Strap for Autobahn Director's Cut Limited Edition A9

The lug width of the Nomos Glashütte Autobahn 1301.S3 is 20 millimetres. This measurement represents the linear distance between the spring bars that attach the strap to the case lugs. The 20mm width is consistent on both the crown side and the opposite side, ensuring compatibility with the entire catalogue of 20mm aftermarket straps.

The choice depends on intended use. For daily elegance, we recommend vegetable-tanned calf leather in cognac or black tonalities, which amplifies the Bauhaus purity of the case. For sporty versatility, NATO in cotton or natural linen. For maximum sophistication, shell cordovan in burgundy develops extraordinary patina over time. FKM rubber is ideal for humid climates or outdoor activities.

Remove the original strap using a spring bar tool. Position the compressor on the spring, insert the tool into the lateral slot and depress gently. The spring bar will disengage from the case lug. Reverse the procedure with the new strap, ensuring the bars are fully inserted and the spring is in the safety position. If you lack the tool, consult a qualified watchmaker.

Any strap with a 20mm lug width is compatible with the 1301.S3. The market offers numerous artisanal options: Italian leather, shell cordovan, NATO in various weaves, vulcanised rubber, waxed canvas. MilanoStraps curates a refined selection of 20mm leather straps, vegetable-tanned and customisable according to colour and buckle preferences.

Durability depends on material, climate, and frequency of use. A quality vegetable-tanned calf strap on a 41mm model like the 1301.S3 typically lasts 3–5 years under regular wear. Shell cordovan, being denser, can exceed 7–8 years. Cotton NATO lasts 4–6 years. Humidity, perspiration, and prolonged sun exposure accelerate wear. Periodic maintenance—gentle cleaning, leather conditioning—significantly extends lifespan.
