Strap for Datograph Perpetual White Gold / Grey

The lug width of the A. Lange & Söhne Saxonia 410.038 is 20 mm. This measurement, determined by the inner distance between the two lugs of the case, is standard for this model and is compatible with all straps and bracelets certified for 20 mm lug width. The measurement must be taken from the inner point of one lug to the inner point of the other lug, not across the external circumference of the case.

For the A. Lange & Söhne Saxonia 410.038 in white gold, the most coherent strap is alligator leather dyed in dark brown (beaver, cognac) with matte finish and natural grain. Alternatively, smoked calf leather with vegetable tanning offers a patina that ennobles the strap over time. For casual or summer contexts, ivory calf leather creates monochromatic harmony with the gold case. Shell cordovan is not recommended, as its intrinsic lustre may compete with the metal's patina.

Changing the strap on the A. Lange & Söhne Saxonia 410.038 requires removing the fixing pins (spring bars) located laterally within each lug. Use a proper spring bar tool to compress the internal spring and extract the pin. Once the old strap is freed, align the new strap's holes with the lugs and press the pin until it clicks into place. We recommend having this procedure performed by a qualified watchmaker if you are not experienced with the operation.

A high-quality artisanal leather strap for the A. Lange & Söhne Saxonia 410.038, with vegetable tanning and professional finishing, has an average lifespan of 3-5 years with moderate daily use. Longevity depends on the wear of the spring bar, leather quality, frequency of use, and periodic maintenance. MilanoStraps guarantees 18 months against manufacturing defects for custom straps made by Casati Milano. To extend lifespan, we recommend alternating the strap every 2-3 days and keeping it dry, avoiding immersion in salt or chlorinated water.
