Finding a birth year speedmaste is a challenge.
What do you mean by birth year?
Year of movement/case ref? (Though ref on a '82 is not applicable)
Year of release by omega as shown on an extract?
Year of sale as shown in first sale receipt ?
So in fact this could mean the net could be cast wider.
Good luck in your search!
Circa 1982 Speedmasters are great vlue.
