Strap for DeckWatch Bronze / Silver / Black Leather

The Archimede Deckwatch UA7929-H1.1-BR features a standardised lug width of 20mm. This measurement represents the distance between the internal ends of the case where the strap is inserted. To verify strap compatibility, measure this distance: if it corresponds to 20mm, the strap will fit perfectly into the case lugs without play or shifting.

Strap selection depends on usage and aesthetic preference. To enhance the patinated bronze, we recommend an alligator strap in black or a dark vegetable-tanned calf leather. To preserve the nautical identity of the Deckwatch, a grey or brown NATO is ideal. A black rubber strap offers maximum practicality and water resistance. All these materials are available in 20mm at milanostraps.it.

Changing the strap is straightforward: remove the old strap by extracting the lateral case pins using a spring bar tool. Insert the new 20mm strap by snapping the pins into the holes. Ensure the strap is positioned symmetrically on both sides of the case and that the passants adhere firmly to the case without leaving empty spaces.

Yes, perfectly. Since the lug width is standardised at 20mm, any quality artisanal strap with a 20mm measurement is compatible with this model. We recommend straps made from premium materials (alligator, quality calf leather, authentic military NATO) to maintain aesthetic coherence with the rigorous construction of the Deckwatch.

A quality leather strap (alligator, shell cordovan, calf) typically lasts 3-5 years with moderate use (5-6 days weekly). Factors such as humidity, sun exposure, frequency of use and maintenance affect longevity. A vegetable-tanned strap tends to age better, developing patina. NATO and rubber straps have a longer lifespan (5-8 years) due to their more robust nature.
