Strap for 1815 Yellow Gold

The lug width of the A. Lange & Söhne 1815 206.021 is precisely 19 millimetres. This measurement is critical for selecting the correct strap: the strap must have a width of 19mm to fit properly into the watch lugs without forcing or excessive play.

The ideal strap for the 206.021 is crafted from alligator leather, whose sophisticated and irregular texture pairs perfectly with the warm tone of the yellow gold case. Alternatively, calf leather finished with vegetable tanning offers a patina that naturally evolves over time, developing a fascinating colour stratification. For colour pairings, dark brown, cognac, black, or burgundy are the most versatile and refined choices.

Strap replacement involves removing the existing strap from the watch lugs using an appropriate tool (a strap removal tool or small flat screwdriver) to push the metal pin securing the strap. Once one end is freed, extract the strap from both lugs. To install the new strap, reverse the process: insert the pin into the first lug, then slide the strap under both lugs until the second pin is positioned in the opposite lug. If unfamiliar with this procedure, consult a jeweller or specialised watchmaker.

Absolutely. A quality artisanal aftermarket strap is not only compatible but often represents the most intelligent choice. The key is selecting a strap crafted from noble materials (alligator, vegetable-tanned calf) and made by specialists who understand the proportions and character of the watch. A bespoke 19mm artisanal strap with refined finishing further enhances the aesthetic value and daily practicality of your A. Lange & Söhne.

The lifespan of a leather strap depends on intensity of use, climatic conditions, and material quality. A strap in superior alligator or calf leather, vegetable-tanned, typically lasts 4–6 years with daily wear. With occasional use, durability extends further. The patina developing over time is part of natural leather's beauty and represents aesthetic enrichment. With proper maintenance (periodic cleaning, avoiding stagnant water), the strap remains in good condition for many years. Artisanal Casati Milano straps include an 18-month warranty against manufacturing defects.
