Strap for Constellation Quartz 25.5 '95 Stainless Steel / Blue

The Omega Constellation 1572.40.00 has a lug width of 20mm, the standard width for the Swiss women's segment in the 1990s. This measurement refers to the distance between the two spring bars that hold the strap on the case. All compatible straps must be 20mm to ensure precise installation without excessive play on the 25.50mm case.

The best strap depends on use and personal preference. Alligator is the most authentic choice: its horizontal grain echoes the geometry of the integrated Manhattan bracelet. A dark brown vegetable-tanned calf offers daily versatility with a patina that ages elegantly. For sport use, a satin technical rubber strap ensures practicality without sacrificing the elegance of the steel case.

The change requires a spring bar tool — a specific instrument that allows you to compress the inner pins and extract them from the case. Gently position the tool under the pin, push to compress the spring, then remove the old strap. Insert the new strap by aligning it with the case lugs and release the tool so the pin returns to position. A simple operation but one that requires care not to scratch the case: if inexperienced, it is advisable to consult a watchmaker.

Absolutely yes. Any aftermarket strap with a 20mm lug width is compatible with the 1572.40.00. Milano Straps artisanal straps, crafted in alligator, vegetable-tanned calf, rubber and other materials, are designed specifically for this width and offer superior build quality compared to standard factory straps, with customizable details such as initials and stitching thread.

Durability depends on material and use. High-quality vegetable-tanned alligator lasts an average of 5-7 years with daily wear, developing a fascinating patina over time. Softer calf may require replacement after 3-4 years of constant wear. Technical rubber is more durable — up to 8-10 years — but less versatile aesthetically. With seasonal rotation among different straps, the longevity of each extends significantly. Milano Straps offers an 18-month warranty on all bespoke straps.
