Strap for Constellation Quartz 24 Brushed Stainless Steel / Red Gold / MOP

The lug width of the Constellation 123.20.24.60.55.001 is 16 mm. This dimension refers to the distance between the internal suspension lugs and is critical to ensure a perfect fit for any aftermarket strap. Always verify that the strap is exactly 16 mm before installation.

For this compact model in rose gold and steel with mother-of-pearl dial, we recommend black or dark brown Nile alligator for classic elegance, or French vegetable-tanned calf for a more contemporary profile. Silk or cotton NATO straps represent an informal alternative that does not compromise the case aesthetics. The choice depends on the intended use: daily wear, formal, or sporty.

The Constellation uses standard spring bars. Obtain a spring bar removal tool or consult a watchmaker. Press the small lateral button of the spring bar downward, remove the pin, then remove the old strap and insert the new one by aligning the holes. Ensure the spring bar is fully engaged before wearing the watch.

Yes, any strap with a 16 mm lug width is compatible with the Constellation 123.20.24.60.55.001. Custom handcrafted straps from milanostraps are customizable and guarantee correct dimensional tolerance. For a bespoke result, the Casati Milano atelier offers made-to-measure creation with direct selection of leathers and rose gold finishes if desired.

A superior quality alligator or calf strap lasts on average 2-4 years with daily use, with the possibility of extending up to 5-6 years by alternating with other straps. Durability depends on humidity exposure, body perspiration, and periodic maintenance (gentle cleaning and conditioning). Handcrafted straps from Casati Milano include an 18-month warranty and can be restored after initial wear.
