Strap for Constellation Quartz 27 Brushed Stainless Steel / Diamond / MOP

The lug width of the Constellation 123.15.27.60.05.001 is 18mm. This dimension is specific to the 27mm model and is determined by the internal distance between the two integrated lugs on the case. Only straps with an 18mm attachment will mount correctly, without forcing or risk of damaging the original Omega springbars.

Alligator is the most coherent choice with the model's aesthetic identity, thanks to its natural grain that proportions perfectly to the compact diameter. Alternatively, vegetable-tanned calf offers evolutionary character and a patina that develops over the years, while technical rubber represents the modern option for those prioritizing comfort and moisture resilience.

Strap replacement requires extraction of the springbar that connects the two lugs. Using a dedicated tool (springbar tool), slightly compress the spring to extract it from the holes at the lug ends, then slide off the old strap and position the new one. The procedure is reversible and does not damage the watch if performed with care.

Yes, provided it has an 18mm lug width. Quality aftermarket straps (such as those by Milano Straps) are engineered to fit watches with specific dimensions and guarantee complete compatibility. We recommend avoiding generic straps from uncertain sources, which could compromise the integrity of the original lug.

Durability depends on the tanning method and usage: quality alligator or calf offers 3 to 7 years of daily wear before requiring replacement. Vegetable tanning tends to age more gracefully, developing patina, while technical rubber can last 5-10 years under normal conditions. Maintenance (avoiding excessive moisture, preventing aggressive cleaners) significantly extends the strap's lifespan.
