Handmade in Italy Selected leathers

A unique piece – in the literal sense. The Grand Cavalier Cuir originated from a British Ministry of Defence project: a one-piece strap that slides under the watch case, eliminating the problem of spring bars. If one fails, the strap remains on the wrist. This is not a minor detail.

The one-piece construction is what sets it apart from any other strap on the market. No vulnerable joints, no predictable breaking points. A continuous strip of leather — crafted in Italy — that embraces the case from side to side with the same logic as military service straps: to always function, in any condition.

On the wrist, the leather is immediately noticeable — soft, flat, with a contained thickness that does not interfere with the glove-friendly cuff of a suit or jacket. The brown is warm, mature, suitable for watches with history. Compatible with Omega Speedmaster and Seamaster, among others.

One of my favorites so far. All leather make this a master crafter item. The sizing is either a bit loose on my wrists, or too tight. Wish there was a refined way to size for an irregular wrist.

One of the best watch straps I own.

Best value for money strap that I own. This strap holds my Khaki Field Mechanical 42mm and I love it. The buckle sits off the side which was weird at first but when you realize this is done so that it doesn't rub or get scratched - absolutely brilliant. I actually came back to the site today to purchase one of these in black for a new watch and realized I never wrote a review.

Beautifully crafted and buttery soft

Beautifully crafted and buttery soft leather. Love how this strap looks on my watch. Looking forward to ordering more styles.

Great product

Use on Nardin ww1 watch

Don’t buy the Omega one, get this

If you have enough space between the lug holes and case of your watch, this will slip in no problem. Otherwise, you need a high quality pair of curved spring bars to make clearance. After that, you can enjoy this beautiful strap. It even smells better than the OEM Omega strap.

Frequently asked questions

What sizes are available?

20mm and 22mm at the lugs. The total length is 255mm, and the thickness is 2mm.

How does it work without spring bars?

It's a one-piece strap: a single strip of leather that passes under the case from side to side. It doesn't need a spring bar to stay on the wrist, and if one bar fails, the strap still remains attached.

Can I have it with traditional spring bars instead of the one-piece loop?

Yes, this can be done upon request. The price stays the same, and it takes about one extra week. Could you confirm the size, 20mm or 22mm?

Will it fit my Omega Speedmaster?

Yes. It's compatible with the Speedmaster, Seamaster, and in general with watches with 20mm or 22mm lugs.

Does the brown leather darken with use?

The leather develops character over time and softens on the wrist. It's 2mm thick, so it stays flat and doesn't add bulk under a sleeve or glove.
