The Heritage

The Lange 1 was introduced in 1994 as the first model of the renaissance of A. Lange & Söhne after German reunification. It features the in-house Caliber L121.1 manual-winding movement with indication of hours, minutes, small seconds, big date and power reserve. The case presents the characteristic asymmetric dial layout with the big date positioned at 1 o'clock.

FAQ

What is the lug width of the A. Lange & Söhne Lange 1 191.062?

The reference 191.062 is fitted with a 20mm lug width: this is the internal distance between the two lugs on the case, measurable with a caliper after removing the original strap. All compatible straps must have a 20mm attachment.

What is the best strap for the Lange 1 191.062 in platinum?

For a 950 platinum case, smooth alligator leather in black or dark anthracite gray represents the most coherent pairing: the texture of the belly does not compete with the asymmetrical dial but emphasizes its presence. Box-calf leather in cognac or midnight blue is the second most appreciated choice among collectors.

How do you change the strap on an A. Lange & Söhne Lange 1 191.062?

Replacement is accomplished using standard 20mm spring bars. It is advisable to use a case opener with a flat tip or a thin-bladed watchmaker's screwdriver, inserting the tool into the slot on the lug and gently prying to release the bar. On a platinum case, it is preferable to protect the lugs with soft adhesive tape before the operation.

Are there aftermarket straps compatible with the Lange 1 191.062?

Yes: any strap with a 20mm attachment is technically compatible. Milano Straps offers a selection of artisanal straps in various leathers and finishes, all with 20mm lugs, compatible with reference 191.062. The Casati Milano atelier also offers custom-made straps with personalized leather selection.

How long does a leather strap last on an A. Lange & Söhne Lange 1 191.062?

Durability depends on the leather and conditions of use: quality alligator, protected from moisture and rotated with a second strap, maintains structural integrity and vivid patina for 3-5 years. Box-calf leather has a slightly shorter lifespan but develops more distinctive patina over time. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
