Frequently asked questions

What is the lug width of the A. Lange & Söhne Lange 1 Ref. 116.050?

The lug width of the A. Lange & Söhne Lange 1 Ref. 116.050 is 22 mm, measured internally between the case lugs. This width is specific to the model and requires straps constructed precisely for 22 mm. Straps of 20 mm or 24 mm will not fit correctly with the case attachments.

What is the best strap for the A. Lange & Söhne Lange 1 Ref. 116.050?

For the 116.050 in Honey Gold, we recommend dark brown alligator or vegetable-tanned calf leather in cognac tones. Alligator offers classical elegance and predictable patina; vegetable-tanned calf provides more character in texture. Avoid cool colours such as grey or navy blue, which do not harmonise with the warmth of yellow gold. For maximum formality, shell cordovan in burgundy represents the rare collector's choice.

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

The strap is changed using a spring bar removal tool. Position the watch with the lug side visible, insert the tool into the designated opening and gently lever to extract the spring bar. Replace the old strap with the new one and reinsert the spring bar. If you are not experienced, consult a qualified watchmaker: on a Lange 1, precision is essential to avoid damaging the case finishes.

Is an aftermarket strap compatible with the A. Lange & Söhne Lange 1 Ref. 116.050 of good quality?

An aftermarket strap of artisanal quality – such as those made by Casati Milano – is perfectly compatible and often superior to original straps in terms of customisation and durability. The key is to verify that it is constructed for exactly 22 mm lug width and that it uses excellence leather (alligator, vegetable-tanned calf, cordovan). A bespoke strap offers production guarantees and the opportunity to choose colour, finish and deployante according to your preferences.

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

A quality leather strap has an average lifespan of 3 to 5 years with daily wear, provided it is treated with care. Alligator and cordovan deteriorate more slowly than common calf leather. Longevity depends on factors such as ambient humidity, frequency of wear and maintenance: regular cleaning with a damp cloth and storage in a dry environment prolong the strap's life. Casati Milano offers an 18-month warranty on manufacturing defects.
