Strap for Constellation Manhattan 25 Quartz Yellow Gold / MOP / Diamond

The Constellation 131.55.25.60.55.002 features a 16 millimeter lug width. This measurement is specific to Omega's female models of this generation and represents the standard construction specification for the 25mm case. The measurement should be taken inside the lug area, from inner edge to inner edge, to ensure maximum precision when selecting a replacement strap.

For a Constellation 131.55.25.60.55.002 in yellow gold, alligator remains the most refined and proportionate choice: the classic grain amplifies the precious nature of the gold with elegant chromatic contrasts. Vegetable-tanned calf offers versatility and develops a magnificent patina with age. Shell cordovan provides structure without weight, maintaining the tapered profile of the case. Avoid rubber and silicone for this precious version, as they contradict the aesthetic purpose of the timepiece.

Strap replacement requires removing the springbars that secure the strap to the lugs. Use a dedicated tool (springbar remover) to slide the pin out from the small lateral groove: the pin will retract, allowing the strap to slide off. Position the new 16mm strap under the lugs and reinsert the pin from the same position, ensuring that the retention mechanism is fully engaged. Verify stability before wearing the watch.

Yes, any aftermarket strap measuring 16 millimeters in width can be fitted to the Constellation 131.55.25.60.55.002, provided the lugs are compatible with standard springbars. However, to preserve the aesthetic and constructive identity of the watch, we recommend choosing high-quality straps made from noble leather materials (alligator, calf, shell cordovan) that respect the refinement of the yellow gold and Omega's design.

The lifespan of a leather strap depends on usage, maintenance, and the type of tanning. A vegetable-tanned calf strap, subject to moderate daily wear, lasts 2-4 years before requiring replacement; alligator and shell cordovan, being more resistant, can reach 4-6 years. Critical factors are water exposure (which accelerates deterioration), perspiration, direct sunlight, and frequency of use. Regular maintenance (gentle cleaning, annual conditioning) significantly extends the strap's lifespan.
