    Marine Chronometers: Seiko QM-10 and Seiko 951-II

    Hi ho, I have taken a lot of pics of my seiko Marine chronometers:









    More close up pics of the inside in here. I would be delighted if retired engineers would comments on the inside of the watches (feel free to link my pics to any comments you may have...):

    Lovely, I have both of these also although the Crystal is defective, the adjustment trimmer has had the core poked through :( . It's still running but not keeping time, shouldn't be a major job to replace the trimmer though.

    Whole chunks of my life come under the heading "it seemed like a good idea at the time".

    I got the Crystal on Thursday. I started it and it was loosing 2 seconds per minute. I have been thinking over the weekend what was wrong. But today it was fine and it has kept the same time as the QM-10 since this morning, spot on. It seems the clock needed some time to work fine after, probably, being stored away for some time. Since the clock is running only at -2 sec from true time, I changed the hour and didn┤t fiddle with the stop seconds. I love watches that self repair. I will keep my fingers closed, nevertheless.... :?

    BTW if someone knows where can this be serviced, please let me know..I think seiko declines to work with them...

    Might I ask where you sourced these, Jose?

    The QM-10 on the web (the bay). The 951 from an Uk company dealing with second hand military vehicles...The first one, around 500 euros incl. shipping and the 951 around 800 euros incl. shipping.

    Thanks, Daddel. In fact it is running fine. The seller has apologised for not telling me that it was usual for these clocks to go astray for 24/48 hours before settling in. But at least if someone else has the same problem, they will know what to do: nothing.... :D

    No, modern marine chronometers are all quartz (although very recent ones are crap, I imagine modern ships rely in GPS/satelites so good timekeeping is not so necessary for good navigation). And anyway marine clocks are never automatic, but hand wound: you know, there is no wrist that can deal with the weight of these.... :wink:
