Strap for Kleine Lange 1 Soirée White Gold

The lug width of the A. Lange & Söhne Lange 1 813.044 is 19 millimetres. This dimension is precise and features no tolerance variations: it represents the internal space between the spring bars that connect the case to the straps. Always verify with a digital calliper before ordering a compatible strap to eliminate any uncertainty.

Nile alligator leather with vegetable tanning represents the natural pairing for the 813.044, owing to its evolving patina and structured grain that dialogue with the 900‰ white gold case. Shell cordovan offers a sophisticated alternative with superior resistance to wear. Avoid synthetic materials and NATO fabrics: the 813.044 does not tolerate aesthetic compromise.

Strap replacement requires the use of a spring bar remover tool. Position the watch with the case facing downwards, insert the tool tip into the space between the spring bar and the lug, applying gentle pressure to compress the internal spring. Once the spring bar is released, remove the old strap and insert the new one. We recommend having this operation performed by a specialist retailer to avoid damaging the case.

Yes, any strap with a certified 19 mm lug width is compatible with the 813.044, provided the construction respects elevated quality standards. Compatibility is guaranteed by lug width geometry; however, we recommend choosing noble leathers (alligator, shell cordovan, quality calf) and precious metal clasps to maintain the aesthetic and material coherence of the watch.

Strap longevity depends on the leather used and the intensity of daily wear. Alligator and shell cordovan, if properly maintained, last 4–6 years under daily wear conditions. Calf leather, owing to its less dense structure, wears more rapidly (2–3 years). Avoid prolonged exposure to humidity, direct sunlight and heat sources. Casati Milano provides an 18-month warranty against manufacturing defects.
