Nomos Glashütte
Zürich 805.S3— lug 20mm

The Nomos Glashütte Zürich 805.S3 features a 20 mm lug width. This measurement represents the distance between the two spring bar attachment points on the case where the strap is fitted. Verifying this specification is essential before purchasing an aftermarket strap to ensure perfect compatibility with your timepiece.

For the Nomos Zürich 805.S3, an alligator strap with vegetable tanning is recommended, as it complements the rationalist aesthetic of the watch. Alternative choices include vegetable-tanned calf leather for a restrained appearance, NATO fabric straps for casual versatility, or FKM rubber for sports environments. Selection depends on intended use and personal preference.

The strap is changed using a spring bar removal tool or delicate extraction pin. Insert the tool into the access hole beneath the lug, press the internal spring upward to release the attachment ring, then remove the strap. This operation requires precision to avoid damaging the case. If uncertain, consult a professional watchmaker.

Yes, you may use quality artisanal aftermarket straps provided they respect the 20 mm lug width and compatible attachment system (spring bar loops). Handcrafted straps from Italian makers such as Milano Straps ensure construction quality and finishing consistent with Nomos horological excellence, allowing personalisation without compromise.

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3-5 years with daily wear, depending on frequency of use, sun exposure, and humidity levels. Longevity increases with regular maintenance (cleaning, conditioning). At Milano Straps, artisanal straps are engineered to age gracefully, developing patina and character over time.
