One of the fun things about Speedy Tuesday is that there are so many models and references, we will probably never run out of material to cover. We started on May 29th 2012, almost four years ago, and it doesnt take much time to think of a new subject to cover each single week. If there isnt a new Speedmaster to talk about, we try to answer a Speedmaster related question from one of our readers or focus on something vintage or special. I also believe that the Speedmaster is one of the few watches around that makes it possible to give it weekly coverage, for almost four years now.A few weeks ago, Bert and I visited the Davidoff Brothers in Geneva to have a look at their extensive Speedmaster collection. Not only do these guys buy sell vintage Speedmaster watches to earn a living, they live and love them dearly. Even on 10past10, the website of vintage specialist Eric Ku the brothers admitted in an interview that they love vintage Speedmasters over .Vintage Speedmaster Racing 145.022-68One of the Speedmasters that they showed us was this vintage Omega Speedmaster Racing 145.022-68.According to the archives, this particular Speedmaster Racing 145.022-68 was delivered to the USA in 1969. Although there is no paper trace of this, it was later on bought on a US military base in Korea. A very similar Speedmaster Racing was auctioned at the Christies Speedmaster 50 Auction and fetched $32.500 USD.About the vintage Speedmaster RacingWhen Omega introduced the Speedmaster in 1957, with their CK2915 reference, it was meant to be a watch for sports people. In a couple of advertisements, Omega pictured the Speedmaster CK2915 on the wrist of a car driver for example. Little did they know then about the Speedmaster becoming the official watch for NASA astronauts almost a decade later.In the late 1960s, Omega introduced the Speedmaster Mark II Racing. Thats the one we all know and it was in the regular collection of Omega in the late 1960s and early 1970s.A bit more vague is the production of these Omega Speedmaster Racing 145.022-68 and similar models from those days. We know that there are roughly three different versions of the vintage Speedmaster with a racing dial:Black dial, red/white hour markers, metal applied |? logo (105.003, 145.012)Black dial, orange/white hour markers, white |? logo (145.012-67, 145.012-68)Grey dial, orange/white (separated) hour markers, orange |? logo (145.022)In this article I am talking about the latter one of course, with the grey dial and orange hands and orange / white separated hour markers. The older version also has orange/white hour markers but these are connected to each other.The case, movement etc are all similar to the regular production 145.022 models with black and white dial.
