Strap for Jazzmaster Open Secret

The lug width of the Hamilton Jazzmaster H32746591 is 22 millimetres. This measurement refers to the distance between the internal attachment points on the case and indicates the width your strap must have to fit correctly. You can verify this measurement using a calliper positioned perpendicular to the lugs or by consulting our detailed technical specifications.

The best strap depends on your intended use and aesthetic preferences. For formal applications, we recommend vegetable-tanned leather in havana brown or black, which enhances the model's classical heritage. For sporting or casual contexts, a NATO or vulcanised rubber strap offers superior versatility. Alligator represents a premium option for those seeking an explicit statement of luxury.

Strap replacement requires a specialised tool called a spring bar tool or a very thin flathead screwdriver. Locate the pins holding the strap to the case lugs, insert the tool into the lateral hole of the pin, and gently push outwards to extract it. Repeat on the other side, then align the new strap with the lugs and push the pins back in securely. If you are unfamiliar with this procedure, we recommend consulting a professional watchmaker.

Yes, any strap with a 22mm lug width is compatible with the H32746591. High-quality artisanal straps in Tuscan leather, alligator, NATO, and rubber are available online and ready for dispatch. Ensure your strap has been manufactured specifically for the 22mm lug width to guarantee perfect integration with the case's attachment points.

An artisanal strap made from vegetable-tanned leather typically lasts 3 to 5 years with daily wear, provided adequate maintenance is observed. Durability depends on intensity of use, exposure to water, and prompt drying after moisture contact. Tuscan leather straps develop a natural patina that contributes to the emotional value of your H32746591 over time. Replacement is straightforward and affordable, allowing you to refresh the appearance of your timepiece with ease.
