Strap for Ludwig 75 Jahre Grundgesetz

The lug width of the 205.S3 is 18mm, a precise dimension that reflects the proportions of the 35mm tonneau case. This width must be measured perpendicularly between the inner edges of the lugs. Do not confuse with 20mm or 22mm straps, which would create mechanical play and compromise wearing comfort.

Alligator leather with vegetable tanning is the formal and proportionate choice for the Ludwig: the natural grain and patina evolve in harmony with the watch's Bauhaus aesthetic. For everyday variants, compact calf or cotton NATO maintains the minimalist character. Avoid synthetic straps: the rational design of the 205.S3 demands the sincerity of natural materials.

The lugs of the 205.S3 are fitted with screw-on buttons (removable spring bars). Procure a dedicated tool (spring bar tool) or visit a watchmaker. Unscrew the buttons by rotating them anticlockwise, remove the strap, insert the new 18mm strap aligning it perfectly with the lugs, tighten the buttons by rotating clockwise until firm resistance is felt.

Yes, provided the width is measured accurately (±0.5mm tolerance). Many quality aftermarket straps allow complete personalisation of the Ludwig. We recommend verifying that the strap is compatible with the Nomos screw-button lug system, and choosing vegetable-tanned materials for aesthetic coherence.

A vegetable-tanned leather strap, with ordinary maintenance, lasts 3–4 years of daily wear on a watch worn 5–6 days per week. Durability depends on moisture exposure, frequency of use, and care (keep dry, avoid prolonged immersion). Alligator is more resilient than calf. The patina that forms over time is normal and adds aesthetic value.
