		As many of you know, I have struggled to find a way to clearly explain the relationship between various Omega Speedmaster product lines of the past and present. Frankly I'm not sure there is a clear way to do so. There are of course many possibilities: An evolutionary chart (like the history of the hominds), a family tree, a Venn Diagram, etc. It occured to me that perhaps a Timeline might make a decent metaphor for trying to explain the differing product lines and as a nexus of where to find more information about specific product lines and models.... I may in the future explore the other possibilities (family tree, Venn, etc.) but this is a first attempt (please be gentle!)...
		Key: Graphic: Definition: The main Speedmaster line, All Pre-Pro's and the main moonwatch line after Apollo 11. Including Moonwatch cased moonphase Speedys. The Speedmaster Mark Series The c.1045 (Lemania 5100) Speedmaster Automatic Day-Date line... Anniversary or Commemorative Speedmaster models. German Market or Teutonic Speedmasters.
		Caliber's in production...

1957													The initial model of Speedmaster was produced for parts of two years before being superceeded by the CK2998/105.002 model. Recently Omega has produced a "re-production" of this model with a modern twisted lug case, slightly different hands and the modern c.1861 movement.
1958
1959													There seems to be some confusion about the 105.002... I've talked to a number of people who believe that the 105.002, and who am I to disagree. It seems that the CK2998 model also is sometimes referred to as the 105.002 as well. Until I am able to learn more this note will have to suffice... This model is also known as the "Wally Schirra" as he was the first astronaut to wear the Speedmaster into Space.
1960
1961
1962
1963													The 105.003 is also known as the "Ed White" model because White wore one of these on his Spacewalk. This model was superseeded by the 105.012 (Pro) late in 1965.
1964
1965														The 105.012 is identical to the 145.012 but carried this model number for it's short (4-6 month) production run...
1966													A model Number change from the 105.012, the 145.012's production ran from early 1966 through the first half of October 1968 when the c.861 Based 145.022 replaced it.

1984													The Speedmaster Mark V is the single "Unifing watch" of three Speedmaster product lines: Mark Series,c.1045 Automatic Day-Date Series, and "Teutonic" German-Market Series. As such it is a very unique piece. The Speedmaster "Missing Link"...
