Nomos Glashütte
Metro 1113.S1— lug 19mm

The lug width of the Nomos Glashütte Metro 1113.S1 is 19mm. This measurement is calculated from the inner edge of the left lug to the inner edge of the right lug, excluding the case diameter itself. When purchasing a replacement strap, you must ensure it has a 19mm width lug to fit the watch correctly.

The ideal strap depends on intended usage. For formal occasions, we recommend vegetable-tanned alligator in medium brown or cognac tones, which emphasises the minimalist elegance of the case. For daily office wear, vegetable-tanned calf leather or Italian shell cordovan offer supple handling and superior durability. For sportive-casual styling, NATO or FKM rubber straps maintain Bauhaus purity without compromise.

Strap replacement requires a dedicated spring bar removal tool. Position the watch on a stable surface, locate the small holes in the lugs, insert the flat end of the spring bar tool into the hole, and apply gentle inward pressure to release the pin. Remove the old strap, align the new strap lug with the watch lugs, and allow the spring bar to return to position with an audible click.

Yes, any strap with a 19mm lug width is compatible with the 1113.S1, regardless of brand. However, we recommend straps of certified quality craftsmanship (vegetable leather, double stitching) to preserve the aesthetic value of the timepiece. Generic or poorly-made straps undermine the refinement of the Nomos case.

Leather strap longevity depends on usage and tanning method. A high-quality artisanal vegetable-tanned strap, worn daily, typically lasts 18–36 months before showing evident wear (thinning, cracking, buckle failure). Exposure to perspiration, moisture, and UV rays accelerates deterioration. Regular maintenance (cleaning, conditioning) and rotating multiple straps significantly extend functional lifespan.
