Strap for Constellation Quartz 24 Polished Stainless Steel / Red Gold / Diamond / MOP Supernova

The lug width (misura ansa) of the Constellation 123.25.24.60.55.006 is 16 millimetres. This measurement refers to the internal distance between the two lugs protruding from the case. It is critical to verify this dimension accurately before purchasing an aftermarket strap, as even minor discrepancies (15 or 17 mm) would compromise the fit and security of wear.

For this model, we primarily recommend alligator leather in black or brown, which balances elegance with durability. Shell cordovan remains an excellent alternative thanks to its natural patina and compatibility with rose gold warmth. Vegetable-tanned calf leather in black or burgundy represents a versatile choice for daily wear. For more casual contexts, a NATO strap in technical fabric offers practicality without compromising the watch's character.

Given the presence of the iconic griffes (claws on the case), strap replacement requires caution. Precision spring bar tools are necessary, and work must be conducted in very tight spaces. We strongly recommend entrusting this operation to a professional or contacting Casati Milano: the atelier offers personalised installation service with a guarantee on the workmanship.

Yes, provided the lug width is exactly 16 mm. However, due to the particular case shape with griffes, it is necessary to select a strap with lugs (passants) that are appropriately shaped. Milano Straps supplies straps specifically designed for this geometry, with customisation options in size and material. The Casati Milano atelier is available for technical consultations and bespoke creations.

A high-quality leather strap, subject to vegetable tanning and artisanal construction, has a lifespan of 3-5 years with daily use and regular maintenance. Alligator and shell cordovan, thanks to their natural density, tend towards the upper range. Longevity depends on frequency of use, ambient humidity and periodic cleaning. Milano Straps offers an 18-month guarantee and continuous maintenance support.
