Strap for Constellation Quartz 27 Polished Stainless Steel / Yellow Gold / Diamond / MOP

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of this model is 16mm. This specific width characterizes the Constellation ladies' models of this generation and it is essential to verify it before ordering an aftermarket strap to ensure perfect compatibility with the case lugs.

For this Constellation we recommend straps in <a href="/pages/termine-glossario/alligatore">alligator</a> or calf leather with polished finish, which enhance the refinement of the mother-of-pearl dial. <a href="/pages/termine-glossario/alligatore">Alligator</a> with irregular grain imparts a sartorial elegance, while vegetable-tanned calf offers a patina that ages nobly. Avoid NATO, too casual for this reference.

Unlike models with detachable lugs, the Constellation 123.25.27.60.55.007 requires a more delicate strap change. The strap does not attach via traditional spring bars but through a mechanism integrated into the case. We recommend contacting a specialized workshop or Atelier Casati Milano to perform the replacement without compromising the integrity of the case.

An aftermarket strap in <a href="/pages/termine-glossario/misura-ansa">16mm lug width</a> is compatible only if the strap has been specifically designed for the integrated attachment system of this case. Not all 16mm straps adapt to the Constellation architecture. Contacting Casati Milano ensures precise and reversible fitting.

A high-quality <a href="/pages/termine-glossario/concia-vegetale">vegetable-tanned</a> strap, such as those offered by Milano Straps, lasts an average of 3-5 years with daily use and proper maintenance. Exposure to sun, chlorine and humidity accelerates aging. Casati Milano's 18-month warranty covers manufacturing defects; periodic replacement remains an aesthetic and comfort choice.
