Hi All. Recently acquired this speedmaster and am about to sink in approx $500 to have it serviced. Am I correct in identifying it as a 1970 model? With the case cleaned and movement fully restored with a replacement strap (possibly HIRSCH for the time being - thanks for the advice from the members in my last post) what would be a modest price to insure this piece at? Perspex glass has original omega embossing in middle. Will provide any more info. Would love to know as much about this model as possible.
Congratulations. You do have a special model. Look at the bezel. It is a misprint 220 bezel wich is quite cool. Movement number looks perfectly fine for these models wich were produced only in fall 1970 (between 30.589.xxx and 31.000 according to moonwachonly). Dial, lume, handset, casebook look also good (but quite worn).
The 220 bezels were produced mainly in the 3rd quarter of 1970 (some in the 4th quarter) so there you have a nice narrow time frame
