Strap for 1950-2 Stainless Steel / Silver / Mesh

The lug width (lug-to-lug distance) of the Archimede 1950's UA8068BMP-A1.1 is 20 millimetres. This measurement represents the distance between the two metal pins situated at 12 o'clock and 6 o'clock on the case. It is essential to verify this dimension before purchasing an aftermarket strap, as an incompatible lug width could damage the pins or create excessive movement during wear.

The ideal strap depends on intended usage. For formal and office contexts, we recommend dark brown alligator with vegetable tanning: it enhances the Bauhaus geometry of the watch and develops natural patina over time. For daily versatility, cognac-coloured calf leather with satin finishing maintains visual proportion. For sport or humid environments, a cerated canvas NATO or FKM rubber strap offers practicality without aesthetic compromise. Burgundy shell cordovan represents the ultimate balance: craftsmanship, predictable ageing, and elegance.

Strap replacement requires a dedicated tool: the spring bar tool. Procedure: 1) position the watch on a stable surface with the strap facing upward; 2) insert the spring bar tool tip under the metal lug pin, pushing downward to compress the internal spring; 3) extract the pin from the case; 4) repeat for the second pin; 5) align the new strap holes with the lugs and insert; 6) reinsert the pins until a subtle click is felt. Avoid forcing: a soft click indicates correct positioning.

Yes, any strap with a 20-millimetre lug width is technically compatible with the Archimede 1950's UA8068BMP-A1.1. However, the construction quality of the strap—leather thickness, edge finishing, leather suppleness—determines durability and aesthetic harmony. We recommend straps manufactured with vegetable-tanned leather or shell cordovan, avoiding synthetic or chrome-plated leather that ages poorly and compromises the watch's appearance.

The lifespan of a leather strap depends on tanning method and usage frequency. A vegetable-tanned leather strap, if worn daily, typically lasts 18–24 months before visible weakening. Shell cordovan, thanks to denser fibre structure, can extend durability to 30–36 months. A strap worn occasionally (2–3 days weekly) can last twice as long. Factors reducing lifespan: prolonged water exposure, acidic perspiration, repeated bending on the same point. The natural patina that develops does not indicate wear but rather aesthetic enrichment of the material.
