
No. It shows how a strap looks on your watch, not whether it fits. Check your watch's lug width and pick that width in the shop. The Lug width filter in the try-on shows only the straps made in your size. How to find your lug width.
Can I see the strap on my wrist?
Yes. Switch to the Wrist view: the watch with the strap appears on a sample wrist, and with a photo of your own wrist, on your arm.
Which watches work?
Any watch with regular lugs that take a strap, from vintage dress watches to divers. Watches with an integrated bracelet need straps made for that model, which are not listed here.
What happens to my photos?
