This Omega Speedmaster Professional Moonwatch reference 310.23.42.50.99.001 brings the classic 42mm Moonwatch profile into a more elevated, two-tone configuration. A sun-brushed 18K Sedna™ gold dial, black chronograph registers, black ceramic tachymeter bezel with Sedna™ gold ring, and black leather strap create a warm yet restrained interpretation of the Speedmaster. Offered pre-owned in excellent overall condition with original box, full card set, manuals, and warranty card dated April 6, 2025.

Dial: Sun-brushed 18K Sedna™ gold dial with black chronograph subdials, applied hour markers, luminous hands and indices, and a classic three-register layout. The black ceramic bezel frames the dial with a high-contrast tachymeter scale, while the lume photographs show clear, even illumination.
