Made to Measure

The strap for this watch is made to measure

On the Hamilton Khaki Navy the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

How do you change the strap on the Hamilton Khaki Navy H77211815?

Changing the strap is a simple operation. Position the watch with the case facing upward on a clean surface. Using a spring bar tool, gently push inward to release the pin from the lug slot. Remove the pin and take off the old strap. Align the new strap with the holes and reinsert the pin, ensuring it clicks into position. Repeat the procedure on the other lug. If you do not have a spring bar tool, Milano Straps offers strap-changing service at the Casati Milano Atelier by appointment.

How long does a leather strap last on the Hamilton Khaki Navy H77211815?

The lifespan of a leather strap depends on material quality, frequency of use, and maintenance. High-quality leather such as that used by Milano Straps can last 3-5 years with moderate daily use, developing a beautiful patina over time. With regular care (gentle cleaning, drying after moisture exposure, occasional conditioning with specific balms), the lifespan can be extended. Nylon NATO straps, on the other hand, are virtually indestructible and maintain their properties even after 10+ years of intensive use. Milano Straps recommends having at least two straps to rotate seasonally and prolong their longevity.
