Frequently asked questions

What is the lug width of the Archimede 1950'S UA8069BM-A1.1?

The lug width of the Archimede 1950'S UA8069BM-A1.1 is 20mm. This measurement is the standard for this model and determines compatibility with all aftermarket straps. The lug width is measured between the inner shoulders of the case at the spring bar attachment points.

Which strap is recommended for the Archimede 1950'S?

For the Archimede 1950'S UA8069BM-A1.1, vegetable-tanned alligator or calf leather straps are recommended for a formal classic aesthetic, NATO canvas straps offer a sporty-casual style, and FKM rubber straps suit aquatic environments or recreational activities. Your choice depends on intended use and desired colour contrast with the dial.

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

To change the strap, use a spring bar tool or consult a professional watchmaker. Position the tool beneath the spring bar, apply gentle pressure to compress the internal spring, extract the bar, and remove the old strap. Reverse the procedure to install the new strap. For valuable watches like the Archimede, professional servicing is recommended.

Are there compatible 20mm aftermarket straps available for this model?

Yes, milanostraps.it offers a comprehensive selection of artisanal 20mm straps compatible with the Archimede 1950'S UA8069BM-A1.1. Straps are crafted from Italian leather, technical materials and fine fabrics, customisable according to your colour and finish preferences. Compatibility is guaranteed by the standardised lug width specification.

What is the average lifespan of a leather strap before replacement is needed?

A quality leather strap, subjected to daily wear and regular maintenance (occasional cleaning and conditioning with natural balms), typically lasts 3-5 years. Straps manufactured with vegetable tanning tend to age exceptionally well, developing a desirable patina, whilst replacement becomes necessary when leather loses elasticity or stitching deteriorates. Rubber straps, if protected from prolonged UV exposure, maintain functionality and appearance for 5-7 years.
