A. Lange & Söhne
Lange 1 101.032— lug 20mm

The A. Lange & Söhne Lange 1 reference 101.032 is fitted with a 20 mm lug width. This measurement is standard across the entire 38.5 mm Lange 1 family and should be verified between the two lugs using a caliper before purchasing any compatible strap.

For the Lange 1 101.032 in rose gold, a semi-polished Louisiana alligator strap in burgundy, marron glacé, or cognac tones aligns best with the watch's manufacturing heritage. The scale texture visually complements the hand-finished details of the L901.0 caliber. Smooth box-calf leather offers a more understated alternative, developing a richer patina over time. Casati Milano creates both options bespoke with 20 mm lugs.

The Lange 1 101.032 strap is replaced using a springbar tool or lever-style screwdriver, gently prying between the lug and strap to compress the 20 mm spring bars. It is recommended to work on a soft surface to protect the rose gold case from scratches, or to entrust the task to a watchmaker or the Casati Milano service during strap fitting at their atelier.

Yes. The Lange 1 101.032 uses a standard 20 mm springbar, compatible with any aftermarket strap measuring 20 mm at the lugs. Milanostraps.it offers a selection of artisanal 20 mm straps in alligator, calf leather, NATO, and rubber. Casati Milano also produces bespoke straps by appointment, custom-fitted to the client's watch.

A leather strap's lifespan depends on the quality of tanning and daily use. A strap in quality alligator or calf leather with nappa lining and waxed stitching typically lasts between 2 and 4 years with regular wear. Casati Milano straps are covered by an 18-month warranty against manufacturing defects. Rotating between two straps and storing the watch away from humidity significantly extends leather life.
