Strap for Constellation Quartz 27 Brushed Yellow Gold / Champagne Supernova

The lug width of this model is 20mm. This dimension corresponds to the distance between the lateral spring bar attachments on the case. It is essential to measure this parameter correctly before ordering a replacement strap, as it determines complete compatibility with the case.

For this 27mm yellow gold case, we recommend dark brown alligator (Cognac) or vegetable-tanned calf leather in Bordeaux. Alligator offers a natural texture and ages magnificently, while vegetable-tanned calf ensures environmental responsibility and extraordinary color depth after months of use. Both materials enhance the golden luminosity of the case.

To change the strap, you need to remove the spring bars positioned laterally on the case using a dedicated tool (spring bar tool). Position the tool in the small notches, apply gentle pressure to compress the spring, then extract the attachment. Repeat the operation on both sides and install the new strap following the reverse procedure. We recommend seeking assistance from a professional if you are uncertain.

Any strap with a 20mm lug width is compatible. You can choose from alligator, natural calf, shell cordovan, synthetic rubber, NATO fabric, or other materials, provided they respect this dimension. On MilanoStraps you will find a curated selection of 20mm compatible straps, customizable with initials and stitching thread choice.

A premium artisanal quality leather strap has an average lifespan of 3-5 years with daily use, varying based on climatic conditions and frequency of use. Alligator and shell cordovan tend to last longer thanks to their dense fibrous structure. Straps crafted by Casati Milano benefit from an 18-month warranty and can be renewed through a maintenance service.
