Strap for Nav B-Uhr 47 ST1 Premium Anthracite

The lug width of the Steinhart Pilot P0910 is exactly 22 millimetres. This measurement is taken from the base of the upper lug to the base of the lower lug on the case. Any aftermarket strap must conform precisely to this dimension to ensure proper fit without play or binding.

For the Steinhart Pilot P0910, we recommend either a vegetable-tanned leather strap in Tobacco tone or a black alligator strap for optimal aesthetic and functional balance. Alligator offers superior durability and a natural grain that echoes the original fliegeruhren of the 1940s–50s, whilst Tuscan leather develops a natural patina over time. For tactical or extreme outdoor use, a dense nylon NATO strap represents the most versatile and resilient option.

You will need a spring bar removal tool or a small flathead screwdriver. Invert the watch and locate the spring bar running through the upper and lower lugs. Gently compress and remove the spring bar along one of the lugs (typically positioned at a slight angle), withdraw the old strap, align the new strap with the lug holes, and reinsert the spring bar until it seats fully. Verify that both lugs are secure before wearing the watch.

Yes, any strap with a 22mm lug width is fully compatible with the Steinhart Pilot P0910. Milano Straps offers an extensive selection of artisanal straps in various finishes and materials—from alligator to shell cordovan, vegetable-tanned leather, NATO, and rubber—all available in 22mm and tested for proper fit on Steinhart lugs.

Strap longevity depends on material and usage conditions. A vegetable-tanned alligator strap of artisanal quality, under moderate daily wear, lasts 15 to 25 years. A vegetable-tanned calf strap typically endures 10 to 15 years before showing fatigue. Nylon NATO straps retain their structural properties for over 30 years if not subjected to excessive tension. To maximise lifespan, clean regularly with a soft dry cloth and protect from prolonged perspiration and repeated immersion unless specifically treated.
