Frequently asked questions
What is the lug width of the A. Lange & Söhne Saxonia 309.031?
The Saxonia 309.031 features a lug width of 20 mm, specifically calibrated for this reference. Measurement must be taken internally between the spring bar seats with millimetre precision. A strap of different width (18 or 22 mm) will not fit correctly into the case lugs.
What is the best strap for the A. Lange & Söhne Saxonia 309.031?
For the Saxonia 309.031 in pink gold, alligator is the noblest choice, followed by vegetable-tanned calf and shell cordovan. These materials respect the dress watch character of the case and harmonise beautifully with the patina of pink gold. Avoid NATO straps or rubber, which would contradict the formal vocation of the piece.
How do I change the strap on my A. Lange & Söhne Saxonia 309.031?
The strap is replaced by carefully removing the spring bars with a professional tool, available in dedicated kits. For a Saxonia of this calibre, it is advisable to entrust the operation to a qualified watchmaker, avoiding damage to the pink gold case. Casati Milano also provides this service in their atelier.
Does a quality aftermarket strap for the Saxonia 309.031 compromise the piece's value?
No, if constructed to equivalent standards and with noble materials (alligator, calf, cordovan). A high-quality strap—produced by specialised manufactories—actually represents an aesthetic and comfort improvement, provided the original strap is retained. Reversibility is always a recommended practice for collectors.
How long does a leather strap last on the A. Lange & Söhne Saxonia 309.031?
A high-quality leather strap (alligator, cordovan, vegetable-tanned calf) typically lasts 3-5 years with constant daily wear, depending on climate and frequency of use. Leather fears excessive humidity and prolonged dry heat. Casati Milano provides straps with an 18-month warranty on manufacturing defects and recommends periodic maintenance with natural oils.
