Here is my blue dial 6009 perhaps from the last month as you've mentioned. Yellow dial 6009 seems uncommon and unlikely to be that way from factory.All 69' 6139-6009's are Resist models and have notched cases. The notched case Resist 6009's models ran up to July of 70' and had 2 piece sweep hands with an "A" movement. The case back on the 6009's is also different from any other 6139-600X showing only "Water Resist" rather then "Water Resistant". I've seen them as early as July 69' but have never seen a Yellow dial notched case 6009 Resist model so I'd have to question the one shown but, as we all know, anything is possible.
