The Lange 1 110.041, seen from the bench

The Lange 1 was introduced in 1994 as the first watch of the renaissance of A. Lange & Söhne after German reunification. It features the in-house manufactured manual-winding caliber L901.4 with power reserve indicator, small seconds, and the characteristic asymmetric dial. 20mm lugs complete the case in precious metal.

Frequently asked questions

What is the lug width of the A. Lange & Söhne Lange 1 110.041?

The <a href="https://milanostraps.it/pages/termine-glossario/misura-ansa">lug width</a> of the A. Lange & Söhne Lange 1 110.041 is 20 millimetres. This dimension is standard across all variants of the model, regardless of case material or production year. Always verify the lug width before purchasing a replacement strap, as even 1 mm deviations will prevent proper fit within the case lugs.

What is the best strap material for the Lange 1 110.041?

For the Lange 1 110.041 in white gold, the most appropriate materials are: genuine <a href="https://milanostraps.it/pages/termine-glossario/alligatore">alligator</a> (fine grain, neutral colours such as black or dark brown to enhance the white gold), <a href="https://milanostraps.it/pages/termine-glossario/shell-cordovan">shell cordovan</a> of quality (develops an admirable patina over time), and aniline calf leather (softness and natural wax absorption). Rubber and fabric straps are discouraged: they do not reflect the inherent elegance of the timepiece.

How do you change the strap on an A. Lange & Söhne Lange 1?

The strap is changed by removing the spring bars that connect the case lugs to the original strap. Obtain a dedicated spring bar tool or consult a professional watchmaker. Never force the spring bars with improvised tools: the risk of scratching the gold case lugs is significant. The procedure takes minutes, but professional expertise is advisable for watches in this category.

Does an aftermarket strap compatible with the 110.041 maintain the watch's value?

Yes, provided the strap is of excellent quality and branded. An artisanal strap in <a href="https://milanostraps.it/pages/termine-glossario/concia-vegetale">vegetable tanning</a> or genuine alligator adds perceived value; conversely, mediocre straps may diminish overall aesthetic impact. For the Lange 1 110.041, a bespoke strap tailored to measure represents a choice that enhances the case's value without compromise.

How long does a leather strap last on an A. Lange & Söhne Lange 1?

Lifespan depends on material and usage. A quality alligator strap lasts 5–8 years with daily wear and regular maintenance (cleaning with a damp cloth, treatment with specific creams every 12 months). Shell cordovan, due to its fibrous structure, can last 8–10 years. Aniline calf, more delicate, requires greater attention but retains softness longer. All age naturally: patina is not decay but testimony to mindful ownership.
