Frequently asked questions

What is the lug width of the Archimede 1950'S UA8069-A2.2?

The lug width of this reference is 20mm, an atypical configuration requiring bespoke-crafted straps. Measurement is performed by positioning a calliper between the internal metal terminals of the case lugs, ensuring precise edge-to-edge measurement of the attachment section.

Which strap is most suitable for the Archimede 1950'S UA8069-A2.2?

For this reference, we recommend alligator in grey or brown tones for formal occasions, as the natural pattern of the leather dialogues elegantly with the satinised finish of the steel. Alternatively, vegetable-tanned calf represents the versatile daily choice, whilst technical NATO straps are ideal for conscious instrumental use.

How do you change a strap on a watch with 20mm lugs?

Strap change requires dedicated tools: a spring bar tool to extract the elastic pins from the seats. Position the watch on a stable surface, carefully insert the tool into the groove of the original strap terminal, compress the spring, and withdraw the strap. Repeat on the opposite end. Install the new strap following the reverse operation, verifying that the pins engage firmly in the seats.

Are there aftermarket straps compatible with the 20mm lug width?

Yes, milanostraps.it offers a complete collection of 20mm straps, handcrafted and available online. The range comprises alligator leather, calf, technical NATO straps and FKM rubber. All straps are dispatched ready and customisable according to colour preference and buckle finish.

How long does a leather strap last on a daily-use watch like the Archimede 1950'S?

The longevity of a leather strap depends on usage frequency, environmental conditions and tanning quality. An artisanal-quality alligator or vegetable-tanned calf strap, subject to rotation with other straps (avoiding continuous wear), maintains structural integrity between 3 and 5 years. Humidity, perspiration and prolonged sun exposure reduce this timeline; ventilation and periodic cleaning with soft cloth extend it significantly.
