The lug width of the A. Lange & Söhne Saxonia 215.026 is precisely 19 millimetres. This measurement represents the internal distance between the case lugs and is essential for selecting a compatible strap. To verify it correctly, use a digital calliper positioned perpendicularly to the case plane, measuring the internal space between the two lugs.

For the Saxonia 215.026, we recommend alligator leather in vegetable tanning as the primary choice: the natural texture dialogues beautifully with the watch's formal purity and develops a fascinating patina over time. Alternatively, Swiss calf leather in tannin tanning or shell cordovan offer refined solutions. Strap thickness should not exceed 2 millimetres at the lug area to maintain the precise proportions designed by A. Lange & Söhne.

The strap is changed using a spring bar tool or a small flat screwdriver. Position the watch on a soft cloth, locate the small spring housed vertically beneath each lug of the case, and gently release the spring's tension by pushing the tool downward. Extract the old spring bar and insert the new one from your new strap, ensuring it is firmly seated in both holes. This operation requires care to avoid scratching the white gold case.

Yes, any strap equipped with 19-millimetre spring bars is compatible with the 215.026. However, we recommend straps crafted by specialised ateliers that understand the precise tolerances required. An aftermarket strap must be made from high-quality materials (alligator, cordovan, vegetable-tanned calf) and should not diverge from the watch's aesthetic philosophy: sobriety, formal coherence, and natural patina development.

The lifespan of a leather strap depends on frequency of use, climate conditions, and leather quality. High-quality alligator or shell cordovan, with proper maintenance, can last 3–5 years of daily wear. Vegetable-tanned calf tends to develop creasing in the inner fold after 2–3 years. Determining factors: avoid prolonged moisture exposure, occasionally apply natural leather balm, and alternate with other straps to distribute stress. A well-maintained strap can continue to provide service beyond this period, with increased visibility of patina.
