Strap for Boulton Quartz Small Second Yellow Gold / Silver

The Hamilton Boulton H13431553 features an 18mm lug width. This measurement is specific to the Boulton line and represents a deliberate design choice to maintain harmonious proportions on the rectangular case. You can verify the lug width by inserting a digital calliper into the internal hole of the lug: the result will consistently be 18mm.

For the H13431553, we recommend an alligator or vegetable-tanned calf leather strap in brown, burgundy, or black tones. These materials enhance the vintage Art Deco character of the watch and create aesthetic contrast with the stainless steel case. Alternatively, a grey or navy NATO strap offers contemporary practicality whilst maintaining historical coherence.

Strap replacement is straightforward: use a dedicated spring bar tool to compress the lug springs from both sides, then gently extract the old strap. Insert the new strap by aligning one end in the lug first, then compress the opposite lug and allow the spring to click into place. Verify that the strap is secure on both sides before wearing.

Yes, absolutely. Any high-quality artisanal strap with an 18mm lug width is compatible with the H13431553. On milanostraps.it you will find leather, alligator, shell cordovan, NATO and rubber straps, all available in 18mm width and customisable to your preferences.

A high-quality strap with vegetable tanning and artisanal construction typically lasts 3–5 years with daily wear. Durability depends on frequency of use (daily versus occasional), climate, perspiration, and maintenance. Well-cared-for leather—dried after moisture exposure, stored away from excessive heat—can last 7–10 years. The patina that develops over time is part of the charm of a natural leather strap.
