Strap for Constellation Co-Axial 27 Brushed Stainless Steel / Wavy MOP

The Omega Constellation 123.10.27.20.55.002 is fitted with lugs measuring exactly 18mm in width. This size is specific to the compact proportions of the 27mm case and ensures harmonious wearability. Any replacement strap must respect this measurement to avoid lateral play or misalignment.

The best strap depends on usage: for daily elegance, alligator in vegetable tanning with cognac brown or black shell cordovan leather represents the finest choice. Vegetable-tanned calf offers superior versatility and value for money. Rubber or NATO straps, while compatible, contradict the sophisticated identity of this feminine model.

Strap change is straightforward: use a small tool (spring bar remover) to push out the metal pins that anchor the old strap to the 18mm lugs. Insert the new strap by aligning the holes to the lugs, then reinsert the pins until they click into place. If uncertain, entrust it to a professional: Casati Milano offers this service with warranty.

Yes, any quality strap with 18mm lug width is compatible with the Constellation 123.10.27.20.55.002. Milano Straps offers a selection of artisanal straps in alligator, calf, and shell cordovan, designed and tested for this specific measurement, with the option to customize length, color, and details.

Durability depends on material and usage: vegetable-tanned alligator averages 3-5 years with daily wear; shell cordovan reaches 7-10 years thanks to its more fibrous structure; vegetable-tanned calf approximately 4-6 years. A well-maintained strap, protected from excessive moisture and direct sunlight, maintains superior performance and aesthetics over time.
