Strap for Lange 1 Tourbillon Perpetual Calendar Pink Gold

The A. Lange & Söhne Lange 1 720.032 features a lug width of 22mm. This specific measurement is intrinsic to the case geometry and should be measured by positioning a digital calliper between the lugs, drawing a perpendicular line from the lower groove base to the upper base. Millimetre precision is essential to ensure perfect fit and eliminate lateral play during wear. Any aftermarket strap must rigorously respect this dimension to guarantee proper compatibility and natural strap curvature at the attachment points.

For the rose gold 720.032, Mississippi alligator represents the finest choice: its refined grain and natural texture amplify the austere elegance of the case. Alternatively, Italian calf with vegetable tanning develops caramel and tobacco patina that mirrors the metal's warmth. Japanese shell cordovan offers mirror-like patina that contrasts nobly with the case's formality. We advise against technical rubber or pastel-coloured straps: the 720.032 demands visual weight that anchors the timepiece to the wrist. Ideal colours include tobacco brown, antracite black, aged bordeaux, or bottle green with developed patina.

The 720.032 strap is changed using a watchmaker-grade spring bar tool. Position the tool in the lower lug groove, press downward to compress the spring pin, then gently extract the spring bar. Repeat for the opposite lug. When reinstalling the new strap, ensure the spring bar is positioned through both lugs before releasing pressure. The procedure demands precision to avoid case scratches. Many collectors entrust this operation to a specialist watchmaker for high-value pieces.

Yes, installing a quality aftermarket strap on a 720.032 is entirely feasible, provided it is 22mm lug width. Artisanal straps in Tuscan leather, alligator, or shell cordovan offer elegant alternatives to the original strap. Verify that the manufacturer explicitly states 22mm compatibility and employs quality construction techniques (vegetable tanning for natural leathers, hand-finished edge painting). Milano Straps provides 22mm straps specifically engineered for this case size, with warranty coverage on manufacturing defects.

The lifespan of a vegetable-tanned leather strap ranges from 2 to 5 years depending on wear intensity, climate conditions, and maintenance. Alligator generally lasts longer (4–6 years) due to natural skin density. A strap subjected to daily use, sun exposure, and high humidity will age more rapidly. The developed patina is nevertheless a desirable aspect for collectors, as it testifies to the watch's actual use. To extend strap lifespan, avoid prolonged water contact, apply natural water-resistant treatments, and rotate usage between multiple straps. With Casati Milano, every strap includes an 18-month warranty covering manufacturing defects, independent of natural leather wear.
