Frequently asked questions

What is the lug width of the A. Lange & Söhne 1815 206.025?

The A. Lange & Söhne 1815 206.025 features a lug width of 19mm. This measurement must be taken precisely between the outer edges of the lugs using a digital calliper, positioned parallel to the lug axis. Any strap intended for this model must have an external width of exactly 19mm to ensure a secure, rattle-free fit.

What is the best strap for the A. Lange & Söhne 1815 206.025?

The optimal choice depends on intended use. For formal occasions, a polished black alligator strap with platinum deployante represents perfect synergy with the platinum case. For long-term wear, shell cordovan offers superior durability and patina development. Vegetable-tanned leather provides the most versatile profile, compatible with both formal and smart-casual attire. Rubber with deployante is the functional summer solution.

How do you change straps on an A. Lange & Söhne 1815 206.025?

Strap removal is accomplished by extracting the spring bars connecting the lugs to the case. These bars are typically accessible from the caseback or directly from the case sides. Specialised spring bar tools are recommended to avoid damage to the lugs or passants. Casati Milano provides technical support for this operation, ensuring precision and safety.

Is an aftermarket strap compatible with the 206.025?

Yes, provided it has been manufactured specifically for a 19mm lug width. Compatibility is determined by exact lug width, not by watch brand. Milanostraps.it maintains a dedicated collection of 19mm straps, verified and tested for precise fit. Engaging specialist producers guarantees superior construction quality and long-term durability.

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

Lifespan depends on material and usage patterns. Premium alligator resists 5–7 years of daily wear before requiring replacement due to natural fatigue. Shell cordovan may endure 7–10 years due to superior fibre density. Vegetable-tanned calf, more delicate, typically requires replacement every 4–5 years under regular use. Casati Milano provides an 18-month warranty on manufacturing defects, regardless of material selected.
