Strap for Constellation Quartz 27 Brushed Stainless Steel / Yellow Gold / Silver

The Omega Constellation 123.20.27.60.02.002 has a lug width of 20mm. This measurement is determined by the proportion between the 27mm case and the integrated original bracelet. To verify the compatibility of an aftermarket strap, always measure the distance between the spring bar attachment points using a millimeter ruler, considering tolerances of ±0.5mm.

The choice depends on usage and personal aesthetics. For maximum refinement, vegetable-tanned alligator develops a natural patina that enhances the yellow gold case. Italian calf leather represents an excellent compromise between daily durability and discreet elegance. For a contemporary approach, high-density rubber in black or grey transforms the watch into a versatile instrument without compromising the sophistication of the two-tone case design.

Changing the strap on a Constellation requires specific hand tools (spring bar remover or small screwdriver). Identify the small passthrough holes on the spring bar and insert the tool to slide the bar horizontally, being careful not to scratch the two-tone case in gold and steel. For your safety, we recommend consulting an expert: Milano Straps and the Casati Milano atelier offer professional replacement service.

No. Although 20mm is a common lug width found on many watches, perfect compatibility depends on the specific case proportions, spring bar position, and the aesthetic of the Constellation two-tone design. Always consult your model reference before purchasing an aftermarket strap. Milano Straps 20mm straps are tested to work with your Constellation.

Durability depends on the material and usage. Vegetable-tanned alligator, with proper care (drying after rain, protection from direct sunlight), maintains structural integrity for 3-5 years before requiring replacement. Italian calf leather lasts 2-4 years with regular use. The warranty offered by Casati Milano is 18 months, protecting you from manufacturing defects. Patina is part of the design: it is not decay, it is evolution.
