Lug width to be confirmed

On this Hamilton Boulton H13321821 the lug width doesn't convince me, and I don't want to give you a number I'm not sure about. Write to me on WhatsApp with the reference or a photo of the watch: I'll check it and tell you myself.

Frequently asked questions

How do I change the strap on my Hamilton Boulton?

Strap replacement requires simple tools: a spring bar removal tool or a blunt knife tip. Position the watch on a soft surface to prevent scratches. Insert the tool into the lug hole from the opposite side of the lug, compress the internal spring slightly, and slide the lug outward. Repeat for the other side. For reassembly, align the new strap and insert the spring bars with a decisive movement until they click. Avoid forcing beyond what is necessary.

How long does a leather strap last on my Hamilton Boulton?

The longevity of a leather strap depends on material, usage, and maintenance. A well-cared alligator or shell cordovan lasts 7-10 years in daily use. A vegetable-tanned calf resists on average 5-7 years. Leather, exposed to perspiration, moisture, and UV rays, develops patina and ages naturally. To extend useful life, we recommend periodic cleaning with a dry cloth, avoiding baths and showers, and rotating multiple straps to reduce concentrated wear. Professional servicing at the Casati Milano atelier can regenerate and significantly extend strap life.
