Strap for 1815 Tourbillon Pink Gold

The A. Lange & Söhne 1815 ref. 730.032 features a lug width of precisely 20 mm. This dimension is determined by the geometry of the 39.50 mm case diameter and the forged pink gold lugs. A compatible strap must measure 20 mm at the lug insertion point, with a tolerance of ±0.2 mm maximum to ensure secure attachment without play or excessive tension.

For the 1815 730.032 in pink gold, we recommend authentic alligator above all: its regular grain texture dialogues elegantly with the warm tone of the gold. Alternatively, superior quality vegetable-tanned calf leather represents a versatile and sustainable choice. Shell cordovan is excellent for those seeking chromatic complexity that ages beautifully. Heavy-duty canvas NATO straps offer the most practical solution for alternating formal and casual wear, though they are less formal than leather.

Strap replacement is achieved via the spring bars located at the ansa extremities. Use a dedicated tool (spring bar remover) to gently compress the spring bars and remove the old strap. Insert the new strap, align it with the lugs, and allow the spring bars to lock into the strap holes. We recommend performing this operation carefully to avoid damaging the case; a professional watchmaker remains the safest choice for a timepiece of such value.

Absolutely. High-quality artisanal straps, precisely measured at 20 mm, are entirely compatible with the 1815 730.032. Specialist brands and bespoke ateliers such as Casati Milano offer custom straps crafted to exact specifications, ensuring finishing and materials worthy of the German masterpiece. Selecting a premium aftermarket strap elevates the ownership experience without compromise.

Leather strap durability depends on material, tanning method, and usage patterns. Premium alligator or cordovan with vegetable tanning easily achieves 3–5 years of daily use before showing significant ageing signs. Vegetable-tanned calf typically lasts 2–4 years. The patina that develops—subtle creasing, colour variation—is a cherished characteristic of genuine leather, not a defect. Minimal maintenance (occasional cleaning, conditioning with natural creams) significantly extends longevity.
