The Omega Speedmaster Professional is one of the world's most iconic watches - and for very good reason, as it is the only watch to be flight-qualified by NASA.
This means it has accompanied astronauts on countless space flights over the years, travelled to the Moon on the wrists of Neil Armstrong and Buzz Aldrin, and was even used to help the crew of the stricken Apollo 13 return to Earth.
Aside from the Nasa stamp of authority, which sits in the case back of all Speedmaster Professionals, the watch is a quality timepiece, with chronograph complication and a tachymetre bezel for measuring the average speed of an object over a known distance.
Highlighted below are three versions of Omega Speedmaster current on sale at Goldsmiths. These include a £470 saving on a model with a sapphire case back, £395 off the steel-backed model with black leather strap, and £400 off the Speedmaster with steel back and matching strap.
