Strap for Constellation Quartz 27 Brushed Yellow Gold / Diamond / MOP

The lug width of the Constellation 123.55.27.60.55.004 is exactly 20mm. This measurement is critical when purchasing compatible straps. To verify, measure the distance between the two metal lugs on the case using a digital caliper, positioning it perpendicular to the dial.

Alligator is the ideal material for this model. Its natural geometric texture and the way it develops patina over time create visual harmony with yellow gold. Alternatively, English calf leather in chocolate or tobacco tones offers comparable elegance with superior softness to the touch.

To change the strap, you will need a spring bar tool. Place the watch on a stable surface, locate the metal lugs at the case attachments, gently push inward with the tool to release the internal spring, then slide the old strap outward. Repeat the procedure with the new strap. If you are unsure, consult a professional.

Yes, it is possible. It is essential to verify that the strap is sized exactly 20mm in lug width. On milanostraps.it you will find a wide selection of straps in alligator, calf and rubber, all compatible with this lug width and customizable according to your color and stitching preferences.

Durability depends on leather quality and conditions of use. An artisanal alligator or calf leather strap, subject to regular maintenance (cleaning with a damp cloth, natural drying, occasional application of protective balm), typically lasts 5-8 years before replacement is needed. Artisanal straps from Casati Milano include an 18-month warranty and support for extending durability through targeted regeneration.
