Strap for Lange 31 White Gold / Grey

The lug width of the Saxonia 130.039 is 22mm. This technical specification is essential when purchasing an aftermarket strap: ensure the strap you select is exactly 22mm wide to guarantee proper fit in the lugs and maximum stability. A undersized strap (20mm) will be unstable; an oversized strap (24mm) will not physically fit into the case lugs.

For the Saxonia in white gold, alligator leather is the most aesthetically congruent choice: its regular texture and uniform grain emphasise the German design's minimalism. Vegetable-tanned calf leather is equally excellent for those who appreciate a patina that develops gracefully over time. Shell cordovan offers structural durability and a prestigious natural sheen. For informal contexts, a NATO strap in fine weave fabric or FKM rubber guarantees practicality without compromising quality.

Changing the strap on the Saxonia 130.039 requires a spring bar tool. Place the watch on a stable surface, locate the horizontal metal pin inside the upper lug, insert the tool's tip into the small hole on the pin to compress the internal spring, then remove the pin. Repeat for the lower pin. Proceed identically with the new strap, ensuring the pin is fully inserted and locked. If you lack experience, consult a qualified watchmaker or Casati Milano for professional strap change service.

Any strap with a 22mm lug width is compatible with the Saxonia 130.039. Compatible options include alligator, calf, shell cordovan, NATO, and FKM rubber, provided the width is precisely 22mm. Verify lug width specifications in product descriptions. Milanostraps.it offers a curated collection of 22mm-compatible straps selected for construction quality and visual harmony with the white gold case.

Strap longevity depends on material, frequency of use, and climate conditions. A quality alligator or calf strap, with moderate daily use, typically lasts 4–6 years before leather loses elasticity and shows signs of wear. Shell cordovan, owing to its dense fibrous structure, can reach 7–8 years. A NATO fabric strap offers similar duration but resists moisture better. Milanostraps.it provides an 18-month warranty against manufacturing defects. Regular maintenance – drying after humidity exposure, occasional application of leather conditioner – significantly extends strap lifespan.
