Strap for Lange 1 Tourbillon Homage to F.A. Lange

The A. Lange & Söhne Lange 1 722.050 features a lug width (measuring distance between the lugs) of 20 mm. This dimension is consistent across all construction variants of this model and is compatible with any strap specifically manufactured for 20 mm lugs.

For the 722.050 in Honey Gold, we recommend alligator straps in dark brown or medium-dark chocolate tones, which create warm contrast with the gold; calfskin with vertical grain in similar shades for daily versatility; shell cordovan in burgundy or cognac for those desiring accelerated patina and vintage character. Avoid cool chromatics (blue, grey) that clash with the gold's warmth.

The Lange 1 strap is changed via standard spring bars (lug bars). Using a spring bar removal tool, press the internal pin to release, withdraw the bar from its seat, and insert your new strap. For models equipped with a deployante clasp, ensure the replacement strap includes an equivalent mechanism or transfer the original deployante from your previous strap.

A strap crafted from superior leather (alligator, shell cordovan, vegetable-tanned calfskin) typically lasts 3–5 years with daily wear, subject to climate, humidity, perspiration, and maintenance. Leather ages naturally, developing patina and character; structural deterioration advances more slowly on vegetable-tanned leathers. Casati Milano guarantees 18 months against manufacturing defects.

Yes. Any wristwatch with a 20 mm lug width is compatible with straps designed for this dimension. Always verify your model: consult original documentation, measure the lug-to-lug distance directly, or contact your brand's customer service to confirm compatibility before purchasing.
