Omega
Constellation 1566.76.00

For the 1566.76.00 we primarily recommend black or medium brown alligator, which respects the understated elegance of the model and its Seventies heritage. Alternatively, vegetable-tanned calf for those who desire a patina that develops over time, or burgundy shell cordovan for warm luminosity. For versatile daily use, a vulcanized rubber strap or a linen NATO maintain the formal balance of the Constellation.

The strap on the Omega Constellation 1566.76.00 is changed by removing the spring bars from the case. Use a specific tool (spring bar tool) to gently push the small lateral pin of the spring bar inward, thereby freeing the strap from the case lugs. Insert the holes of the new strap onto the spring bars and use the tool again to reposition them in their seats. Never force: the movement must be smooth and controlled to avoid scratches.

The lifespan of a leather strap depends on daily use and the material chosen. Alligator and vegetable-tanned calf have a life of 3-5 years under normal use conditions, especially if exposed to humidity. Shell cordovan, thanks to its natural rigidity and superior density, can last 5-7 years. Proper maintenance — avoiding prolonged water exposure and occasionally conditioning the leather — significantly extends longevity. Casati Milano warrants every strap for 18 months.
