It depends on the use: for formal contexts we recommend black or brown alligator in vegetable tanning for personalized patina. For everyday versatility, soft calf leather in tan tones. For casual wear, navy blue or green NATO. What matters is that it is compatible with the 22 mm lug width.

You will need specific tools: a spring bar tool and a flat, well-lit work surface. Insert the tip of the tool under the spring, press gently downward to release the end, extract the metal pin, then replace the strap by aligning the pins with the lugs.

A quality leather strap (alligator, calf, cordovan) typically lasts 3–5 years with regular use and periodic care. Exposure to sweat, water, and UV accelerates wear. Applying UV protection and allowing complete drying after moisture contact extends its life. NATO or rubber straps last longer in humid environments.
