FAQ

What is the lug width of the Junghans Max Bill 027/4002.44?

The Junghans Max Bill 027/4002.44 has a lug width of 20 millimetres. This measurement is the distance between the two spring bars that hold the strap. Using a strap specifically designed for 20mm ensures optimal compatibility and eliminates unnecessary stress on the case.

Which strap would you recommend for the Max Bill 027/4002.44?

For the Max Bill 027/4002.44, we recommend straps in vegetable-tanned leather, alligator, or alternatives such as NATO and brushed rubber. The choice depends on your aesthetic: a brown alligator strap enhances the watch's minimalist design, whilst a NATO offers versatility and practicality. Crucially, the strap must respect the rational proportions of the Bauhaus design philosophy.

How do you change a strap on a 20mm lug width watch?

To change the strap, you will need a spring bar tool or a small screwdriver. Insert the tool into the lateral hole of the spring bar to compress its internal spring, then slide the old strap outward. Repeat on the opposite side. Insert the new strap by aligning the holes with the pins and release. Perform this operation carefully to avoid scratching the case.

Can I use an aftermarket strap on a Junghans Max Bill?

Yes, aftermarket straps compatible with the 20mm lug width can be used. However, verify that the strap has correct visual proportions and that the lugs (the small leather pieces that wrap around the pins) do not interfere with the crystal. A quality artisanal strap ensures durability and aesthetic coherence with the excellence of the watch.

How long does a natural leather strap last on a watch like the Max Bill?

A vegetable-tanned leather strap, if worn daily, typically lasts 3 to 5 years. Longevity depends on humidity, perspiration, and maintenance: conditioning the leather periodically significantly extends its lifespan. Alligator and shell cordovan are more resistant and can last 7 to 10 years with proper care. The patina that develops is part of the strap's beauty and history.
