Strap for Saxonia White Gold / Diamond

The lug width of the A. Lange & Söhne Saxonia 878.029 is 18mm. This dimension is the specific standard for the compact 35mm case format and must be scrupulously observed when replacing the strap, as even minor variations compromise the proportional balance calibrated by the manufacture.

For the 878.029 in white gold, we recommend alligator in polished black or tobacco brown, or calf leather with vegetable tanning in the same tones. Alligator offers natural texture and rich patina development over time; calf provides constructive softness and authentic ageing. Avoid pale-coloured straps or modern textiles (NATO, rubber) that conflict with the Saxonia's purist philosophy.

Use a spring bar tool to extract the anchor pins (spring bars) from the case lugs. Position the tool in the lateral groove of the pin, gently lift and the strap will detach. Insert the new strap, aligning it correctly before repositioning the pin. If inexperienced, consult a certified watchmaker to avoid scratching the case.

Yes, any strap with 18mm lug width is mechanically compatible. However, aesthetic and constructive compatibility varies significantly. We recommend high-quality leathers (alligator, calf, shell cordovan) from specialised artisans. Avoid industrial straps that compromise the constructive dignity of the watch.

A high-quality leather strap (alligator, vegetable-tanned calf) typically lasts 3–5 years with daily wear, subject to natural wear from perspiration, moisture and flexing. Longevity depends on care: avoid prolonged water immersion, dry after rain and rotate straps to distribute wear. A natural patina developing over time is a sign of quality and authentic construction.
