Strap for Constellation Quartz 27 Brushed Stainless Steel / Diamond / Black Supernova

The lug width of model 123.15.27.60.51.001 is exactly 16mm. This width is specific to the 27mm case and is essential to ensure complete compatibility with any aftermarket strap. Verifying it with a caliper before ordering is recommended practice.

Brown cognac alligator represents the most refined and harmonious choice: the natural texture dialogues perfectly with the brushed steel case. Alternatively, burgundy shell cordovan offers deep patina and visible artisanal construction over time, while vegetable-tanned calf leather guarantees extended comfort without initial stiffness.

Position the watch on a soft cushion with the lugs facing upward. Use a springbar tool to gently depress the inner spring of each attachment, sliding the old strap outward. Insert the new strap by aligning the eyes with the attachments, then repeat in reverse ensuring the final click of the spring.

Yes, all 16mm Milano Straps straps are fully compatible with this model. Always verify that the lug width ordered corresponds to 16mm: we communicate precise dimensions accurately, but your confirmation is a guarantee of perfect fit.

A quality leather strap (alligator, cordovan, calf) typically lasts 3-5 years with daily wear, depending on sun exposure, humidity, and maintenance. The leather naturally softens, developing unique patina. Milano Straps offers an 18-month warranty on all straps, and springbar replacement is a simple and economical operation even after expiration.
