Frequently asked questions

What is the lug width of the Archimede Deckwatch UA7929-H1.2?

The Archimede Deckwatch UA7929-H1.2 features a 20-millimetre lug width. This measurement represents the internal distance between the two attachment pins on the case. To verify, measure with a digital calliper the internal transverse distance between the lug supports, ensuring you do not confuse this measurement with the visible width of the strap.

What is the best strap for the Archimede Deckwatch UA7929-H1.2?

The ideal strap depends on intended use and personal aesthetic. For instrumental elegance, we recommend alligator with fine grain in dark brown or black. For nautical contexts, a NATO in grey or navy blue ensures robustness and practical changeability. For those seeking natural patina development over time, vegetable-tanned calf leather represents a compromise between sustainability and durability. For humid or saline environments, vulcanised rubber is the most rational choice.

How do I change the strap on the Archimede Deckwatch UA7929-H1.2?

Strap replacement occurs through removal of the attachment pins that connect the strap to the case. Use a dedicated spring bar tool to compress the lateral pins and extract them from their seats. Position the new pins on the strap edges, then reinsert them into the case seats until definitive click. Ensure the pins are fully locked before wearing the watch.

Can I use an aftermarket strap with the Archimede Deckwatch UA7929-H1.2?

Yes, provided the strap is constructed for 20-millimetre lug width. Always verify specifications with the supplier before purchase. High-quality aftermarket straps, crafted in alligator, shell cordovan, calf leather, or vulcanised rubber, integrate perfectly with the instrumental identity of the Deckwatch. Milano Straps offers compatible 20mm straps ready for dispatch.

How long does a leather strap last on the Archimede Deckwatch UA7929-H1.2?

Durability depends on leather quality and usage patterns. An alligator or shell cordovan strap, subject to regular maintenance (cleaning and conditioning every 4–6 months), lasts 5–8 years. Vegetable-tanned calf, more porous, requires more frequent maintenance (every 3 months) but develops fascinating patina. High-humidity or saline-exposure contexts reduce durability: in such cases, opt for vulcanised rubber, which maintains structural integrity without biological degradation.
