Ludwig 234.S3— lug 19mm

The Nomos Glashütte Ludwig 234.S3 features a lug width of 19 mm. This measurement refers to the internal distance between the straight lugs on the case where the strap is inserted. It is essential to verify this specification when purchasing aftermarket straps to ensure perfect mechanical compatibility.

For the Ludwig 234.S3, we recommend a strap in black alligator or vegetable-tanned calf leather. Alligator provides maximum minimalist elegance with natural texture; vegetable-tanned calf develops patina more rapidly over time. Both honour the German essential design ethos of the model.

Remove the strap using a spring bar tool to extract the two elastic pins that secure it to the lugs. Insert the tool into the small groove, retract, and the strap detaches cleanly. When reassembling, ensure the pins are perfectly seated to avoid mechanical stress on the stainless steel lugs.

Yes, any strap with a 19mm lug width is compatible with the 234.S3. We recommend artisanal leather, rubber or textile straps manufactured to this exact specification. Always verify that the declared lug width matches 19mm to ensure compatibility without mechanical slack.

Durability depends on material and usage intensity. A vegetable-tanned calf strap averages 3–4 years of daily wear; alligator reaches 4–5 years. Rubber resists 5–7 years. Humidity exposure, sunlight and strap rotation frequency significantly influence longevity. Regular maintenance (balm every six months) considerably extends lifespan.
