FAQ

What is the lug width of the Nomos Glashütte Autobahn 1301.S1?

The Nomos Glashütte Autobahn 1301.S1 features a lug width of 20mm, measured as the space between the lugs of the 41mm case. This dimension is the industry standard for watches in this size category and ensures optimal visual proportion and ergonomic comfort on wrists of any circumference.

What is the best strap choice for the Autobahn 1301.S1?

The optimal strap for the 1301.S1 is crafted from alligator leather with vegetable tanning, in dark brown or black. This selection respects the Bauhaus aesthetic of the case and the matte black lacquered dial. Alternatively, smooth calf leather in tobacco brown or FKM rubber in grey or black enhance versatility whilst maintaining design coherence.

How do you change the strap on the Nomos Glashütte Autobahn 1301.S1?

Remove the strap by using a spring bar tool to disengage the two lug bars (spring bars) anchoring the strap to the case. Insert the flat blade of the tool into the small aperture beneath each lug, applying gentle lever pressure to free the bars. Extract the old strap and insert the new one, securing the bars at opposing ends. The procedure requires approximately 3–5 minutes and demands no technical expertise.

Are aftermarket straps compatible with the Nomos Glashütte Autobahn 1301.S1?

Yes, any strap with a 20mm lug width is physically compatible. However, aesthetic coherence is paramount: artisanal leather straps (alligator, calf, shell cordovan) or technical rubber maintain visual and conceptual alignment with the case. Avoid NATO straps or inexpensive synthetic fabrics, which contradict the Bauhaus restraint of the design.

What is the lifespan of a leather strap on the Nomos Glashütte Autobahn 1301.S1?

A high-quality leather strap (alligator or vegetable-tanned calf) retains structural integrity for 3–5 years of daily wear. Durability depends on frequency of use, exposure to moisture, and periodic maintenance (gentle cleaning with a damp cloth and conditioning with natural balms). The patina that emerges over time is a hallmark of authentic craftsmanship, not deterioration.
