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

The Omega Constellation 123.25.24.60.58.001 has a lug width of 18mm. This is the actual space between the lugs of the case, where the strap must fit. It is essential to measure correctly with a caliper, excluding the lateral protrusions of the case, to ensure a precise fit without lateral play.

Vegetable-tanned alligator is the archetypal choice for the Constellation 123.25.24.60.58.001: the natural dorsal spines of the stitching create geometric patterns that respond to the watch's refined character, while the natural patina will improve over the years. Other valid options are madras box calf for sober elegance, shell cordovan for extraordinary durability, and NATO straps for casual versatility.

Changing the strap requires using a tool to remove the spring bars (pressure springs) that secure the strap to the lugs. Position the watch on a soft surface, locate the spring bars at the sides of the lugs (18mm), and gently compress the spring using a dedicated tool to release it. Remove the old strap, insert the new one, and press the spring bars back until they click into place. If you are unsure, entrust the task to a specialized workshop.

Yes, it is possible to use an 18mm aftermarket strap compatible with the Constellation 123.25.24.60.58.001, provided the lug width matches exactly 18mm. Always verify the measurement before purchase. Milano Straps artisan straps have been developed to guarantee precise compatibility and tailored construction quality on this Omega collection.

A natural leather strap under daily use typically lasts 18-36 months, depending on the quality of the leather, frequency of use, and maintenance. Vegetable-tanned alligator straps age beautifully, developing natural patina. Shell cordovan offers superior durability, up to 5 years under normal conditions. The 18-month warranty on Casati Milano straps covers manufacturing defects, not natural leather wear.
