Strap for Metro Neomatik 39 Nachtblau

The lug width of the Nomos Glashütte Metro 1115 is 19 mm. This dimension is measured from the internal base of one lug to the other, perpendicular to the watch's horological axis. It is a European ergonomic standard that reflects the case diameter (38.50 mm) and ensures balanced proportions on most wrists. Before purchasing an aftermarket strap, always verify this measurement with a digital calliper to ensure perfect compatibility.

The best strap for the Metro 1115 depends on usage context and aesthetic preferences. Alligator with vegetable tanning in cognac tone is the classical choice: its characteristic grain dialogues elegantly with the white lattice dial, and vegetable tanning imparts a natural patina that ages with dignity. European calf in dark brown represents a versatile alternative with uniform texture. For formal corporate environments, black calf with stainless steel deployante offers maximum professionalism. For casual-sporting contexts, a cotton-silk NATO maintains the minimalist essence without compromise.

Changing the strap on the Metro 1115 requires a spring bar tool. Position the watch on a flat surface and insert the forked tip of the spring bar tool beneath the spring bar pin, applying gentle inward pressure. The pin will release, allowing you to remove the old strap. Repeat on the opposite lug. When installing the new strap, ensure the spring bar pin is fully inserted and locked by the spring mechanism. If uncertain, entrust the task to a professional: Casati Milano offers personalised strap-change service with sartorial consultation.

Yes, numerous aftermarket straps are compatible with the Metro 1115, provided the lug width is precisely 19 mm. Italian artisanal specialists such as milanostraps.it offer a curated selection of alligator, calf, NATO and natural vulcanised rubber, all available in 19 mm width. Artisanal quality ensures millimetric compatibility and superior longevity. Before purchase, always verify that the vendor specifies the lug width (19 mm) and that materials are documented in terms of tanning method, origin and thickness.

The longevity of a leather strap depends on material, tanning method and maintenance. Artisanal-quality alligator with vegetable tanning guarantees 5–7 years of service with daily wear and regular maintenance (weekly cleaning, drying after moisture exposure). Standard European calf typically lasts 3–5 years. Maintenance consists of weekly cleaning with a soft, dry cloth and quarterly application of natural leather balm. If frequently exposed to high humidity, tropical climates or excessive perspiration, durability decreases proportionally. To extend strap life, rotate with alternative models and store in a dry environment away from direct heat sources.
