Strap for Zürich Weltzeit DXM

The Nomos Glashütte Zürich 805.S34 features a lug width of precisely 20 mm. This measurement is non-negotiable: an 18 mm strap will be loose and unstable, whilst a 22 mm strap will not fit the lug slots. Measure the internal distance between the lugs at the point where they exit the satin-finished steel case to confirm compatibility.

For a timepiece of this aesthetic calibre, we recommend fine-grained alligator or Italian vegetable-tanned calf leather: these materials develop natural patina and mirror the constructive sobriety of the watch. Alternatively, a military-grade NATO or matte FKM rubber offer contemporary practicality whilst maintaining stylistic coherence with the Zürich's minimalist proposition.

Remove the strap using a spring bar tool: insert the flat blade into the slot of the elastic pin, release tension, and the strap will detach. To install a new 20 mm strap, reverse the procedure, ensuring the spring bars are correctly positioned and secure. Take care not to damage the lug finishing during this operation.

Yes, provided the lug width is exactly 20 mm. Premium aftermarket straps (in Italian leather, alligator, or high-quality rubber) are fully compatible and often feature superior finishing and materials compared to OEM options. Always verify technical specifications and source from a specialist supplier that guarantees dimensional accuracy.

A quality leather strap ages rather than deteriorates: with daily wear, it develops natural patina over 3–5 years, then gradually wears at the deployant zone and edges. Alligator or Italian calf lasts 4–7 years before replacement becomes necessary. Durability depends on frequency of use, humidity exposure, and tanning quality. An FKM rubber strap resists 5–8 years whilst maintaining superior structural integrity compared to leather.
