FAQ

What is the lug width of the Nomos Glashütte Zürich 805.S26?

The lug width of the Nomos Glashütte Zürich 805.S26 is 20 mm. This dimension represents the internal space between the case lugs and determines the compatibility of any aftermarket strap. You can verify the exact measurement using a digital calliper across the interior attachment points.

What is the best strap for the Nomos Glashütte Zürich 805.S26?

The ideal strap depends on intended usage. For formal and professional contexts, we recommend an alligator strap with vegetable tanning, which emphasises the linearity of the design without competing visually. For daily wear, a calf leather with satin finish offers versatility and develops a noble patina over time. For those seeking contained sportive character, a NATO strap in silk weave preserves the constructive ethos of the model.

How do you change the strap on the Nomos Glashütte Zürich 805.S26?

The strap is changed by removing the attachment pins (spring bars) from the case lugs. Use a dedicated tool or a flat caseback opener to gently press the spring mechanism of the pins. Apply lever pressure downward until the pin emerges completely from one side, then extract it entirely. Align the new strap with the lug holes and reinsert the pins, ensuring the mechanism clicks securely on both sides.

Which aftermarket straps are compatible with the 805.S26?

All straps with a 20 mm lug width are compatible with the Nomos Glashütte Zürich 805.S26. Milano Straps stocks straps in leather (alligatore, calf, cognac), NATO straps in various textiles, and structured rubber straps. Compatibility is guaranteed by ansa dimension; aesthetic and functional choice remains personal based on usage context.

How long does a leather strap last on a Nomos Glashütte Zürich?

The durability of a leather strap depends on leather quality, frequency of use, and environmental conditions. A calf or alligator strap with vegetable tanning, subject to moderate use in normal conditions, has an average lifespan of 3-5 years. Vegetable-tanned leather adapts to the wrist over time, developing a patina that amplifies aesthetic value. Prolonged exposure to humidity, excessive heat, or direct sunlight may reduce this lifespan.
