OMEGA Speedmaster Moonwatch Brown Dial Watch 311.30.42.30.13.001

The OMEGA Speedmaster Moonwatch Brown Dial (Ref. 311.30.42.30.13.001) maintains every technical specification that earned NASA qualification for all manned space missions whilst offering sophisticated brown dial alternative to the traditional black Moonwatch. This represents the only watch worn on the Moon’s surface during all six Apollo lunar landings, with heritage earned through actual space exploration rather than marketing claims.

At 42mm with 13.45mm thickness, this provides the classic Moonwatch proportions that proved optimal for space missions whilst accommodating the manual-winding movement without excessive bulk. The brown dial creates vintage-inspired warmth whilst maintaining the exact subdial configuration and marker design that proved essential during Apollo missions.

The manual-winding Calibre 1863 descends directly from the movement that accompanied Neil Armstrong and Buzz Aldrin to the lunar surface. The 48-hour power reserve and column wheel chronograph construction provide the reliability that proved life-saving during Apollo 13 when astronauts used their Speedmaster to time the crucial engine burn that returned them safely to Earth.

The NASA qualification required functionality across extreme temperature ranges, vacuum conditions, shock, and radiation that far exceed terrestrial conditions. This testing established reliability standards that ensure exceptional everyday performance whilst validating capabilities under conditions that would disable lesser chronographs.

This Speedmaster Brown Dial suits buyers who want authentic space exploration heritage with distinctive aesthetic character. The brown colour provides sophisticated alternative whilst preserving the exact specifications that enabled space qualification, making this ideal for collectors seeking Moonwatch authenticity with unique visual appeal that honours humanity’s greatest exploration achievement.
