Strap for Constellation Co-Axial 35 Stainless Steel / Yellow Gold / Diamond / Silver

The lug width of the Constellation 123.25.35.20.52.002 is 20mm. This measurement refers to the inner distance between the case lugs and is the correct strap size you need to install. Always verify this measurement before purchase to ensure absolute compatibility.

For the Constellation in yellow gold and steel, we recommend straps in dark brown alligator, vegetable tanned chestnut calf, or shell cordovan. These materials create tonal harmony with the gold and maintain the discreet elegance of the model. Avoid synthetic materials that contrast excessively with the watch's construction quality.

The strap is changed by removing the spring bars that secure it to the case lugs. Using a spring bar tool, slide the pin inward until it releases from the lug. Insert the new strap and reinsert the spring bar until it clicks into place. If you are not confident, entrust the task to a trusted watchmaker.

Yes, the Constellation 123.25.35.20.52.002 accepts aftermarket straps of 20mm artisanal quality. Consult our catalog of straps compatible with 20mm lug width on milanostraps.it, where you will find options in vegetable leather, alligator, and other materials, customizable according to your preferences.

An artisanal vegetable tanned leather strap of good quality lasts on average 3-5 years with daily wear, depending on climate, humidity, and leather type. Alligator and shell cordovan age more slowly, developing patina. Our Casati Milano straps include an 18-month warranty and can be refurbished upon request.
