Wow......They look great. Keeping my fingers crossed for the Zodiac 😁
Ya, me too. I won’t be able to go back for a week, cleaning out my in laws attic...lots of cool old things to find in boxes upon boxes of stuff. Father in law passed away, he was Japanese and saved/hoarded everything.
My condolences.
That first Seiko is some chunky-funky two-tone goodness. It's C-licious!
They sure are pretty. Are you going to keep them or part with them? They look completely unworn
Most watches will work, even if the oil is totally dry. It is not a good idea, if you want them to last. Hard to get parts for the old Seikos.
First rule of collecting old things, of any kind: condition, condition, condition.
I have to respectfully disagree on the parts issue. The OP's 7006 watch has the movement that is essentially the same as the 7009, and the modern 7sXX series. Parts are available. The 6619 is a little harder but was produced in many variants. What is difficult to find is the technical info on cross referencing which parts fit which movements.
Almost all the Seiko calibre's were produced in sufficient numbers that donor movements can be sourced easily and cheaply, and there are sources for NOS parts as well.
