FAQ
What is the lug width of the Archimede Klassik UA7969-A3.10?
The Archimede Klassik UA7969-A3.10 features a 20.00mm lug width. This specific measurement was chosen to maintain harmonious proportions with the 39mm case. Measurement should be made using a digital calliper perpendicular to the case lugs and parallel to the crown for millimetre-perfect accuracy.
Which strap is recommended for the Archimede Klassik?
The ideal strap depends on intended use. For formal contexts, we recommend vegetable-tanned alligator or vegetable-tanned calf leather. For versatile daily wear, NATO nylon straps offer practicality without aesthetic compromise. FKM rubber is perfect for sports activities, maintaining Archimede's minimalist design coherence.
How do I change the strap on the Archimede Klassik UA7969-A3.10?
The Klassik uses standard spring bar attachments in 20mm lugs. To replace, obtain a spring bar tool and gently insert the tip into the lateral hole of each lug to compress the internal spring. Once the old strap is extracted, insert the new one in the same manner. Work carefully to avoid scratching the stainless steel case.
Are aftermarket straps compatible with the UA7969-A3.10?
Yes, provided they are specifically dimensioned for 20mm lug width. Not all universal straps fit this particular configuration perfectly. We recommend verifying technical specifications carefully before purchase. On milanostraps.it you will find a curated collection of artisanal straps already tested for compatibility with this measurement.
How long does a leather strap last on the Archimede Klassik?
Durability depends on material and intensity of use. A quality vegetable-tanned alligator or shell cordovan strap, with regular maintenance, can last 5-10 years or more. Calf leather is generally less resistant (3-5 years). Protecting the strap from standing water, avoiding prolonged direct sunlight, and occasionally applying neutral balm significantly extends service life.
