Strap for Constellation Quadrella Quartz 25 Stainless Steel / MOP

The lug width of the Constellation 1585.79.00 is 19mm. This measurement is determined by the distance between the two spring bars that attach the strap to the case lugs. It is essential to measure this dimension accurately before ordering an aftermarket strap to ensure proper fit and aesthetic balance of the watch.

The ideal strap depends on personal style and the watch dial. For a classic approach, black or dark brown alligator is the most versatile choice. For those seeking a patina that evolves over time, vegetable-tanned calf leather in bordeaux or cognac tones is excellent. Shell cordovan represents the perfect compromise between elegance and durability. Rubber models are recommended for more sporty and contemporary use.

The replacement is relatively straightforward. Position the watch on a soft cloth with the dial facing down. Locate the spring bars that attach the strap to the lugs (one on each side). Use a spring bar removal tool or a small pry bar to gently extract the spring bar, replacing the old strap with the new one. If unsure, consult a professional watchmaker or our atelier.

The lifespan of a leather strap depends on the quality of the material, frequency of use, and care. A quality alligator strap with vegetable tanning typically lasts 3-5 years of daily wear before replacement is needed. Shell cordovan is even more durable (5-7 years), while standard calf leather lasts 2-3 years. Protecting the strap from excessive moisture, prolonged sun exposure, and external dirt will significantly extend its lifespan.
