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

The lug width of the Constellation 123.55.24.60.55.011 is 19 millimetres. This measurement represents the distance between the case lugs and must correspond exactly to the width of the compatible strap. You can measure it with a ruler or digital calliper, positioned perpendicularly between the two lugs.

For the Constellation in 18-carat rose gold, the most appropriate materials are alligator (for formal occasions), box-calf leather (for everyday versatility) and shell cordovan (for those seeking noble patina). Alligator with satin finishing creates the best aesthetic contrast with the polished rose gold, while cognac calf leather offers natural chromatic continuity.

Strap replacement requires the aid of a springbar tool or a thin, non-pointed rod. Position the watch with the case facing upwards, insert the tool into the lateral slot of the spring, compress gently to release the lug from its current seat, remove the old strap and insert the new one by aligning it with the lugs. Repeat the operation on the other lug. Precise and slow movements reduce the risk of scratching the case.

Yes, quality artisanal straps maintain and in some cases enhance the perceived value of the watch. Specialist brands using premium leathers (alligator, shell cordovan, selected calf) offer guaranteed 19mm compatibility without altering the original case. Always keep the original Omega strap should the Constellation be passed on to another owner, as it contributes to historical value.

An artisanal quality leather strap, subject to moderate daily wear (4-5 days per week), maintains structural and functional integrity for approximately 3-5 years. Duration varies based on material: shell cordovan resists longer thanks to fibre density, while thinner calves require more frequent maintenance. Exposure to moisture, sweat and UV rays accelerates ageing. Casati Milano provides an 18-month warranty on bespoke straps, with the possibility of regeneration through leather reconditioning.
