The 20 mm lug width ensures proper proportionality and balanced visual appearance of this classic design.

Frequently asked questions

What is the lug width of the A. Lange & Söhne Lange 1 320.032?

The lug width of the Lange 1 320.032 is 20 mm. This measurement represents the internal distance between the two lugs of the case and must be strictly respected when choosing an aftermarket strap to maintain the aesthetic and functional integrity of the watch. A strap of different width compromises the delicate proportions of this model.

Which strap best suits the Lange 1 pink gold 320.032?

For the Lange 1 in pink gold, we recommend alligator in medium brown tones, calf leather with vegetable tanning in tan or cognac, or shell cordovan for those who intend to wear the watch daily. Alligator creates a sophisticated dialogue with the warmth of the case and develops a natural patina over time. Calf leather offers greater versatility, whilst shell cordovan provides exceptional wear resistance.

How do you change the strap on the Lange 1 320.032?

Changing the strap requires millimetre precision. Use a spring bar removal tool to gently lift the passant that fastens the lug to the case. Maintain constant and controlled pressure to avoid scratches on the pink gold. The new strap must feature passants compatible with the 20 mm width and must be threaded with equal care. If you are not experienced, consult a competent watchmaker.

Is an aftermarket strap compatible with the Lange 1 320.032?

Yes, provided the strap is specifically designed for a 20 mm lug width. A high-quality artisanal strap, crafted from premium leathers such as alligator or shell cordovan, does not compromise the authenticity or value of the watch. Rather, it represents an opportunity to personalise the model whilst maintaining correct dimensional compatibility. Casati Milano straps are constructed to sartorial specifications and guaranteed for 18 months.

What is the lifespan of a natural leather strap worn daily?

A high-quality leather strap, such as alligator or shell cordovan, subjected to routine maintenance and worn daily, provides a lifespan of 5-10 years before requiring replacement. Shell cordovan, thanks to its fibre density, tends to resist wear better. Longevity depends on intensity of use, climatic conditions, and the type of vegetable or chromium tanning employed. Periodic cleaning and occasional conditioning significantly extend the strap's life.
