Strap for Constellation Quartz 27 Polished Stainless Steel / Diamond / MOP

The lug width is 18 millimetres. This measurement represents the space between the case lugs and is essential for choosing a compatible strap. To measure it correctly, position a metal ruler directly between the lugs without including the lug pin protrusion itself.

The best pairing depends on your use case. Brown alligator amplifies the elegance and sensuality of the case. Black shell cordovan is ideal for those seeking extreme durability and formal patina development over time. Vegetable-tanned calf leather is perfect for those who appreciate the natural evolution of leather. For summer, cream-white NATO offers freshness and practicality.

The change is straightforward: gently remove the pins connecting the strap to the case using a dedicated pin removal tool. Once the pins are removed, the old strap comes free immediately. Insert the new strap by reinserting the pins. No permanent modification is necessary; the process is reversible in seconds.

Yes, the 18-millimetre lug width is a standard size used by many women's watches. However, always verify the lug width of your second watch before purchasing. Brands such as Omega, Cartier, Longines and many others offer models with this specification.

Durability depends on the material and usage. Vegetable-tanned calf typically lasts 3–5 years with daily wear, developing beautiful patina over time. Shell cordovan can last 10–15 years or more, thanks to the density of the leather. Alligator resists 5–7 years. Factors such as humidity, sun exposure and frequency of use significantly influence longevity.
