Strap for Constellation Quartz 24 Polished Stainless Steel / Diamond / MOP

The lug width is 20mm. This measurement represents the external distance between the two pins that anchor the strap to the case. To verify it correctly, use a digital caliper by positioning the tips perpendicular to the pins. An error in measurement results in incompatible straps and mechanical stress on the case.

For maximum elegance, we recommend alligator in cognac brown or black with a deployant clasp. If you prefer versatility, vegetable-tanned calf leather (cognac or black) guarantees a patina that evolves over time, creating an aesthetic symbiosis with the steel case. For everyday or sports use, a grey-beige canvas NATO strap maintains the sporty character of the model.

To change the strap, obtain a dedicated tool (springbar tool) and a soft surface to rest the watch on. Position the tool in the small hole of the spring that supports the pin, pressing gently until the pin is released. Once the pin is removed, the strap slides off. Reinsert the pin into the new strap by aligning the holes and pressing until the locking click is heard. Avoid forcing: the movement should be fluid.

Yes, any strap with a 20mm lug width is compatible from a mechanical standpoint. However, Milano Straps recommends choosing quality artisanal straps: the visual proportions between case diameter (24mm), lug width (20mm), and strap thickness must be harmonious. Poor-quality straps compromise the elegance of the watch.

A quality alligator or calf strap, with vegetable tanning and artisanal craftsmanship, typically lasts 3-5 years of daily use. Durability depends on sun exposure, sweat, and humidity. The Casati Milano atelier provides an 18-month warranty and recommends regular maintenance: keep the leather dry, apply specific balms every 6 months, and rest the strap on alternating days to allow the fibers to breathe.
