Omega Speedmaster:
In 1957, Omega unveiled a chronograph that was a technological marvel, the Speedmaster. Its durability and accuracy would not only win it accolades around the world and the distinction of being the first watch to be worn on the moon, it would guide the crew of Apollo 13 safely back home after their malfunctioning electronic systems had shut down. The Speedmaster is one of the most prominent chronograph models in watch collecting.
