Strap for Khaki Navy GMT

The H77595915 requires a lug width of 21.00mm. This measurement is taken between the internal lug holes of the case, perpendicular to the case profile. The 21mm width is a non-standard dimension requiring specialised aftermarket strap craftsmanship.

This depends on intended use. For the watch's tactical character, we recommend a NATO strap in organic woven cotton or an alligator strap vegetable-tanned in cognac or dark brown. Alternatively, an FKM rubber strap delivers maximum practicality in humid environments. All available in 21mm lug width from milanostraps.it.

Strap changes require two tools: a spring bar tool (lever for removal) and a stable flat surface. Position the watch caseback down, insert the lever under one spring bar, lift gently and slide the old strap free. Thread the new strap, ensuring both spring bars seat completely on the case lugs. Repeat on the opposite side.

Yes, fully compatible. The H77595915 uses 21.00mm lugs. Any strap in leather, canvas or rubber manufactured for this width will fit perfectly. Ensure your supplier explicitly specifies 21mm and not adjacent dimensions.

A quality vegetable-tanned leather strap, properly maintained, lasts 3–5 years of daily wear. Longevity depends on ambient humidity, wear frequency and basic care: drying after water contact, avoiding excessive creasing and conditioning with natural balms every 6–12 months. NATO or rubber straps typically last 8–10 years.
