Frequently asked questions

What lug width does the A. Lange & Söhne Saxonia 384.031 require?

The A. Lange & Söhne Saxonia 384.031 requires a strap with a lug width of 18 millimetres. This width is specific to the model and ensures a perfect fit without play or forcing. We recommend verifying the measurement with callipers before ordering.

Which strap material pairs best with the Saxonia 384.031 in rose gold?

For a timepiece of this calibre, we recommend American alligator (natural grain) or calf leather with vegetable tanning. Alligator amplifies the discrete luxury charge of rose gold, whilst calf leather ages with dignity, developing a natural patina. We advise against shell cordovan (overly formal) and smooth leathers (which create visual flatness).

How do you change the strap on the A. Lange & Söhne Saxonia 384.031?

The Saxonia 384.031 features straight lugs with a standard spring bar system. Obtain two spring bar tools or consult a watchmaker. Insert the tool into the small lateral opening of the lug to compress the pin, remove the old strap, align the new strap with the lug hole, and allow the pin to snap into place. The operation requires care to avoid scratching the rose gold.

Which aftermarket straps are compatible with the 384.031?

Any strap with an 18mm lug width is compatible. Milano Straps offers a curated collection of artisanal leathers (alligator, calf, shell cordovan) and technical textiles with deployante, 3-link buckle or passant systems, available in various colours. We recommend Casati Milano's consultation to select the material that resonates with the rose gold casing.

How long does a leather strap last on a regularly worn watch?

A high-quality artisanal strap with vegetable tanning typically lasts 3–5 years on a daily-worn timepiece. Humidity, perspiration, and frequency of wear influence durability. Milano Straps straps include an 18-month warranty against manufacturing defects. Regular maintenance (cleaning, drying, rest periods) extends the leather's lifespan.
