Strap for Ludwig 33 Anthrazit

The Nomos Glashütte Ludwig 245 features a lug width of 17.00 mm. This dimension is precise and consistent across all production units. When measuring with a digital calliper, ensure you measure the internal distance between the two lugs, excluding the thickness of the lugs themselves.

An alligator strap with fine grain is the ultimate luxury choice, whilst vegetable-tanned calf leather offers durability and natural ageing. For a sober sporty approach, a cotton/linen NATO remains appropriate. FKM rubber in dark grey ensures versatile use without compromising the minimalist elegance of the model.

Use a spring bar tool or small screwdriver to push the lug pin from one side to the other. Proceed slowly to avoid scratching the case. Once the pin is removed, the old strap comes away. Insert the new strap (17 mm), align it with the lug holes, reinsert the pin and secure under slight tension.

Yes, provided the strap has an exact lug width of 17 mm and thickness consistent with the case proportions (typically 3.5–4.5 mm). A strap from a reputable manufacturer, crafted in quality leather or rubber, maintains the aesthetic proportion of the model and ensures complete mechanical compatibility.

A high-quality alligator or vegetable-tanned calf strap, with proper maintenance (avoiding prolonged water exposure, keeping dry), typically lasts 3–5 years before visible wear develops. Patina develops after 6–12 months, adding character. An FKM rubber strap generally lasts 4–7 years, depending on sun exposure and skin pH.
