Strap for Max Bill Automatic Silver No-Date

The Junghans Max Bill 027/3500.00 has a lug width of 20 millimetres, measured internally between the lugs. This is a non-standard measurement, almost exclusive to the Max Bill family. To verify correctly, place a metal ruler inside the lugs, without forcing, and read the value between the contact points of the spring bars.

European vegetable-tanned calf leather is the ideal choice: the natural patina that develops over time harmonises with the minimalist philosophy of the dial. Anthracite grey alligator offers graphic sobriety. Silvered shell cordovan creates introspective depth. Natural NATO provides a coherent sports solution. Black rubber maintains formal purity. Every option must avoid embroidery and decorations: the Max Bill refuses them.

Remove the old strap using a spring bar tool or gentle lateral pressure to free the bars from the lugs. Insert the new 20mm strap pins into the lug housings and verify they click fully. If the strap has a deployante, ensure it faces the case back. Test security by pulling gently: it should not detach. If preferred, Atelier Casati Milano offers replacement services with sartorial precision.

Yes, provided they respect the 20mm lug width specification. Always verify that the strap is specifically designed for this width: standard 18mm or 22mm straps will not fit correctly. MilanoStraps artisanal straps are custom-built for the 027/3500.00 and guarantee geometric and constructive compatibility. Avoid budget-tier uncertified straps: the Max Bill deserves precision.

A quality calf strap, vegetable-tanned, lasts 3–5 years in daily wear, developing patina that amplifies character. Shell cordovan reaches 7–10 years. Durability depends on perspiration, humidity exposure and maintenance. Vegetable-tanned leather requires occasional cleaning with a soft cloth. MilanoStraps artisanal straps use European leathers selected for longevity and beautiful ageing.
