The lug width of the A. Lange & Söhne 1815 236.049 is 20 mm. This is the standard measurement to use when selecting any replacement strap compatible with this reference.

What is the best strap for the A. Lange & Söhne 1815 236.049 in platinum?

For the 1815 236.049 in platinum, we recommend a smooth alligator strap with a polished or satin finish, in black, havana brown, or anthracite grey. Alligator is the material that best respects the formal rigor of the dial and complements the restraint of platinum without overwhelming the original design.

How do you change the strap on the A. Lange & Söhne 1815 236.049?

The strap on the 1815 236.049 is replaced using a dedicated springbar tool to remove the spring bars that secure the strap to the lugs. The operation requires care to avoid scratching the platinum case: use of a tool with a plastic or nylon tip is recommended, or alternatively, entrust the work to a qualified watchmaker.

How long does a leather strap last on an A. Lange & Söhne 1815?

The lifespan of a leather strap depends on the quality of the leather, frequency of use, and usage conditions. A high-quality alligator or calf strap, with regular use and proper care (kept away from water and excessive perspiration), has an average life of 2-4 years while maintaining a presentable appearance. Artisanal straps made from selected leathers tend to last longer and develop distinctive character over time.
