The OMEGA Speedmaster sapphire represents horological excellence with its robust 42mm stainless steel case and dual sapphire crystal construction—a domed front with anti-reflective coating for optimal legibility and a transparent caseback revealing the mechanical heart within. The anodised aluminium bezel ring ensures durability without compromising aesthetics. At its core beats the Calibre Omega 3861, a manual-winding chronometer movement equipped with chronograph functionality and small seconds subdial, delivering approximately 50 hours of power reserve. The striking black step dial provides refined contrast and precision timekeeping. A timepiece engineered for those who demand both technical sophistication and enduring craftsmanship.
