Frequently asked questions

What is the lug width of the Hamilton Boulton H13321812?

The lug width of the Hamilton Boulton H13321812 is 16 millimetres. This non-standard measurement requires careful selection of aftermarket straps, as most manufacturers focus on 18mm, 20mm or 22mm widths. To verify compatibility, measure the distance between the two lugs of the case: it must correspond exactly to 16 millimetres.

Which strap is best suited for the Hamilton Boulton H13321812?

The ideal strap depends on the intended usage. For formal occasions, we recommend black alligator or shell cordovan, which maintain Art Déco aesthetics and develop patina over time. For daily wear, dark brown or black vegetable-tanned leather offers practicality and durability. A dark blue NATO strap suits informal contexts, while grey FKM rubber amplifies the technical character. All 16mm straps must be selected from specialist catalogues.

How do you change the strap on the Hamilton Boulton H13321812?

Strap change requires minimal tools: a spring bar remover or a thin, flat instrument. Remove the rear lug first by gently pressing on one end of the spring bar pin until it disengages, then repeat for the front lug. Position the new strap by aligning the pins with the lug seats and press until complete insertion. Verify that the strap is secure at both contact points before wearing. If inexperienced, entrust the task to Atelier Casati Milano's professionals.

Are there aftermarket straps compatible with the Hamilton Boulton H13321812?

Yes, the aftermarket offers numerous options for the 16mm lug width. On milanostraps.it you will find a comprehensive collection of straps in alligator, shell cordovan, vegetable-tanned leather, NATO and FKM rubber, all specifically selected for this width. Straps are ready for shipment and customisable online, with additional services available at Atelier Casati Milano for made-to-measure sartorial integration.

What is the lifespan of a leather strap for the Boulton H13321812?

A quality leather strap (alligator, shell cordovan or vegetable-tanned calf) can last between 3 and 7 years with regular wear, depending on frequency of use and maintenance. Denser leathers such as alligator and cordovan are more resistant to wear; vegetable-tanned leathers develop patina and require periodic conditioning. Entrusting the strap to professionals like Atelier Casati Milano for maintenance and restoration significantly extends the longevity of the piece.
