Frequently asked questions

What is the lug width of the A. Lange & Söhne 1815 404.047?

The 404.047 features a lug width of 22mm. This measurement is specific to the model and is compatible exclusively with straps manufactured to this specification. You can verify it by measuring straight across from one lug hole to the other using a digital calliper.

Which strap is recommended for the A. Lange & Söhne 1815 404.047?

For the pink gold 404.047, black alligator in fine grain is the canonical choice. However, Tuscan vegetable-tanned calf leather in Cognac or Dark Brown tonalities offers natural chromatic harmony and develops authentic patina over time. For formal occasions, shell cordovan provides uncompromising robustness and timeless elegance.

How do I change the strap on an A. Lange & Söhne timepiece?

The strap is changed by extracting the spring bars (lug pins) from the lug seatings using a specialised extraction tool. DIY work on watches of this calibre is not recommended. Casati Milano offers professional strap replacement service in the atelier, with post-operative inspection of case and movement.

Can I use an aftermarket 22mm compatible strap on my 404.047?

Yes, provided it is manufactured to 22mm lug width specification. The tolerance for a 22mm lug is ±0.5mm. We recommend verifying fit manually before ordering. With Casati Milano, we measure your timepiece via WhatsApp to guarantee perfect compatibility.

How long does a leather strap last on an A. Lange & Söhne 1815 404.047?

Longevity depends on material and wear patterns. Well-maintained alligator lasts 5–7 years in daily use. Vegetable-tanned calf operates on 4–5 year cycles before surface regeneration is required. Shell cordovan reaches 10+ years. Casati Milano provides 18-month manufacturing guarantee and heritage restoration services.
