Speedmaster with 220 bezel

Hi!

I'm new to the forum so maybe (certainly) there's som discussion about the history of the 220 bezel somewhere?

If not, I really would like to know more about it. This is what I "know".
• A misprint in -69
• produced for about 7 weeks...
• ...within the Alaska Project.

Hi and welcome to the forum

I have one of this Speedmaster's and there is a lot of information regarding this topic in the vintage section of this forum.

As fare as i know this watches can not be related to the Alaska project and my Speedmaster all original was produced 29 of September 1970 even if the ref is 145.022-69.
What's important here is the serialnumber of the movment as it should be within 30 to the 31 range ( Very roughly ).

Happy reading 😀
