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

The Omega Constellation 123.25.24.60.55.003 has a lug width of 19mm. This measurement is critical for the compatibility of any aftermarket strap. Measure the distance between the two lugs (the terminals protruding from the case) to verify that your chosen strap is compatible. Even a 0.5mm deviation would compromise the fit.

For the 123.25.24.60.55.003, we recommend authentic alligator (with a scale texture that reflects light like the mother-of-pearl dial) or box calf (with a hammered finish that emphasizes the craftsmanship). Both materials, in cognac brown or black, create an elegant contrast with the two-tone case. We advise against synthetic materials as they contradict the identity of a refined wristwatch.

The strap is secured by two spring bars that connect the case lugs to the strap itself. Use a spring bar tool to compress the internal spring of the pin, then gently extract it. Slip the new strap through the case perimeter and reinsert the pins until they click into place. If you are not experienced, consult a trusted watchmaker: an incorrect operation could damage the lugs.

Yes, provided the strap was originally specified for the 19mm lug width. However, we recommend verifying the condition of the leather: a vintage strap may have edge wear or loss of elasticity. Milano Straps offers new 19mm straps, customizable in color, initials, and stitching thread, available online and made to order at the Casati Milano atelier.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 2-4 years with daily wear, depending on climate, humidity, and frequency of use. The leather wears primarily at the spring bar attachment point and at the buckle. Milano Straps straps, made with premium leathers, include an 18-month warranty and can be replaced or repaired at the Casati Milano atelier, which also offers finishing and maintenance services.
