Nomos Glashütte
Orion 393— lug 18mm

The lug width of the Nomos Glashütte Orion 393 is 18 millimetres. It is measured from the internal base of one attachment to the internal base of the opposite attachment, perpendicular to the case. This specific dimension requires bespoke, artisan-constructed straps to maintain balanced visual proportions.

Alligator leather of refined craftsmanship remains the choice of maximum elegance, as its natural texture dialogues seamlessly with the case's minimalism. Vegetable-tanned calf offers biological ageing over time. For a more versatile approach, textile NATO in hand-dyed weave ensures practicality whilst maintaining formal restraint. Shell cordovan represents a growing investment in natural patina development.

The strap is changed by extracting the spring bars that connect the strap to the case. Use a dedicated tool—a spring bar lever or dedicated tool—to gently compress the spring and slide the bar out. Insert the new strap, ensuring the spring bars are completely seated. The operation requires caution to avoid scratching the brushed stainless steel case.

Yes, any strap constructed for the 18-millimetre lug width is compatible with the Orion 393. The artisan straps from milanostraps.it are realised with this precise width, guaranteeing correct proportions and comfort without dimensional residue. It is essential to verify lug width before ordering.

A quality leather strap—alligator, shell cordovan, or vegetable-tanned calf—typically lasts 5–7 years with regular wear (4–5 days weekly). Ageing is not deterioration: it is natural patina development and chromatic change. The keeper loop tends to wear before the leather itself if subjected to repeated stress. Periodic maintenance with natural balms significantly extends strap lifespan.
