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

The lug width of the Constellation 131.20.25.60.05.002 is exactly 16mm. This measurement represents the distance between the two lugs that secure the strap to the case. It is essential to verify this dimension before purchasing an aftermarket strap to ensure perfect compatibility and correct visual appearance.

Alligator is the most elegant and classic choice for this model, as its regular grain enhances the sophistication of the mother-of-pearl dial. Valid alternatives include vegetable-tanned calf for a natural patina that develops over time, shell cordovan for extraordinary durability, or a cotton NATO for a casual approach. The choice depends on your personal style and frequency of use.

The strap is changed by removing the lateral pins (or the retaining spring, if present) that secure the strap to the case. You can do this with a spring bar tool or dedicated tool, creating thin levers on the sides of the case. Remove the old strap, insert the new one by aligning it with the 16mm lugs, and reinsert the pins until you feel a click indicating correct fastening. If you are not experienced, it is advisable to consult a watchmaker or the Casati Milano atelier to avoid damage.

The original Manhattan bracelet is integrated into the case by Omega and is part of the designed structure. Aftermarket straps, while having the same lug width (16mm), offer aesthetic and practical flexibility: change material, color, and texture according to the seasons or your mood. Straps in alligator, vegetable-tanned calf, or shell cordovan age naturally and develop a unique patina, unlike the Manhattan metal bracelet which maintains a more static brilliance.

The durability of a leather strap depends on the material and usage. A vegetable-tanned calf lasts on average 3-5 years with daily wear; alligator, being more resistant, reaches 5-7 years; shell cordovan is the most durable and can exceed 10 years. Factors such as humidity, sun exposure, and frequency of use influence aging. The Casati Milano atelier offers an 18-month warranty on its straps and can replace only the leather while maintaining the original craftsmanship.
