Frequently asked questions

What strap is recommended for the H13321813?

For the Boulton, materials that respect the geometric elegance of the case are recommended. Alligator with fine grain (cognac or black) is the formal choice par excellence. Calf leather with vegetable tanning develops natural patina over time. NATO straps in fine canvas offer lightweight daily wear. FKM rubber is ideal for discreet sports contexts.

How do I change the strap on the Hamilton Boulton H13321813?

Use a spring bar tool to remove the elastic pins (spring bars) from the case lugs. Insert the tool into the spring bar slot, apply gentle lateral pressure, and extract the pin. Repeat from the opposite side. Insert the new strap by aligning the holes with the spring bars, then use the tool to reinsert the pins until they click into place.

How long does a leather strap last?

A leather strap with quality vegetable tanning typically lasts 3-5 years with moderate daily use. Durability depends on exposure to UV rays, humidity, and frequency of use. A leather strap develops desirable patina, whilst alligator maintains a more stable texture over time.
