Strap for Richard Lange Perpetual Calendar Terraluna Pink Gold

The lug width of the Richard Lange 180.032 is 22 mm. This is the distance measured between the two lugs (attachment points) on the case. To verify the correct measurement, position a digital caliper from the centre of one lug to the centre of the other lug, keeping the measurement parallel to the watch's axis.

For a timepiece of this constructive and material stature, we recommend alligator in natural or dark brown coloration, which echoes the geometric precision of the dial. Alternatively, vegetable-tanned calf leather offers authenticity and develops patina over time. For daily versatility, a technically sophisticated structured rubber allows practicality without aesthetic compromise. We advise against sporty or casual strap categories, which would not honour the nobility of the rose gold case.

For a timepiece of this value, we strongly recommend entrusting the strap change to a qualified watchmaker. If you choose to proceed independently, use a spring bar tool to gently lift the elastic pin that secures the strap to the case lugs. Proceed slowly and with caution to avoid scratching the rose gold case. Insert the new strap by aligning the holes with the lugs, pressing the elastic pin until it locks on both sides.

Yes, any strap with a 22 mm lug width is compatible with the 180.032. However, not all 22 mm sizes are constructed with the precision and quality this watch deserves. We recommend selecting straps made by manufacturers specialising in fine leather (alligator, calf, shell cordovan) or structured technical rubber, avoiding standardised commercial products that do not reflect the value of the rose gold case.

The lifespan of a leather strap depends on usage, care, and leather type. A high-quality alligator or calf strap, worn moderately and maintained correctly, maintains structural integrity for 3–5 years of regular use. Vegetable-tanned leather develops natural patina and regains suppleness over time. To extend strap life, avoid prolonged exposure to perspiration, direct water, and intense sunlight. Structured rubber typically resists wear for 5–7 years before showing signs of ageing.
