About this watch

The Omega Constellation Co-Axial 31 is a stunning blend of sophistication and mechanical excellence, featuring a unique combination of red gold and stainless steel that creates a striking contrast. The rich brown dial adds warmth to any outfit, while the round case (31mm diameter) sits comfortably on the wrist.
