Strap for Constellation Quartz 24 Red Gold / Diamond / MOP Star

The lug width of the Constellation 123.55.24.60.05.004 is 18 millimetres. This measurement is critical to ensure compatibility with aftermarket straps: every strap must have lugs sized exactly at 18mm. Always verify the measurement with a digital calliper placed between the lugs, from the inner point of one to the other, excluding the case shoulders.

The ideal strap depends on the desired aesthetic and use. For maximum elegance, a cognac or dark brown alligator strap enhances the rose gold without competing with it. For those who appreciate the evolution of patina over time, a vegetable-tanned calf leather in burgundy or brown tones offers an aesthetic ageing experience. A reinforced option is shell cordovan in burgundy, which guarantees superior durability and a visual effect of depth. The choice depends on the balance between formality, use and desire for visual evolution.

Changing the strap requires a spring bar tool (a small tool with tapered tips) available at watch retailers. Place the timepiece on a soft, stable surface. Insert the tip of the spring bar tool into the small hole present under the lug, gently compress the spring to release the pin. Repeat on both sides. Insert the pin of the new strap, ensuring that the spring clicks into position (it should be audible). Check that the strap is stable on both attachments.

Yes, provided the strap is specifically designed for an 18mm lug width. Always verify the strap specifications before purchase. Aftermarket straps of artisanal quality, made in alligator, calf leather or shell cordovan, guarantee perfect compatibility and an aesthetic experience equal to or superior to original straps, thanks to the possibility of personalisation in leather, colour and stitching.

The lifespan of a leather strap depends on the material and use. An alligator or calf leather strap, worn daily in moderate humidity conditions, has a typical lifespan of 3-5 years. Shell cordovan, thanks to its superior fibre density, can last 6-8 years. Occasional use can significantly extend the useful life. Maintenance with leather-specific balms (not generic greases) and drying after humidity exposure will slow down ageing and maintain aesthetics over time.
