Strap for Constellation Manhattan 25 Quartz Stainless Steel / Sedna Gold / Silver Diamond / Diamond

The lug width (also called strap width) of the Omega Constellation 131.25.25.60.52.001 is 16mm. This measurement is critical for aftermarket strap compatibility. To verify it correctly, measure the inner distance between the two lugs (the metal protrusions on the case) using a calliper. The depth of the lug spaces is approximately 5mm, so the strap should not exceed 4mm in thickness to ensure smooth and stable insertion.

For the Constellation 131.25.25.60.52.001, an alligator leather strap remains the most harmonious and historically appropriate choice: the natural grain pattern dialogues perfectly with the geometric proportions of the case and the bimetallic steel-Sedna Gold effect. Alternatively, shell cordovan offers superior patina development over time, whilst vegetable-tanned leather is the sustainable option. For a more sporty interpretation, a canvas NATO strap provides an elegant contrast to the dress-watch design.

The process is straightforward and requires no specialised tools. Access the spring bars (small metal springs inside the lugs) using a gentle spring bar tool or even a small rounded rod. Compress one spring bar slightly towards the centre of the case to release one end of the strap, then extract the strap. Repeat from the opposite side. To install the new 16mm strap, align the holes with the spring bars, insert one end into the lug, compress the spring bar, and snap the opposite end into the opposite lug. Verify that both ends are fully seated and that the case sits stably.

Yes, any strap with a 16mm lug width is compatible with this model, provided the thickness does not exceed 4mm and the depth within the lugs allows smooth insertion. Straps crafted by Milano Straps are specifically tested to guarantee compatibility without forcing. Avoid generic straps that are too thick, as they may damage the lugs. Always verify that the seller explicitly confirms compatibility with the 16mm lug width.

The lifespan of a leather strap depends on material quality, daily use, and maintenance. A superior-grade alligator strap, such as those offered by Milano Straps, can last 3–5 years with moderate use, developing a splendid natural patina in the process. Shell cordovan is even more durable, with a service life of 5–7 years. Vegetable-tanned leather has a lifespan comparable to alligator. Regular maintenance—periodic cleaning, avoiding prolonged direct sunlight, keeping it dry—significantly extends useful life. Milano Straps provides an 18-month warranty on all handcrafted straps.
