A high-precision chronograph timepiece featuring Omega’s iconic Speedmaster Professional design, famously worn during NASA moon missions. This model showcases a deep blue sunburst dial with three subdials (30-min, 12-hr, and small seconds), white applied hour markers, and luminous hands for optimal legibility. The fixed blue ceramic bezel is engraved with a tachymeter scale (60–500 units), complementing the polished stainless steel case (42mm) and integrated bracelet with brushed center links and polished edges. Powered by Omega’s Co-Axial Master Chronometer movement (Calibre 3861), it offers certified chronometric precision, magnetic resistance up to 15,000 gauss, and 100m water resistance. The sapphire crystal with anti-reflective treatment ensures clarity, while the screw-down crown and pushers secure chronograph functionality. Ideal for enthusiasts seeking heritage engineering with modern reliability—perfect for daily wear, business-casual settings, or as a statement piece for collectors. Its balanced proportions, robust build, and timeless racing-inspired aesthetic make it equally suited for formal events or weekend adventures.
