Strap for Nav B-Uhr 47 Handwinding

The lug width of the Steinhart Pilot F0318 is precisely 22mm. This measurement determines mechanical compatibility with any aftermarket strap. To verify, measure the space between the terminal lug of the case and the starting point of the original strap: it must be exactly 22mm.

For the Pilot F0318, we recommend robust straps that respect the martial aesthetic of the watch: leather with vegetable tanning in neutral tones (brown, grey), NATO in regenerated cotton, or technical rubber. We advise against ornamental or polished straps; the F0318 demands austerity and functional design.

The strap is secured to the case via spring bars. Use a dedicated spring bar tool: apply light pressure on both sides of the bar until it protrudes slightly, then extract it. For fitting, insert the bar into its seat and press until you hear the click. If inexperienced, consult a local watchmaker to avoid scratches on the case.

Yes, the F0318 is fully compatible with any strap featuring a 22mm lug width. Compatibility is determined exclusively by this parameter. You may replace the original strap with leather, NATO, rubber, or any other material, provided the lug width is exactly 22mm.

A high-quality leather strap with vegetable tanning has an average durability of 4–6 years with daily wear, depending on climate, frequency of use, and maintenance. A synthetic or rubber strap lasts 5–10 years. Natural leather develops a noble patina over time; rubber resists moisture better but loses elasticity. We recommend rotating between multiple straps to extend their lifespan.
