Strap for Constellation Quartz 27 Stainless Steel / Red Gold / MOP

The lug width of this model is exactly 20 millimetres. This measurement refers to the distance between the inner edges of the two vertical protrusions on the case where the strap is inserted. Always verify with a digital calliper before ordering an aftermarket strap.

For this ladies' model with mother-of-pearl dial we recommend cognac brown alligator or Italian vegetable-tanned calf leather. Alligator creates defined contrast with the mother-of-pearl, while calf develops natural patina over time. Avoid excessively dark or colourful materials that would compete with the dial's luminosity.

Remove the strap using a springbar tool to release the lateral pins. Position the new strap by aligning the holes with the pins and reinsert the springbars into position. If you lack experience, consult a qualified jeweller to avoid scratching the case.

Yes, any strap with a 20mm lug width is technically compatible. However, consider proportions: the 27mm diameter requires straps with contained thickness (max 4.5mm) and elegant width, not heavy. Milano Straps offers 20mm straps specifically sized for watches in this category.

A quality alligator strap, worn daily, typically lasts 2-4 years before showing significant wear. Vegetable-tanned calf tends to develop patina sooner, but remains functional longer if subjected to periodic maintenance. Prolonged sun exposure accelerates ageing. Casati Milano guarantees 18 months on custom straps and provides conservation advice.
