Nomos Glashütte
Ludwig 235— lug 19mm

The lug width of the Nomos Glashütte Ludwig 235 is precisely 19 millimetres. This measurement must be respected exactly to ensure strap compatibility with the case lugs. A 20mm strap would be too wide, whilst an 18mm strap would not fit correctly.

The Ludwig 235, given its minimalist Bauhaus philosophy, pairs ideally with straps crafted from alligator or vegetable-tanned calf leather. For the 37.50mm case, natural tones such as taupe brown, caramel, or grey are recommended. A NATO canvas strap offers versatility for informal contexts. Avoid bright colours that would contradict the watch's sober aesthetic.

To change the strap, use a spring bar tool to remove the metal clips securing the strap to the lugs. Insert the tool into the small lateral slot of the lug, push inward to release the spring, and slide the strap out. To install the new strap, reverse the procedure, ensuring the spring is fully seated in the lug.

Yes, quality aftermarket straps are fully compatible with the Ludwig 235, provided they feature a 19mm lug width and are crafted by specialised artisans. High-grade vegetable-tanned leather, alligator, or NATO canvas straps maintain aesthetic coherence with the watch's minimalist design and allow complete personalisation of the look.

A quality artisan-crafted leather strap, when worn daily, typically lasts 3-5 years before requiring replacement. Vegetable-tanned leather develops a patina that improves over time owing to the natural properties of tannin. Occasional or rotational use with other straps significantly extends durability. Regular maintenance with leather-specific creams prolongs lifespan considerably.
