Strap for Orion 35 Rose / Open Case Back

The lug width of the Nomos Glashütte Orion 352 is 18mm. This measurement represents the distance between the two spring bar attachments on the case where the strap inserts. It is a distinctive size that underscores the harmonic proportions of this 35mm diameter timepiece.

For the Orion 352, we recommend fine-grain alligator with subtle patina, or vegetable-tanned calf leather if you desire natural ageing. A minimalist cotton-polyamide NATO is ideal for casual contexts. The choice depends on usage: formal settings call for alligator or calf, while casual wear accommodates NATO or textured rubber.

Strap change is performed via the spring bars integrated into the case. Using a spring bar tool, gently lift the existing strap from the lugs, then insert the new 18mm strap into the same lugs. The operation requires precision to avoid scratching the case. Professional assistance from a watchmaker is optional but recommended for those seeking maximum care.

Yes, absolutely. The Orion 352 accepts any 18mm strap of equivalent build quality. We recommend certified alligator, vegetable-tanned calf, shell cordovan, or NATO options. The critical point is ensuring the lugs fit perfectly without lateral play and that the strap is proportioned to the slender 35mm case.

A quality calf leather strap typically lasts 5-7 years with moderate daily wear. Alligator and shell cordovan can extend lifespan to 10+ years thanks to leather density. Vegetable tanning promotes ageing, creating patina rather than deterioration. Regular maintenance—cleaning and air circulation—significantly extends strap longevity.
