Strap for Constellation Quadrella Quartz 25 Stainless Steel / Yellow Gold / MOP

The lug width of the Omega Constellation 1284.79.00 is 20 millimeters. This dimension is specific to this model and is determined by the width of the case lugs. When purchasing a replacement strap, ensure it is compatible with the 20mm size by measuring the perpendicular distance between the two shoulders of the case.

For the Constellation 1284.79.00, the best straps are made from natural alligator (beige, champagne, silver grey) or polished calf leather (black, burgundy). Alligator enhances the luminosity of the mother-of-pearl dial, while calf offers understated elegance and versatility. Avoid rubber or sports fabric straps, as the Constellation is a dress watch that requires refined materials consistent with its identity.

To change the strap, use a spring bar tool (a specialized watch tool). Position the tool in the small lateral slot of the spring bar (the metal spring that connects the strap to the case) and gently press to release the tension. Remove the spring bar and old strap. Insert the new 20mm strap into the lugs, align the spring bar and snap it into position. If you are unsure, consult a professional watchmaker.

Yes, you can use quality aftermarket straps as long as they are compatible with the 20 millimeter lug width. High-quality alligator or calf leather straps will not damage the case and offer aesthetic versatility. Milano Straps offers customizable 20mm straps online, or you can commission a bespoke strap from Casati Milano atelier for custom-made straps.

A high-quality leather strap (alligator or calf) typically lasts 2-4 years with moderate daily use. Durability depends on ambient humidity, frequency of use and care: dry the strap after water contact, avoid prolonged exposure to sunlight and extreme temperatures. Milano Straps straps are guaranteed for 18 months, while protective treatment with specific creams significantly extends the life of the strap.
