Strap for 1950-1 Stainless Steel / Black / Black Leather

The lug width of the Archimede 1950'S UA8069-A2.1 is 20mm. This is measured internally between the spring bar pins: the distance must correspond exactly to 20mm to ensure compatibility and aesthetic harmony with the 39mm case diameter.

For the minimalist design of the 1950'S, we recommend a black matte alligator or vegetable-tanned calf leather, which maintain the austere aesthetic. A dark grey NATO offers an informal alternative. Avoid light or coloured straps that would compete with the brushed steel case.

Use a dedicated tool (spring bar tool) to remove the pins from the internal spring. Position the tool perpendicular to the spring, gently push towards the centre of the case to compress the spring, then extract the pin. Repeat on both lugs. Insert the new strap in reverse direction.

Yes, any strap with a 20mm lug width is compatible. Verify that the internal width between the pins corresponds exactly to 20mm. MilanoStraps offers handcrafted straps in leather, rubber and fabric, customisable to suit your style.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily use, provided periodic maintenance (drying after humidity exposure, annual conditioning). Occasional use extends the lifespan to 8-10 years. Vulcanised FKM rubber resists 5-7 years with minimal ageing.
