Strap for Classic Field Sabot Foundation

The Bausele Field Watch B31SBN3WH1 features a lug width of 22 millimetres. This measurement refers to the distance between the two lugs (the attachment points on the case) and is the essential parameter for selecting a compatible strap. To verify the lug width of your watch, use a digital calliper, positioning it perpendicular to the case length between the two lugs.

For the B31SBN3WH1, a vegetable-tanned leather strap represents the sartorial choice of excellence, as the patina developed over time emphasises the tool-watch character of the model. However, a NATO strap in high-quality nylon maintains the military heritage of the field watch, whilst an alligator strap offers a distinctive grain pattern and humidity resistance. The choice depends on your usage: elegant daily wear (leather), tactical versatility (NATO), humid environments (alligator).

To change the strap on a watch with fixed lugs, follow these steps: 1) Obtain a spring bar tool (a specialised strap changing tool). 2) Rest the watch on a soft surface. 3) Insert the flat tip of the tool under the spring bar to compress it and create space. 4) Extract the pin from its seat. 5) Remove the old strap. 6) Insert the pin into the new strap, ensuring it is positioned correctly. 7) Gently insert it into the opposite lug whilst maintaining spring bar compression. 8) Verify that it is securely fastened. If you feel uncertain, consult a professional watchmaker.

Yes, any strap with a lug width of 22 millimetres is fully compatible with the B31SBN3WH1. Artisanal leather straps, NATO straps, rubber straps and metal straps with this specific measurement will fit perfectly onto the case lugs. Always verify that the strap is indeed 22 millimetres before purchase.

The lifespan of a leather strap depends on intensity of use and environmental conditions. A high-quality vegetable-tanned leather strap, worn daily in moderate conditions, has an average useful life of 3 to 5 years. Frequent exposure to humidity, perspiration or direct UV rays reduces this duration. To extend your strap's lifespan, perform periodic maintenance with bespoke natural leather conditioners, remove the watch during heavy rain exposure, and rotate between different straps to distribute wear over time.
