Frequently asked questions

Which strap type is recommended for the Hamilton Boulton H13321861?

For the Boulton H13321861, we recommend a vegetable-tanned calf leather strap, which emphasises the understated elegance of the rectangular case. Alternatively, an <a href="/pages/termine-glossario/alligatore">alligator</a> strap creates aesthetic synergy with the watch's geometric language, whilst a cotton twill NATO strap offers formal versatility. For sportier use, a fine-grained FKM rubber maintains stylistic integrity.

How do you change the strap on the Hamilton Boulton H13321861?

Position the watch on a soft surface with the dial facing down. Using a spring bar tool, press the small spring located inside the lower lug to release the pin pressure. Once released, the strap will detach easily. Repeat the operation from the other side. To install the new strap, align the pin with the lug hole, press lightly and use the tool to click the opposite side until fully inserted.

How long does a leather strap last on the Hamilton Boulton H13321861?

The lifespan of a leather strap depends on daily wear, ambient humidity and tanning method. A vegetable-tanned leather strap worn daily lasts approximately 3-5 years before requiring replacement, although patina continues to develop, enriching the aesthetic over time. Regular cleaning and occasional leather balm application extend useful life. Synthetic or FKM rubber straps offer superior durability, up to 7-10 years.
