Strap for Classic Field Onyx Black

The Bausele Field Watch B31SBN1BL1 features a lug width of 22mm. This dimension represents the physical width of compatible watch straps that fit into the case lugs. Measurement is taken between the pins using callipers, ensuring any quality aftermarket strap fits perfectly without play or excessive tension.

The choice depends on intended daily use. For tactical use and moisture resistance, a premium NATO or vulcanised rubber remains unbeatable. For professional elegance, a calf leather with vegetable tanning or alligator leather ensures natural patina development over time. MilanoStraps offers 22mm straps in all these materials, selected for construction quality and certified compatibility with the B31SBN1BL1.

The Bausele Field Watch uses standard fixed spring bar lugs. A spring bar tool (universal, inexpensive) is sufficient: insert the tool into the central hole, apply controlled pressure until the old spring bar detaches, remove the old strap, align the new strap with the lugs, and reinsert the spring bar. The operation takes less than three minutes and requires no technical skill.

Yes, provided they are specifically marked 22mm. MilanoStraps 22mm straps are tested and guaranteed compatible: standard width, fixed spring bar system, and mechanical precision are certified. Aftermarket compatibility represents a key advantage of Field Watches: total freedom of aesthetic personalisation without functional compromise.

Longevity depends on material and use frequency. A vegetable-tanned calf strap in daily use maintains structural integrity for 5-7 years, whilst aesthetic patina continuously improves. Alligator leather, thanks to superior construction density, can last 8-10 years. In humid environments (sea, rainy mountains), vulcanised rubber remains the most durable choice: virtually unlimited if kept clean. Mindful maintenance (drying after moisture exposure, seasonal conditioning) significantly prolongs the life of any natural material.
