The Lange 1 115.032, seen from the bench

The A. Lange & Söhne Lange 1 115.032 in pink gold (41.90 mm) is a German watchmaking icon introduced in 1994, featuring an asymmetrical dial with large date window, small seconds counter, and vertically oriented power reserve indicator. Powered by the caliber L901.2 movement beating at 28,800 vph with 72-hour power reserve and double mainspring, the silver dial displays applied gold indices and thermal-printed numerals. The 22 mm lug width is architecturally calculated to proportion the asymmetrical dial and distribute wrist tensions effectively across the curved lugs.

Frequently asked questions

What is the lug width of the A. Lange & Söhne Lange 1 Ref. 115.032?

The A. Lange & Söhne Lange 1 115.032 features a 22 mm lug width. This dimension is not arbitrary—it responds to the geometric proportions of the 41.90 mm case and distributes tension more effectively across the wrist during movement. Always verify lug width using a digital calliper positioned perpendicularly at the midpoint between the lugs.

Which strap material is best suited for the A. Lange & Söhne Lange 1 115.032?

For the 115.032 in rose gold, we recommend alligator (formal Saxon elegance), vegetable-tanned calf leather (developing golden patina over time), or natural rubber for summer months. Pearl-grey alligator achieves the finest visual equilibrium, whilst cognac calf amplifies the rose-gold tone of the case. Avoid synthetic materials: this watch deserves leather that ages with dignity and character.

How do you change the strap on an A. Lange & Söhne watch?

Use a spring bar removal tool to extract the elastic pins. Secure the lug firmly, position the flat end of the tool beneath the small metal support, apply gentle inward pressure to compress the spring and remove the lug. Repeat on the opposite horn. Install the new strap by reversing the procedure, ensuring the lug is fully seated in both holes without forcing.

Is an aftermarket strap compatible with the Lange 1 115.032?

Yes, provided the lug width measures exactly 22 mm. Milano Straps offers bespoke straps specifically engineered for this width. Contact Casati Milano for personalised consultation: you select the leather, follow production via WhatsApp, and receive an 18-month warranty against manufacturing defects.

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

A quality strap in alligator or vegetable-tanned calf leather typically lasts 3–7 years with daily wear. Longevity depends on usage frequency, humidity exposure, and maintenance practices. Milano Straps' bespoke straps are engineered for longevity through robust construction and superior stitching: periodic cleaning and light conditioning further extend the strap's service life considerably.
