Frequently asked questions
What is the lug width of the A. Lange & Söhne Saxonia 310.050?
The lug width of the Saxonia 310.050 is 20 mm. This measurement is constant across all Saxonia collection models and represents the optimal proportion relative to the 38.50 mm case diameter. To verify it, measure the distance between the two lugs on the case shoulders.
Which type of strap pairs best with the Saxonia 310.050?
Alligator in dark cognac tones represents the canonical choice, as the natural reptile texture communicates sophistication without competing visually with the dial. Vegetable-tanned calf offers a more informal aesthetic with a natural patina that develops over time. For summer wear, NATO straps in silk or heavy cotton provide practicality, whilst shell cordovan in burgundy creates bold contrast with the honey gold.
How do I change the strap on my A. Lange & Söhne Saxonia 310.050?
The Saxonia 310.050 uses standard spring bar attachments. Remove the bars by pushing inward with a spring bar tool, then slide out the old strap. Insert the new strap, ensuring the side holes in the leather align perfectly with the lugs. Reinsert the spring bars until you hear a click. If unfamiliar with the process, consult a qualified watchmaker.
Can I use an aftermarket 20 mm strap on my Saxonia 310.050?
Yes, any strap with a 20 mm lug width is mechanically compatible. However, from an aesthetic standpoint, we recommend straps crafted from equivalent quality materials (alligator, vegetable-tanned calf, shell cordovan). The thickness at the attachment point must be precise to avoid lateral play between the lug and strap.
How long does a leather strap last on an A. Lange & Söhne Saxonia 310.050?
Longevity depends on material and usage patterns. An alligator strap typically lasts 4–6 years with daily wear; vegetable-tanned calf resists 3–4 years due to lower density; shell cordovan exceeds 7 years owing to the natural compactness of the leather. Sun exposure, humidity, and perfume accelerate ageing. Regular maintenance (annual cleaning and conditioning) significantly extends useful life.
