Omega Speedmaster Professional
Almost 50 years ago, Buzz Aldrin walked on the moon wearing an Omega Speedmaster Professional which in turn now has the nickname "Moonwatch" for obvious reasons. This timepiece holds an important place in space history as it is the only piece of equipment to have been used in ALL of NASA's missions starting from Gemini.
This beautiful 2005 chronograph has a 48 hour power reserve, 42mm case, and 18 jewels. Very minimal wear leaves this piece looking stunning as ever. The hour and minute hands are coated in Super-LumiNova making it extremely visible in the dark.
Movement caliber 1861
