Frequently asked questions

What is the lug width of the Archimede Deckwatch UA7952-H2.1?

The lug width of the Archimede Deckwatch UA7952-H2.1 is 20mm. This measurement is specific to this model and should be verified by measuring the distance between the two lug holes. It is not the standard 22mm width, so it is essential to confirm compatibility before purchasing an aftermarket strap. Milano Straps offers a complete collection of straps in various materials designed precisely for this width.

What is the best strap for the Archimede Deckwatch UA7952-H2.1?

The best strap depends on intended use. For a classical-formal context, we recommend vintage alligator in tobacco brown tones or vegetable-tanned calf that evolves naturally over time. For a more technical-sports approach, NATO in dark blue or military green valorises the instrumental vocation of the Deckwatch. For humid or aquatic environments, black satin FKM rubber ensures reliability without aesthetic compromise. The key is choosing materials that respect the minimalist philosophy of German design.

How do you change the strap on the Archimede Deckwatch UA7952-H2.1?

Strap replacement on the UA7952-H2.1 is performed using spring bars, small metal pins that pass through the lug holes of the watch case. Using a dedicated removal tool, gently press toward the centre to release the spring bar tension, then slide the old strap outward. Insert the new strap by aligning the holes with the spring bars and ensure the bars are fully inserted and locked. The operation requires care to avoid scratching the case.

Which aftermarket straps are compatible with the Archimede Deckwatch UA7952-H2.1?

All straps manufactured for the 20mm lug width are compatible with the UA7952-H2.1, provided the spring bars are correctly dimensioned. On Milano Straps, the dedicated 20mm collection includes alligator, vegetable-tanned calf, double-layer canvas NATO, FKM rubber and natural rubber straps. Each strap is produced with attachments precisely calibrated for this width. Always verify that the seller explicitly specifies 20mm compatibility.

How long does a leather strap last on the Archimede Deckwatch UA7952-H2.1?

The lifespan of a leather strap depends on the tanning method and usage. A quality vintage alligator or vegetable-tanned calf strap can last 4-7 years under normal daily wear conditions, accounting for natural fibre degradation. Humidity, perspiration and sun exposure accelerate ageing. A double-layer canvas NATO strap typically lasts 6-10 years. FKM rubber maintains functional properties for 8-12 years before stiffening. We recommend regularly checking leather integrity and rotating multiple straps to distribute wear.
