The Heritage

The Nomos Glashütte Autobahn Neomatik 41 is a manual-wind chronograph from the Autobahn collection, housing the proprietary DUW 6101 caliber with hours, minutes, small seconds, and date display. The stainless steel case measures 41 mm in diameter with a 20 mm lug width, reflecting classic proportions of 1960s-70s German sports chronographs. The watch features an anti-reflective sapphire crystal, transparent caseback, and water resistance to 10 atmospheres suitable for daily wear and pool immersion.

FAQ

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

The lug width of the Nomos Glashütte Autobahn 1301 is 20 millimetres. This measurement is taken as the internal distance between the two case lugs, excluding the width of the metal spring bars. A 20 mm lug width represents the proportional balance point for a 41 mm case diameter, ensuring comfort during wear and aesthetic elegance on average-width wrists.

Which strap do you recommend for the Autobahn 1301?

For the Nomos Autobahn 1301, we prioritise a strap in alligator leather with vegetable tanning, which highlights the contrast between the natural grain of the leather and the sharp geometry of the case. Alternatively, a vegetable-tanned calf leather at 1.4 millimetres thickness offers comfort and predictable patina development. For sporting use, a vulcanised rubber strap maintains the functional coherence of the Bauhaus design. A ballistic nylon NATO strap represents a modern and versatile choice, although it slightly diminishes the aesthetic refinement.

How do I change the strap on the Autobahn 1301?

The Autobahn 1301 features straight lugs measuring 20 millimetres, easily accessible by removing the strap with soft felt pads to protect the case. Position the watch on a cloth, then use a spring bar removal tool to gently compress the internal spring and extract it from the lugs. Proceed carefully to avoid case scratches. Insert the new strap into the lugs and verify correct attachment before wearing the watch. The procedure takes less than two minutes, even for careful beginners.

Are aftermarket straps compatible with the Nomos Autobahn 1301?

Yes, any strap with a 20 millimetre lug width is mechanically compatible with the Autobahn 1301. However, we recommend selecting straps of constructive quality matching the watch: a poorly made leather strap compromises both the visual and tactile experience. Artisanal straps in alligator, vegetable-tanned calf, or vulcanised rubber from reliable manufacturers maintain the aesthetic and functional coherence of the German timepiece.

How long does a leather strap last on the Autobahn 1301?

The lifespan of a leather strap depends on tanning quality, daily use intensity, and maintenance. An artisanal alligator strap with vegetable tanning offers 4–6 years of intense daily wear before structural failure, thanks to the natural density of alligator leather. A softer calf leather lasts 2–4 years under the same conditions. Longevity increases significantly with proper care: avoid prolonged water immersion (unless treated), keep the strap dry overnight, and periodically apply neutral balm. A vulcanised rubber strap lasts 5–7 years before showing fragility.
