Strap for Constellation Quartz 27.5 Stainless Steel / Yellow Gold / Silver

The Omega Constellation 1382.30.00 has a lug width of exactly 20 millimeters. This measurement represents the distance between the two case lugs and is essential for choosing a compatible strap. You can verify it by positioning a millimeter ruler perpendicular to the lugs, from inner point to inner point. No margin of error is tolerated: 20 mm guarantees perfect fit without play.

For the Constellation 1382.30.00 bi-metal (yellow gold + steel) we recommend dark brown or cognac alligator, which echoes the chromatic temperature of gold without competing visually. Vegetable-tanned calf in cordovan tone acquires a contemporary resonance while maintaining formality. For those desiring sportiness, a navy NATO or an FKM rubber strap delivers the original yacht-club atmosphere of the model from the 1980s.

The change requires the use of a specific tool (spring bar tool) to remove the suspension springs from the lugs. Position the watch in a soft-jaw vise, insert the flat screwdriver into the spring slot, lift gently until the spring snaps out. Repeat for the other end. For a professional result without risk of scratches on the gold case, we recommend entrusting the operation to an expert such as atelier Casati Milano.

The lifespan of a leather strap depends on frequency of use, material and climatic conditions. A quality alligator or calf with vegetable tanning maintains structural integrity for 4-6 years of daily use, while developing a natural patina that increases its character. Exposure to humidity, intense sunlight and perspiration accelerates aging. Atelier Casati Milano guarantees 18 months from creation, with the possibility of maintenance and stitching renewal.
