Strap for Lange 1 Tourbillon Perpetual Calendar White Gold

The lug width of the A. Lange & Söhne Lange 1 720.038 is 22 mm. This measurement is taken internally between the two lugs at the strap attachment point, ideally using a vernier calliper for accurate results.

For the 720.038 reference in white gold with tourbillon and perpetual calendar, a vegetable-tanned alligator strap is the most appropriate choice, consistent with its haute horlogerie positioning. Shell cordovan is an excellent alternative, offering a slim profile and a natural lustre that complements the white gold case.

The strap on the Lange 1 720.038 is secured with standard 22 mm spring bars. A fine-tipped spring bar tool is sufficient to remove the bars from the lugs and fit a new strap. It is advisable to work on a soft surface to protect the white gold case from scratches.

Yes, any strap with a 22 mm attachment width is technically compatible with the A. Lange & Söhne Lange 1 720.038, provided the spring bars are of the correct diameter. Milanostraps.it offers a range of handcrafted 22 mm straps made to measure and compatible with the original lugs of this reference.

The longevity of a leather strap depends on the material, frequency of wear and level of care. A quality vegetable-tanned alligator strap, maintained regularly with a suitable leather conditioner, typically lasts between two and four years of daily use. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
