Strap for Constellation Quartz 24 Stainless Steel / Yellow Gold / MOP

The lug width of the Constellation 123.20.24.60.55.008 is 20mm. This dimension is specific to this compact 24mm diameter reference. Always measure the space between the two case lugs (excluding the height of the lug bars themselves) to verify the compatibility of any alternative strap.

We recommend alligator or crocodile for formal elegance, vegetable-tanned calfskin for comfort and patina over time, or canvas NATO for summer versatility. Cognac brown alligator is the natural pairing with the yellow gold case. Shell cordovan offers unique luster, although less common for compact models.

The strap is changed by removing the original integrated bracelet via screw attachments or spring bars (specific to the model). Insert the new 20mm strap into the case lug bars, ensuring it is centered and flush. If you are not experienced, entrust the task to a qualified watchmaker to avoid damage to the case.

Yes, all straps with 20mm lug width are compatible with the Constellation 123.20.24.60.55.008. Always verify the 20mm specification with the manufacturer. Milano Straps offers a wide selection of 20mm straps in leather and technical materials, customizable for size, initials, and stitching thread.

A quality leather strap (alligator, calfskin, shell cordovan) typically lasts 3–5 years with regular use, depending on exposure to moisture and perspiration. Vegetable-tanned leather ages gracefully, developing a characteristic patina. Straps made with premium materials maintain functionality and aesthetics longer than economical leathers.
