    Hello

    Can anyone point me to a good source (sources) of information about these? I have tried the usual Google searches and of this and other sites with little success. They seem to me to be nice watches and currently less loved than the 300s. As a new boy in this area I would welcome some help about where to go and what sort of ballpark I should expect to pay. Thank you

    I have one on order, should have it within a few days. I believe it is circa 1967 ish. I will post pics.

    I don't think there is a definitive site regarding these watches. Just various bit and pieces to pick up from here and there. One important point I learned is that there are 2 sizes from the late 60's. A men's 38mm and a Ladies 31mm. Even if the seller does not properly disclose, the difference is easily seen in the layout of the "T"s on the dial.

    I also believe that the normal version is a 24 jewel, automatic. There are some 17 jewel, hand wound versions as well. Omega imported these to the USA and saved import duties by using a movement of 17 jewels.

    Good hunting

    I have a 166.0027 which is the 565 auto. I think the manual is a 601 and usually sells for less. Good poi from Gemini about the ladies size as I think a few people have almost bought these in error. I think they have a 68x movement so, steer clear.

    Bezel is unobtainable and in my opinion its not possible to have it restored as it is a one piece machining. Dials are unobtainable as well, I believe but you might get hands.

    Prices are on the increase, unfortunately.

    Here's mine:

    I took a chance buying this. Have a look here:

    Yes, the bezel is made of un-obtainium. Sadly, un-obtainium is also soft and the finish wears away quickly. It is extremely difficult to find a nice example of this one.

    And the manual version 136.027 with 613 movement from 1966. Sorry for the shameless "group" pic but since the bezel is made of un-obtainium (well done redpcar) she doesn't get as much wrist time. Solid watch, a little on the light side IMHO.

    1967 OMEGA Seamaster 120 manual wind no date, EPSA case

    Late 1950's and thru out the 1960's SCUBA diving and SNORKELING was gaining popularity amongst the affluent and upper middle class as a leisure sport. Omega's big, heavy divers watches designed for professional divers did not suit the new emerging demographic.

    In 1966 Omega introduced the SEAMASTER 120 line that came in both manual and automatic models with and without a date complication. A watch suitable for "TOWN, COUNTRY and SEA" as Omega stated, designed for the Gentleman @ 38MM minus crown (a smaller @31MM version for the Lady) as a sport /leisure/casual wrist watch.

    The Gentleman's SEAMASTER 120 came in 4 models:

    Case ref.# - 135.027 ....... Manual Movement, No Date, Caliber 601
    Case ref.# - 136.027 ........ Manual Movement, with Date, Caliber 611 / 613
    Case ref.# - 165.027 ........ Auto Movement, No Date, Caliber 552
    Case ref.# - 166.027 ........ Auto Movement, with Date, Cailber 565

    OMEGA cal. 601 - 17 Jewels, Manual Wind, No Date Complication
