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

The Constellation 131.25.25.60.63.001 features a 16mm lug width. This specification is determined by the engineering of the 25mm case and the integrated geometry of the Manhattan bracelet. The tolerance is extremely tight to preserve the original aesthetic proportions. It is essential to measure correctly using a digital calliper, positioning it perpendicular to the lugs, measuring from outer edge to outer edge of the attachment space.

The choice depends on usage and aesthetic preference. Alligator represents the most aristocratic solution, enhancing the two-tone case and the mother-of-pearl dial. Vegetable-tanned calf offers daily versatility and develops a rich patina over time. Shell Cordovan, with its intense burgundy hue, represents a formal and refined choice. For a more casual approach, a taupe NATO or FKM rubber maintains elegance while offering practicality.

The spring bars on the 131.25.25.60.63.001 are easily removable with a standard spring bar tool. Insert the tool into the small lateral slot of the lug, apply gentle downward pressure to compress the internal spring, and the bar will slide out. Repeat on the opposite side. Insert the new strap by aligning the lug width with the case holes and reposition the spring bars into their seats. Proceed with caution: the case is precious and allows little margin for error.

A high-quality artisanal leather strap, worn daily, has an average lifespan of 3–5 years before replacement is required. Shell Cordovan and alligator are among the most durable materials, with a potential lifespan of 5–7 years. Vegetable-tanned calf, being softer, tends towards 3–4 years. Longevity depends on exposure to moisture, perspiration, direct sunlight and frequency of use. Regular maintenance with specific oils and proper storage in dry environments can significantly extend the strap's life.
