Strap for Constellation Quadrella Quartz 25 Stainless Steel / MOP / White Alligator

The lug width of the 1886.79.36 is 18mm, measured internally between the two metal pins. This dimension is specific to this model and is not interchangeable with straps of other sizes. To verify it, use a digital caliper or contact the seller directly.

For the Constellation 1886.79.36 we recommend satin alligator in black or dark brown for formal elegance, or shell cordovan for those who desire a patina that evolves over time. Vegetable-tanned calf leather is ideal for refined daily wear. The choice depends on personal style and occasion.

Strap replacement requires the use of a dedicated tool (spring bar tool). Gently remove the metal pins that secure the original bracelet or strap, then insert the new 18mm strap ensuring that the pins click firmly into the lugs. If you are not experienced, consult a certified watchmaker.

Durability depends on the material and usage. Quality alligator lasts 3-5 years with moderate daily wear. Shell cordovan can exceed 10 years and improves with age. Vegetable-tanned calf, being softer, has an average lifespan of 2-4 years. Factors such as humidity, perspiration, and frequency of wear significantly influence longevity.
