How do I change the strap on the Milus LAB 01 MIL.01.001?

The strap of the Milus LAB 01 is changed by inserting a small tool (spring bar tool) into the spaces between the case and the lugs, compressing the elastic pins that hold the strap in position.

Can I use an aftermarket strap on this model?

Yes, the Milus LAB 01 accepts any strap with a 20mm lug width. High-quality artisanal straps built to specification guarantee superior finishing, carefully selected leather, and properly shaped deployante clasps. Always verify specifications before purchase.

What is the lifespan of a leather strap for the Milus LAB 01?

A quality leather strap, whether vegetable-tanned or shell cordovan, typically lasts 3–5 years with moderate daily use. Longevity depends on sun exposure, humidity, frequency of wear, and maintenance. Regular care (gentle cleaning, annual conditioning) significantly extends the strap's life.
