Ludwig 234— lug 19mm

The Nomos Glashütte Ludwig 234 features a lug width of 19mm. This measurement refers to the space between the metal pins that pass through the case at 3 and 9 o'clock. It is the standard for cases with a 37.50mm diameter and ensures optically balanced proportions in relation to the case geometry.

For the Ludwig 234, we recommend natural alligator with vegetable tanning or high-quality European calf leather. Both materials develop an elegant patina over time that dialogues perfectly with the Bauhaus simplicity of the dial. For those who change straps frequently, poised grey NATO in polyamide maintains aesthetic equilibrium without functional compromise.

Strap replacement requires a dedicated tool for spring bar extraction (spring bar tool). Position the watch on a stable surface with the caseback facing upward. Insert the tool tip into the small lateral hole of the spring bar, apply gentle pressure and the pin will retract, allowing you to remove the lug. For the new strap, align the upper end with the pin and press until you hear the engagement click. If you lack experience, contact Casati Milano for professional strap-change service.

Yes, provided that the lug width is exactly 19mm and the diameter of the contact zone with the case is properly calibrated. All Milan Straps lug width 19mm straps have been mechanically verified to ensure total compatibility with the Ludwig 234 and other models of the same standard. A superior quality artisanal strap significantly improves the overall tactile perception of the watch.

Longevity depends on material and usage. An alligator with vegetable tanning typically lasts 3-5 years with regular rotation. European calf leather has similar durability but develops a more pronounced patina. Shell cordovan, if chosen, reaches 7-10 years. Primary wear localises at the closure holes and in the contact zone with the case. Rotating among multiple straps significantly extends the life of each.
