Strap for Constellation Quartz 24 Brushed Yellow Gold / Diamond / Champagne Supernova

The Omega Constellation 123.55.24.60.58.001 has a lug width of 16 mm. This dimension is critical for compatibility: an undersized strap (14-15 mm) will fit too tightly, while an oversized one (17-18 mm) will have excessive play. Always measure with a digital caliper between the internal attachment points of the case.

For the Constellation 123.55.24.60.58.001, we recommend a dark brown or black alligator strap, which enhances the formal purity of the case. A refined alternative is vegetable-tanned calf leather, which develops a noble patina over time. The silver pearl dial pairs particularly well with warm earth tones or graphite, avoiding blue or red which would create chromatic conflict.

To change the strap, position the watch on a flat surface and use a springbar tool (the small fork-shaped tool used by watchmakers) to gently lift the spring bar pin that secures the strap to the case. Remove the old strap by pulling it laterally, then insert the new one by aligning the holes with the pins and press until you hear a click. If you don't have the tool, consult a watchmaker: the cost is minimal and the risk of damaging the case is eliminated.

Yes, a 16 mm aftermarket strap is completely compatible with the 123.55.24.60.58.001. Make sure the strap is made from quality material (alligator, calf, shell cordovan) and that the lugs are correctly sized to leave no gaps. Artisanal straps from milanostraps.it are specifically optimized for Omega models with 16 mm lug width, with finishes and thicknesses that respect the original proportions.

A quality leather strap (alligator or calf) on a watch worn daily typically lasts 3-5 years before requiring replacement or restoration. Longevity depends on humidity exposure, sweat pH, and climatic conditions. Vegetable-tanned calf tends to last longer thanks to the natural tannin resistance, while alligator is slightly more delicate. The Casati Milano atelier offers an 18-month warranty on bespoke straps, covering any manufacturing defects.
