The Saxonia 308.031, seen from the bench

The Saxonia 308.031 embodies A. Lange & Söhne's philosophy through constructive depth and mathematical proportion rather than technological innovation. Equipped with the L921.4 manual caliber featuring a free anchor escapement, this 37 mm pink gold case pairs with 19 mm lugs and a sapphire display caseback revealing Perlage decoration and blued steel bridges. The central Big Date and small seconds reflect Glashütte craftsmanship tradition, with water resistance rated at 30 meters for daily use.

Frequently asked questions

What is the lug width of the A. Lange & Söhne Saxonia 308.031?

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the A. Lange & Söhne Saxonia 308.031 is 19 millimetres. This dimension is specific to the model and is essential to ensure compatibility with aftermarket artisanal straps.

What is the best strap for the Saxonia 308.031?

A strap in natural <a href="/pages/termine-glossario/alligatore">alligator</a> or <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> represents the optimal choice for the pink gold case. The texture of cordovan, with its natural satin grain, creates a chromatic dialogue with the case without competing visually. A sophisticated alternative is <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a>, which develops patina complementary to pink gold over time.

How do you change the strap on an A. Lange & Söhne Saxonia?

The strap is replaced via the case lugs. Using a dedicated tool (lug remover or small screwdriver), gently loosen the pins that hold the strap to the lugs. It is advisable to work on a soft surface and check pin alignment before final tightening. If you lack confidence, consult a certified watchmaker.

How long does a leather strap last on a watch like the Saxonia?

A high-quality artisanal leather strap typically lasts 5–7 years with moderate daily wear. Durability depends on tanning method, lug wear, ambient humidity and how much the strap is subjected to stress. Casati Milano straps benefit from an 18-month warranty against manufacturing defects. Natural leather, being a living material, ages by developing patina: this is not deterioration but acquired character.
