    Help dating Bristol Certina

    I'm trying to learn a bit more about this watch that I bought about a year ago. It has grown on me and is becoming one of my favorites. I would like to find out its approximate date and if anyone would know what the engraving on the caseback refers to. Thanks.

    My gut feeling was: late 1960s to early 1970s - but then Ranfft tells us that the movement was made from 1975-77:

    AB Elementhus was started in 1950 and made everything for building houses so 1975 sounds just right for someone to get a watch after 25 years. There were around 100 workers to begin with but in 1975 there were over 1000 workers. I have found that the M version of the 25-651 can be found as early as 1973 but that they were first branded as such from 1975.
