The Heritage
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.

How do I change the strap on my Hamilton Khaki Navy H77251135?
Strap replacement requires specific tools: a spring bar removal tool or pin extractor, a small hammer, and a protected work surface. Position the watch in a watchband holder, locate the side pins, and remove them with light, methodical pressure. Insert the new spring bars into the replacement strap, then secure them to the case lugs. If you lack experience, consult a professional: Atelier Casati Milano offers this service during a consultation.
How long does a leather strap last on a watch like the Khaki Navy?
Durability depends on material and usage. Quality alligator, with natural patina, develops positively over time and can last 5-10 years of daily use before replacement is needed. Calf leather, being more robust, reaches 6-8 years. Durability increases if the strap is dried regularly after moisture exposure and protected from prolonged direct sunlight. Treatment with natural waxes extends useful life by 1-2 years.
