Strap for Constellation Quartz 24 Polished Red Gold / Supernova / Full Snow

The lug width of the Constellation 123.55.24.60.55.009 is 18mm. This measurement should be taken between the two lugs at their innermost point, perpendicular to the watch's axis. It is a precise specification with no tolerance: any 18mm strap will fit perfectly onto the original attachments.

For a rose gold Constellation, alligator (especially in cognac, honey, or burgundy tones) represents the most elegant choice, as the natural grain of the crocodile leather visually complements the warmth of rose gold. As a refined alternative, smooth calf leather in dark brown or black tones offers sophisticated minimalism. Shell cordovan in wine color is the ideal choice for those seeking soft and deep patina.

To change the strap, obtain a spring bar tool (special tool with blunt ends). Position the watch on a stable surface with the strap facing upward. Insert the tip of the spring bar tool into the small lateral hole of the lug, gently pushing downward to compress the internal spring and release the bar ends. The strap will come free. Repeat on the other side. To install the new 18mm strap, align the first lug, insert the bar into the slot and use the tool to compress the spring on the other side until it clicks into place.

Yes. Aftermarket 18mm straps made of alligator, calf, and cordovan offer superior artisanal quality compared to original Omega straps, thanks to access to specialized suppliers and bespoke craftsmanship. Ensure the new strap has an exactly 18mm lug width and that the spring bar holes are positioned correctly. Contact certified manufacturers who guarantee compatibility with Constellation lugs.

A fine leather strap (alligator, calf, shell cordovan) worn daily typically lasts 3-5 years before requiring replacement, depending on sun exposure, water contact, and frequency of wear. Vegetable-tanned leather tends to develop patina more rapidly (2-3 years of intensive use). An FKM rubber strap lasts 5-7 years. Regular maintenance with specialized creams and protection from moisture significantly extend strap life.
