6139-600x Proof to Resist transition date by market
In which month did rest-of-world 6139-600x dials change from 'Water 70m Proof' to 'Water 70m Resist', and were North American dials genuinely 'Resist' from the outset?
Best current answer
Around mid-1970 for rest-of-world dials, with North American -6005 and -6009 examples reported as 'Resist' from 1969. Recorded as a production change at 'probable' confidence with the market qualification attached.
Conflicting claims
Dates in circulation come from observed watches rather than from Seiko documentation, and observed-watch dating is itself subject to the decade ambiguity in the serial. The reasoning is close to circular and should be treated with corresponding care.
Scope The dial/caseback wording agreement check on the 6139 family depends on this transition being placed correctly.
