FAQ
What is the lug width of the Archimede 1950'S UA8069BM-A2.1?
The Archimede 1950'S UA8069BM-A2.1 features 20mm lugs. This dimension is determined by the geometry of the 39mm case and represents a less common standard in contemporary watchmaking. Compatible straps must have internally dimensioned bars precisely calibrated to 20mm to ensure stable attachment without lateral play.
Which strap do you recommend for the Archimede 1950'S UA8069BM-A2.1?
For the stainless steel case of this model, we recommend a strap in alligator or shell cordovan in cognac brown, whisky, or smoked grey tones. These material and chromatic choices amplify the formal geometry of the case. Alternatively, a NATO strap in charcoal grey linen maintains aesthetic severity. For sports use, structured FKM rubber offers superior practicality.
How do I change the strap on the Archimede 1950'S UA8069BM-A2.1?
To change the strap, you will need a spring bar tool or a small flathead screwdriver. Position the watch securely, insert the tool into the hole beneath the lug, apply gentle pressure to compress the internal spring, and slide the lug outward. Repeat the procedure from the other side. Insert the new strap by seating the bars on the lugs and verify that it is firmly attached before wearing.
Which aftermarket straps are compatible with the UA8069BM-A2.1?
Any strap with a 20mm internal bar opening is compatible. At milanostraps.it you will find a complete selection of artisanal leather, military NATO, and technical rubber, all available in the 20mm size. Compatibility is guaranteed by the internal dimensioning of the side bars, regardless of the original strap brand.
What is the lifespan of a leather strap on the Archimede 1950'S UA8069BM-A2.1?
A high-quality leather strap with vegetable tanning (alligator, shell cordovan, calf) has an average lifespan of 3-5 years with daily use, considering wear frequency of 5-6 days per week. Longevity depends on climate, humidity, cleaning frequency, and storage conditions. Leather straps develop a natural patina that enriches their aesthetics over time. After the first 18 months of use, maintenance every 12-24 months is advisable to preserve flexibility and prevent cracking.
