The Heritage

The Nomos Glashütte Autobahn 1301.S2 is a 41mm stainless steel sports-elegant watch with a silver dial, discrete subdials, and a date window at 3 o'clock. It features the automatic DUW 6101 calibre, entirely developed in Glashütte, with rhodium-plated plates and circular jewels. The 20mm lug width is precisely calculated to maintain optical harmony with the case diameter, following principles of balanced proportion between case and strap width.

FAQ

What is the lug width of the Nomos Glashütte Autobahn 1301.S2?

The lug width of the Nomos Glashütte Autobahn 1301.S2 is 20mm, measured at the narrowest point between the two lugs of the case. This measurement is specific and must be respected with precision to ensure correct fitting of any aftermarket strap, avoiding gaps or mounting difficulties.

Which strap is best suited to the Nomos Glashütte Autobahn 1301.S2?

For the Autobahn 1301.S2, we recommend straps in dark brown or black alligator, or vegetable-tanned calf in cognac colour. NATO in grey or black fabric, as well as FKM rubber with fine ribs, combine performance with the austere Bauhaus spirit of the design. Avoid luxury textures or gold finishes that contradict the formal severity of the watch.

How do I change the strap on a 20mm watch?

To change the strap, use a dedicated strap removal tool or a small flat-head screwdriver. Carefully insert the tool into the lateral grooves found at the base of each lug, applying uniform pressure to extract the retaining spring. Repeat on the other side and the strap will detach. Mount the new strap by reversing the procedure, ensuring the spring clicks firmly into position.

Can I fit an aftermarket strap on a Nomos Autobahn 1301.S2?

Yes, provided the strap is compatible with the 20mm lug width and the case lugs are unmodified. Handcrafted straps in alligator leather, calf, military NATO, or technical rubber are fully compatible. Ensure the strap thickness (typically 2.8–3.5mm) does not obstruct mounting on the lugs.

How long does a leather strap last on a watch like the Nomos Autobahn?

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years with daily wear and regular care. Durability depends on environmental humidity, frequency of wear, and maintenance: clean periodically with a damp cloth, avoid direct water exposure, and store in a dry environment. The patina that develops over time is normal and desirable; it signals noble ageing, not deterioration.
