@Josiebjudd Many things have appeared on the dial of an Omega Speedmaster, from cartoon dogs to mission crests to the god Apollo and Buzz Aldrinâs⦠rear end. But one design that rarely makes it is the moon itself, other than on the 2004 âMoon To Marsâ edition. Of course, this is easily remedied with a moonphase complication and while I concede that this is hardly a technical requirement for a tool watch, there is a certain charm to watching the progress of the moon across the dial of a Speedy. Running parallel to the classic Speedmaster Professional series were a range of Speedies referred to as the âMarkâ series. Starting at Mark II in 1969, implying that the original Moonwatch was Mark I, these were considered as potential replacements but ended up as variations on a theme. Their history is a little convoluted. The Mark II and Mark IV were all considered âProfessionalsâ despite not being âflight qualifiedâ by Nasa, while some Mark IIIs are labelled as âProfessionalâ depending on the variant and year of production.Â
