A. Lange & Söhne
Lange 1 101.027— lug 20mm

The lug width of the A. Lange & Söhne Lange 1 reference 101.027 is 20mm. This dimension is measured with a digital caliper positioned inside the two case lugs, at the spring bar attachment point. All 20mm straps in the milanostraps.it catalog are compatible with this model.

For the Lange 1 101.027 in white gold, the most suitable strap is alligator leather with a matte or semi-matte finish, preferably in midnight blue, anthracite grey, or black. The regular grain of crocodile leather complements the polished surface of white gold without competing with the complexity of the dial. Avoid warm tones such as cognac or havana brown, which contrast with the rationalist Saxon aesthetic of this timepiece.

The strap on the Lange 1 101.027 is replaced using a T-shaped or thin flat-tip spring bar tool, applying leverage to the spring bar inside the lug. The operation does not require authorized technical service. It is recommended to use a protective pad to avoid scratching the white gold case during the procedure. Standard 1.5mm diameter spring bars are compatible with most 20mm aftermarket straps.

Yes. The Lange 1 101.027 has a standard 20mm lug width with conventional spring bars, perfectly compatible with quality aftermarket straps. milanostraps.it offers a selection of handcrafted 20mm straps in alligator, calf, and other materials, made with buckles and loops sized to ensure proper fit and proportions relative to the 38.50mm case.

The lifespan of a leather strap depends on material quality, frequency of use, and exposure to sweat and humidity. A high-quality alligator strap, with leather lining and hand-stitching, has an average lifespan of 2-4 years with regular use. Casati Milano straps are covered by an 18-month warranty against manufacturing defects. To maximize durability, avoid direct contact with water and rotate between multiple straps.
