Archimede
Klassik UA7969-A3.3— lug 20mm

The lug width is 20mm, measured correctly from the internal extremities of the spring bar pins. This width represents Archimede's intentional proportional compromise to maintain visual balance on the 39mm case. Any 20mm strap installs without mechanical adaptation.

To enhance the minimalist construction philosophy, we recommend dark brown alligator or burgundy shell cordovan: both develop natural patina over time, creating tactile history that dialogues with the case's rigorous geometry. For daily wear, vegetable-tanned calf leather offers robustness and harmonious ageing.

The Klassik features fixed lugs without integrated spring bars. Strap change requires a dedicated tool (spring bar tool) to compress the springs and extract them laterally from the pins. Delicate operation: we recommend entrusting a specialist workshop for the first time, or consulting specific video tutorials. Avoid hammers or brute force that damage case finishing.

Yes. Any strap with 20mm lug width is compatible. Milanostraps offers a dedicated collection at this width: artisanal leather, NATO, technical rubber, all ready for dispatch and customisable. Compatibility is guaranteed by international standardisation.

A high-quality leather strap (alligator, shell cordovan, vegetable-tanned calf) has an average lifespan of 3-5 years with daily wear, extendable to 7-10 years with regular maintenance: periodic hydration, gentle cleaning, air drying. Patina becomes more beautiful with ageing, not compromising functionality. Rotating between multiple straps significantly extends useful life.
