The 1950'S UA8069-A1.2, seen from the bench

The Archimede 1950'S UA8069-A1.2 is a 39mm stainless steel watch embodying German watchmaking philosophy through functional essentiality. It features a Miyota quartz caliber 9015 movement with hours, minutes, seconds, and date display. The 20mm lug width accommodates versatile strap options including leather, fabric, rubber, and metal. The stainless steel case develops natural patina over time, prioritizing substance over appearance.

Frequently asked questions

What is the lug width of the Archimede 1950'S UA8069-A1.2?

The lug width of the UA8069-A1.2 model is 20mm. This measurement refers to the distance between the two spring bars that attach the strap to the case. It is the classical standard size for men's medium-sized wristwatches, compatible with a wide range of handcrafted leather, fabric, and rubber straps.

What is the best strap for the Archimede 1950'S UA8069-A1.2?

The choice of strap depends on use and aesthetic preference. For formal occasions, an alligator or shell cordovan strap with vegetable tanning offers longevity and natural ageing. For daily wear, English or German calf leather guarantees durability and comfort. For a sober sporty style, we recommend NATO straps in cotton or vulcanised rubber, solutions that emphasise the model's constructive severity.

How do I change the strap on my Archimede 1950'S?

The strap is replaced using the spring bars. With a dedicated tool (strap changer), gently push the lateral spring bar until the strap end is released from its seat. Repeat for the other bar. Insert the new strap, aligning the holes with the spring bar ends and push until it clicks into place. Verify that the strap is equidistant between the lugs. If uncertain, consult a professional watchmaker.

Is an aftermarket 20mm strap compatible with the UA8069-A1.2?

Yes, any strap with a 20mm lug width is compatible with the UA8069-A1.2 model. However, verify that the strap thickness is proportionate to the 39mm case: excessively thick straps may create visual discord, whilst thin straps in fine leather maintain the elegance of classical proportions. The handcrafted straps from milanostraps.it are calibrated to this dimensional standard.

What is the lifespan of a leather strap for this watch?

A high-quality leather strap (alligator, shell cordovan, calf with vegetable tanning) typically lasts 3-5 years with moderate daily use. Longevity depends on frequency of use, climate (humidity accelerates deterioration), exposure to aggressive substances and maintenance. Periodically apply neutral balm, avoid prolonged contact with water and store in a dry environment. Noble material straps age positively, developing patina and richer colouration over time.
