What I'm asked about the Junghans Max Bill 027/4700.00
What strap size does the Junghans Max Bill 027/4700.00 take?
The Junghans Max Bill 027/4700.00 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.
Can the strap on the Junghans Max Bill 027/4700.00 be changed?
Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Yes, in 20 mm leather. On a 38 mm case a calf strap works every day; if you want something more, alligator.

A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions
What is the best strap for the Junghans Max Bill 027/4700.00?
For the Max Bill 027/4700.00, we recommend natural alligator with vegetable tanning (cognac or black) for uncompromising elegance, or vegetable-tanned calf that ages beautifully. For versatility, a cordura NATO is practical and reversible. For sport use, satinised FKM rubber maintains stylistic coherence whilst preserving functionality.
Can I use aftermarket compatible straps on my Max Bill 027/4700.00?
Yes, provided they respect the 20-millimetre lug width specification. Artisanal quality straps are not only compatible, but often enhance the aesthetic experience compared to original straps. Always verify the technical specifications of the product before purchase.
How long does a leather strap last on the Junghans Max Bill 027/4700.00?
A quality leather strap (alligator or vegetable-tanned calf) lasts 3–5 years under normal wear with regular maintenance. Exposure to humidity, direct heat and chemical contaminants reduce longevity. Avoid wetting the strap during swimming or bathing. Vegetable-tanned leather can be regenerated with periodic applications of shea butter.
