This vintage, steel Omega Speedmaster Ed White 105.003-65 . The watch?was purchased in May 1967 and comes complete with its inner and outer boxes and signed warranty card. It also retains its 1035-1501?flat-link bracelet and matching 6 end-links.

Colloquially referred to as the 'Ed White' Speedmaster, the watch was worn by NASA?astronaut Edward White, when he became the first American to perform a spacewalk.

The case

Sized at 40mm, the pre-professional Speedmasters such as this Ed White are most easily differentiated by the straight lug cases used and absence of crown guards, compared to the later, twisted bombe lugs. The case is in good vintage condition, with the correct crown attached. The caseback retains?a deep Omega hippocampus and is engraved on the inside 105.003-65 - also housing the original dust-cover. Further to this, the watch features a slightly ghosted,?Dot over 90 tachymeter bezel.

The dial

This pre-professional?Speedmaster has its original, stepped dial and features an applied Omega logo. The tritium hour markers have developed a dark-yellow patina, matching the handset. The tritium hands and hour markers themselves show all the signs of ageing, and retain?signs of luminescence under UV.

The movement

Powered by the famous calibre 321, it is a column-wheel chronograph movement that is heralded to be one of the greatest ever produced. All pre-professional Speedmasters utilised this high-end calibre, before Omega eventually switched to the more economical, non-column wheel Cal. 861.

Viewings can be arranged in Central London by appointment.
