The Constellation 131.25.28.60.99.001 (aka: 13125286099001), seen from the bench

The Omega Constellation Manhattan 28 Quartz Stainless Steel Sedna Gold (ref. 131.25.28.60.99.001) features a 28mm case combining Sedna Gold (18-karat red gold) with stainless steel, housing an Omega 4061 quartz movement. The distinctive ice blue meteorite dial showcases the iconic Constellation griffes framing the sapphire crystal and the integrated Manhattan bracelet with geometric segments. The 20mm lug width connects the case to the strap, positioning this model within the modern Constellation mini category with vintage-inspired proportions.

Frequently asked questions

What is the exact lug width of the Omega Constellation 131.25.28.60.99.001?

The Omega Constellation 131.25.28.60.99.001 has a lug width of 20mm. This measurement is critical when purchasing aftermarket straps: it does not correspond to the case diameter (28mm), but rather represents the space between the lugs where the strap is inserted. Always verify this dimension with a caliper before ordering.

What is the best strap for the Omega Constellation 131.25.28.60.99.001 with meteorite dial?

For the meteorite dial (natural grey-black-bronze), we recommend a black alligator or medium brown regenerated calf strap, both with a deployant clasp. Alligator offers regular and geometric grain that echoes the integrated Manhattan bracelet; calf develops natural patina over time. Avoid light shades that would visually compete with the meteorite.

How do you change the strap on the Omega Constellation 131.25.28.60.99.001?

The strap is attached to the lugs via screws (not simple pass-through pins). You will need a specialized watchmaker's screwdriver to remove the tiny screws with precision, without risking damage to the case or the lugs. We recommend contacting an Omega certified watchmaker or Milano Straps for installation, ensuring proper tightening and alignment.

Are all 20mm aftermarket straps compatible with the 131.25.28.60.99.001?

No. Although the lug width is 20mm, the case with integrated lugs requires attention: the strap must not interfere with the four leonine claws or the case thickness. We recommend purchasing from specialized retailers (such as Milano Straps) that guarantee verified compatibility and perfect fit with the integrated Manhattan bracelet.

How long does a leather strap last on an Omega Constellation 28mm worn daily?

A high-quality artisan alligator or calf strap lasts 4-7 years with daily wear, developing natural patina and character. Shell cordovan resists longer (7-10 years). Durability depends on tanning method (vegetable > chromatic), frequency of exposure to moisture/sweat, and maintenance. Milano Straps offers an 18-month warranty on custom straps.
