The Speedmaster was originally introduced in 1957 as a racing watch, and it wasn't until 1969 – when the hand-wound chronograph accompanied the crew of Apollo 11 onto the surface of the Moon – that it received the legendary status it currently holds. Today, the Speedmaster collection is an expansive series of chronographs that includes models geared toward space exploration, racing, heritage, and modern technological advancement among much else. Historically, it's one of the most iconic watch lines of all time, and continues to serve as one of the most signficant design families of watches ever developed.
