Nomos Glashütte
Zürich 805.AWC— lug 20mm

The lug width of the Nomos Glashütte Zürich 805.AWC is 20.00 mm. This measurement is precise and corresponds to the case construction parameter: it should be measured from inside to inside of the lug shoulder at the point where the cone of narrowing towards the strap passage begins.

The best strap depends on intended use and aesthetic preference. For formal elegance we recommend vegetable-tanned alligator or English calf; for daily practicality, a polyamide NATO or vulcanised rubber strap. The brushed stainless steel case communicates particularly well with structured-grain leathers.

Strap replacement requires no specialised tools. Position the watch with lugs facing upward, locate the spring bars connecting the strap to the case, gently push the bar from one side using a small screwdriver or dedicated tool, remove the old strap, insert the new one by aligning the lug holes with the spring bars and push until it locks.

Yes, the 805.AWC is fully compatible with any aftermarket strap featuring a 20 mm lug width. Always verify the construction specification with the vendor before purchase, and ensure the strap is designed for lug shoulders consistent with case geometry.

Leather strap lifespan depends on frequency of use, tanning method, and environmental conditions. A vegetable-tanned calf strap, with moderate daily use, typically lasts 3-5 years before replacement is required. Vegetable-tanned alligator offers superior longevity (5-7 years). The patina developing on the leather over time narrates the watch's usage history.
