FAQ
What is the exact lug width of the Nomos Glashütte Zürich 805?
The lug width of the Nomos Glashütte Zürich 805 is 20 mm. This measurement is taken between the inner shoulders of the lugs, excluding the terminals. To ensure complete compatibility, we recommend verifying with a digital calliper before purchasing an aftermarket strap, as variations of even ±0.5 mm can compromise the fit.
Which strap pairs best with the Zürich 805?
For the Zürich 805, we recommend vegetable-tanned alligator leather (black or deep blue) for formal contexts, or Italian calf with a patinated finish for daily wear. A NATO strap in grey-talc cotton offers a highly versatile casual aesthetic. Your choice should reflect context: the minimalism of the asymmetric white dial is enhanced by materials that don't compete visually, prioritising simplicity and readability.
How do you change the strap on a Nomos Glashütte Zürich 805?
To change the strap: 1) Obtain a spring bar tool with flat ends. 2) Place the watch on a soft cloth. 3) Insert the tool's tip into the small lateral hole of the lug, pushing gently outward to compress the internal spring. 4) Once the spring yields, carefully extract the pin. 5) Repeat for both lugs. 6) Mount the new strap by aligning the holes with the lug terminals, inserting the pin and ensuring it clicks into position securely.
Is an aftermarket 20mm strap truly compatible with the 805?
Yes, any strap with a 20mm lug width is compatible with the Nomos Glashütte Zürich 805. However, we recommend selecting leather with a thickness between 1.4 and 1.8 mm to ensure optimal fit beneath the lugs. Straps exceeding 2 mm thickness may create uneven pressure, whilst those under 1.2 mm may shift. The quality of vegetable tanning and buckle finish further influence the final aesthetic result.
How long does a leather strap last with daily wear?
A quality calf leather strap with vegetable tanning, worn daily, has a useful lifespan of 3–5 years before replacement becomes necessary. Natural patination contributes to an interesting aesthetic patina within the first 12–18 months. Alligator leather, due to its denser fibrous structure, may last 5–7 years. A pure cotton NATO strap, subject to regular washing, maintains performance for 2–3 years. Longevity depends on frequency of wear, climatic conditions and maintenance: protect from excessive humidity, prolonged perspiration and direct heat sources.
