Omega introduced the Speedmaster Alaska in 2008 when this watch was bought as well. It has such a strong bright white dial, much whiter than the popular and rare 35th anniversary Speedmaster which has a more silverish dial. While the 35th anniversary Speedmaster is limited to 3500 pieces, the Alaska is much rarer and limited to only 1970 pieces.
I guess the limitation of 1970 pieces is a reminder that Omega built the red exterior case for their “Alaska Project” watch in the early 1970s prototype which was auctioned off at the Omegamania auction by Antiquorum in 2007. You can find a PDF file with the auction on the Chronomaddox site.
I tried to capture the dial with some macroshots.
The goal of the creation of this project was to built a watch that is suited for extremely low temperatures.
That is why Omega built the extra large red case which can house this watch.
This watch has a 42mm large contemporary case.
There are two contributions on the web which talk about the history of this watch in detail.
