Strap for 1815 Chronograph Pink Gold / Silver / Pulsometer

The A. Lange & Söhne 1815 414.032 features a lug width of exactly 20 millimetres. This measurement refers to the distance between the two inner lugs where the strap attaches to the case. It is essential to verify this measurement before purchasing an aftermarket strap, as an incorrect width would distort the case proportions and prevent proper attachment.

Alligator leather in cognac brown or tobacco tones represents the most reverential choice for this model, as the regular texture amplifies the luminosity of pink gold. Shell cordovan is a contemporary alternative that develops a deep patina over time, creating a compelling dialogue with the natural ageing of the gold. For a more formal and modern aesthetic, black alligator strap provides maximum visual contrast with the metal case.

The strap is secured by two spring bars that pass through the case lugs. To remove it, use a spring bar tool and position its small end under one bar from beneath, applying gentle inward pressure. The bar will retract, allowing extraction. Repeat on the opposite side. To install a new strap, align the holes on the new strap with the bars and reinsert them until you hear an audible click. Avoid using screwdrivers or improvised tools, which may scratch the lugs.

Yes, any strap with a 20mm lug width is technically compatible with the 414.032. However, given the watch's value and the specific case proportions, we recommend choosing superior-quality straps made from noble leathers such as alligator, shell cordovan, or vegetable-tanned leather. Low-quality straps may slip during wear or deteriorate prematurely, compromising the experience of this horological masterpiece.

Durability depends on leather quality and usage conditions. A high-quality handcrafted alligator or shell cordovan strap, worn daily without direct exposure to water, excessive perspiration, or prolonged humidity, typically lasts 3–5 years. Alligator tends to preserve longer due to its natural resilience, while cordovan develops surface creasing after 4–6 years of intensive use, though it remains functional. A vegetable-tanned leather strap lasts 2–3 years under normal conditions. To extend longevity, avoid frequent water exposure and apply leather conditioner every 12–18 months.
