Strap for Constellation Quartz 24 Polished Stainless Steel / Yellow Gold / Diamond / Champagne Supernova

The lug width of the Constellation 123.25.24.60.58.002 is 20mm. This measurement is determined by the architecture of the model's characteristic claws and represents the internal distance between the two metal pins that protrude from the case. To verify it, use a digital caliper inserted perpendicularly between the pins: the correct reading guarantees total compatibility of the replacement strap.

Vegetable-tanned alligator represents the ideal choice for this two-tone model, as the natural patina it develops amplifies the sophistication of the yellow gold and steel combination. Bordeaux shell cordovan and premium calf leather (taurillon or Saint-Barth) are excellent alternatives for formal occasions. For daily use, NATO fabrics maintain legibility without compromising the refined identity of the watch.

The Constellation 123.25.24.60.58.002 features straight shoulder pins that insert laterally into the case claws. Use a specific watchmaking tool: insert the pin from the opposite side of the attachment, applying steady pressure until it is completely removed. Replace the strap by inserting the new one from the opposite sides and pressing until the stopping point. We recommend having this operation performed by a goldsmith or authorized retailer to avoid damage to the case.

Yes, any strap with a 20mm lug width is technically compatible. However, to maintain the aesthetic integrity of the Constellation, we recommend straps made from noble leathers with hand-finished details. Milano Straps' 20mm straps are custom-made and customizable, ensuring constructive compatibility and artisanal quality aligned with the model's prestige.

Durability depends on usage intensity, climatic conditions, and leather quality. Premium alligator or calf with vegetable tanning maintains structural and aesthetic integrity for 3-5 years with regular use and proper maintenance. Protect the strap from prolonged moisture, direct sun exposure, and excessive perspiration. Periodic cleaning with a soft damp cloth and occasional application of a specific conditioner extend its useful life. The Casati Milano atelier offers an 18-month warranty on all custom-made straps.
