Omega Speedmaster Professional Moonwatch

Qualified by NASA for manned spaceflight in 1965 and worn on the lunar surface four years later, the Speedmaster Professional is the most historically significant chronograph ever made. This 42mm steel reference keeps the asymmetric case, black tachymeter bezel and three-register dial that earned that status, and adds a sapphire caseback so the hand-wound Co-Axial Master Chronometer Calibre 3861 can be seen at work — METAS-certified and resistant to 15,000 gauss.
