FAQ
What is the lug width of the Nomos Glashütte Orion 397?
The lug width of the Nomos Glashütte Orion 397 is 18 mm. This measurement should be verified by placing a ruler between the inner edges of the lugs. A tolerance of ±0.1 mm is acceptable for artisanal straps of quality.
Which strap do you recommend for the Nomos Glashütte Orion 397?
For the 397 we recommend alligator crocodile with uniform grain and matte finishes, or vegetable-tanned calf leather that ages beautifully. For a sporty approach, NATO straps in artisanal fabrics (dark blue, burgundy) maintain Bauhaus austerity. Pressed FKM rubber represents the pure functional choice.
How do I change the strap on my Nomos Glashütte Orion 397?
To change the strap, remove the lug pin (spring bar) using a specific spring bar remover tool. Position yourself over a soft cloth to prevent drops, compress the inner pin and slide out the old strap. Insert the new strap and ensure the pin is fully seated on both sides.
Can I use an aftermarket strap for the Nomos Glashütte Orion 397?
Yes, provided the strap is dimensioned with 18 mm lugs. Artisanal Casati Milano straps from Milano Straps are specifically crafted for this measurement, guaranteeing perfect fit and correct visual proportions with the 36.40 mm case.
How long does a leather strap last on the Nomos Glashütte Orion 397?
A quality leather strap (alligator, vegetable-tanned calf) lasts 3-5 years with regular daily wear and proper maintenance. Longevity depends on sun exposure, humidity and frequency of wear. Natural leather develops patina over time, improving aesthetically whilst wearing structurally.
