Strap for Orion 38 / Closed Case Back

The Nomos Glashütte Orion 387 features a lug width of 19 millimetres. This specific measurement requires straps built to this exact dimension, as even minor variations can cause excessive play or unwanted structural tension on the case.

To enhance the architectural proportions of the 387, we recommend a shell cordovan strap in cognac with vegetable tanning, or sharp-grain alligator in dark brown. Both create formal-informal harmony without competing with the milky quadrant. As a minimalist alternative, vegetable-tanned calf in cream preserves the Glashütte austerity.

The 387's strap is replaced via the lateral lugs: use a spring bar tool to remove the elastic pin securing the old strap to the case shoulders. Insert the new 19mm strap on both lugs, ensuring perfect fit in the housing. Avoid forcing, which could scratch the satin stainless steel.

Yes, provided it is constructed specifically for a 19 millimetre lug width. Artisanal bespoke straps guarantee precise millimetre tolerances and sartorial-grade materials. Always verify technical specifications before purchase, excluding tolerances of ±0.5mm that would compromise fit.

A vegetable-tanned leather strap of quality, worn daily, maintains structural integrity for 3–5 years before visible wear emerges. Longevity depends on humidity, frequency of use, and maintenance: monthly dusting and occasional cleaning with a damp cloth preserve patina and flexibility. Shell cordovan, being denser, typically lasts longer than calf.
