    My guess, 1959 - 60.

    The movement would still have been a relatively recent introduction for this interval.

    The 10.5''' version (P62) was available at least as early as 1957.

    1971 ad

    Waltham had changed to block lettering for the name and no logo. 1960's you had the red W. By the 70's they were not trying too hard. Check out the marker and hand styles. The case style on the automatic Admiral or the Sea Chase.

    Edit.....I do admit they used the big black W made up of chevrons in the 70's too but not the red W.

    I also believe it is from the 1970's or early 1980's

    It seems to have the case style of the 1970's into the early 1980's. I have several Seiko watches with that type of case

    Here is one of my 1960's Waltham 100 Jewel watches of the mid 1960's (17j that actually do something and 83 that just hang out.

    I believe they used there are other jewels used in the self winding part of those and the extra were used to "help reduce friction" for the under side of the rotor as it travels around the outside of the movement. Honestly the rotor never touches that part so.....yeah.


    Pictures help...
