The Orion 326, seen from the bench

The Nomos Glashütte Orion 326 is a contemporary interpretation of Bauhaus principles applied to watchmaking. The 32.80 mm stainless steel case features a white dial with baton indices and a visible Alpha caliber movement through the open case back. The 17 mm lug width is critical to the watch's visual symmetry and proportional harmony. The Alpha caliber is a manual-winding movement with hours, minutes, and small seconds. Water resistance reaches 50 meters, suitable for daily wear. Lug width of 17 mm must be precisely measured between the lugs themselves to maintain the watch's design integrity and aesthetic balance.

Frequently asked questions

What is the exact lug width of the Nomos Glashütte Orion 326?

The lug width (ansa) of the Nomos Glashütte Orion 326 is 17 mm. This dimension corresponds to the case width and ensures the proportional balance of the design. Always measure between the pins perpendicularly to the case, excluding the pin shoulders.

Which strap material is best suited for the Nomos Orion 326?

A vegetable-tanned calf leather in neutral tones (cognac brown, black, pearl grey) is the ideal choice. For greater durability, aged shell cordovan develops a deep patina over time. NATO straps offer daily practicality, whilst FKM rubber guarantees longevity for intensive use.

How do you change the strap on the Nomos Orion 326?

Position the watch on a stable surface and use a spring bar tool to remove the pins. Press the pin downward to release one end, then withdraw the worn strap. Insert the new strap, aligning the holes with the pins, and reposition the pin into the groove.

Are aftermarket straps compatible with the Nomos Orion 326?

Yes, all straps with 17 mm lug width are compatible. Ensure the strap thickness does not exceed 3 mm, otherwise the shoulders may interfere with the case. Always verify technical specifications before purchase.

What is the average lifespan of a leather strap for the Nomos Orion 326?

A quality leather strap lasts between 3–5 years with daily use, depending on exposure to moisture and perspiration. Shell cordovan, being more resilient, can reach 7–10 years. FKM rubber has a similar lifespan to leather, but with less aesthetic wear. Regular maintenance (cleaning and drying) extends service life.
