The Saxonia 405.048F, seen from the bench

The A. Lange & Söhne Saxonia 405.048F embodies Saxon watchmaking tradition with geometric elegance and harmonic proportions. This model from the Saxonia collection, established in 1994, represents continuity with 1930s Glashütte masterpieces. The 41 mm yellow gold case features a crystalline white dial and signature Lange indices, powered by the L951.8 manual calibre with hours, minutes, small seconds, date and flyback chronograph. The movement, visible through a sapphire caseback, displays platinum bridges and Trois Quarts plate with perlage and barleycorn finishing. The 20 mm lug width provides versatility for strap selection while maintaining aesthetic coherence.

Frequently asked questions

What is the lug width of the A. Lange & Söhne Saxonia 405.048F?

The Saxonia 405.048F features a 20 mm lug width, measured from the centre of one lug to the centre of the opposite lug, excluding case thickness. This is the standard width for this category of elegant timepieces and enables a versatile selection of compatible straps.

Which strap pairs best with the A. Lange & Söhne Saxonia 405.048F?

Dark brown or stone grey alligator represents the natural choice for the Saxonia 405.048F in yellow gold: the fine texture and regular graining emphasise the case's restraint. Alternatively, vegetable-tanned calf leather offers a more monolithic, velvety surface, whilst a yellow gold 18 kt bracelet ensures complete metallurgical coherence.

How do I change the strap on my A. Lange & Söhne Saxonia 405.048F?

Strap change is performed by removing the lateral lugs from the case using a dedicated tool (spring bar tool). Position the watch on a stable base, insert the blunt end of the tool into the lug aperture and push gently until the internal spring releases. The new strap is inserted by reversing the procedure, ensuring the lugs are completely secured.

Can I use an aftermarket strap with my A. Lange & Söhne Saxonia 405.048F?

Yes, the Saxonia 405.048F is compatible with any quality artisanal strap featuring a 20 mm lug width. We recommend selecting premium leathers and finishes that respect the elegance of the yellow gold case, such as alligator, vegetable-tanned calf or shell cordovan. A high-quality aftermarket strap can further enhance the piece.

How long does a leather strap last on my A. Lange & Söhne Saxonia 405.048F?

The lifespan of a leather strap depends upon usage and care. A quality alligator or calf, worn intermittently and protected from excessive moisture, can last 5–8 years. Natural leather develops a patina over time, enriching the aesthetic of the piece. Standard warranty against manufacturing defects is 18 months.
