Strap for Constellation Quartz 27 Polished Stainless Steel / Yellow Gold / MOP

The lug width is 18mm. This measurement represents the distance between the two lateral shoulders of the case where the watch strap lugs are seated. Always verify this dimension with a caliper before ordering a replacement strap, as it is not compatible with other measurements.

A cognac vegetable-tanned alligator or dark brown brushed calf are the most refined choices, as they balance the gold/steel contrast without competing with the mother-of-pearl. For more sporty use, burgundy shell cordovan offers a rich patina over time, while a navy silicone rubber strap may be appropriate for nautical contexts.

The lug width is measured by positioning a digital caliper across the lateral shoulders of the case and recording the distance between the two contact points. Do not confuse lug width with the thickness of the strap leather: lug width is a fixed geometric dimension of the case, whereas the strap is an independent element that seats within it via its lugs.

Any handcrafted strap with 18mm lug width is compatible with this model. On milanostraps.it you will find a specific collection of 18mm straps customizable in sizes, colors and finishes, as well as the option to request bespoke pieces through the Casati Milano atelier.
