Strap for Datograph Perpetual White Gold / Grey / Bracelet

The lug width of the A. Lange & Söhne Saxonia 410.430 is 20mm. This measurement is taken with a digital calliper positioned between the two lugs at the level of the springbar tube, and is the decisive factor when selecting a compatible aftermarket strap.

For a perpetual calendar in white gold such as the Saxonia 410.430, a vegetable-tanned alligator strap is the most coherent choice: the natural grain complements the complexity of the dial and the L952.1 calibre. Shell cordovan develops a distinguished patina over time, whilst black boxcalf leather remains the most versatile option for daily wear.

The strap on the Saxonia 410.430 is secured by standard 20mm springbars. To replace it, insert a fine-tipped springbar tool into the lug hole to release the spring bar. It is advisable to work on a soft surface to avoid scratching the white gold case, and to verify that the springbar dimensions are compatible with the lug thickness.

Yes, any strap with a 20mm attachment and standard springbars is technically compatible with the Saxonia 410.430. Milanostraps.it offers a selection of handcrafted straps in alligator, calfskin, shell cordovan and rubber, specifically matched to this reference, with stitching and finishing options customisable through the Casati Milano bespoke service.

The lifespan of a leather strap depends on leather quality, tanning method and frequency of use. A high-grade vegetable-tanned alligator strap typically lasts 3 to 5 years with regular wear. Shell cordovan tends to last longer due to the dense structure of the equine shell leather, whilst calfskin straps have an average lifespan of 2 to 3 years. The Casati Milano guarantee covers manufacturing defects for 18 months.
