    Re: mechanical chronometers

    I did a quick web search this morning and came up with 2 sites that include
    pretty good pictures of the Hamilton M-23.
    Robert Gainer and I had an exchange on the other list about this and the
    M-21 he has and uses.
    This is, by far, the best navigational watch made. The Japanese, Germans and
    especially the Soviets never came close to making a navigational watch as
    nice as these. I had no idea what quality I purchased at the time. It wasn't
    until I took it to a watch repair shop to give it its 1st yearly cleaning
    that I was made aware of what I had. Like I stated: mine was purchased for
    about $200.00 in '83 and it never, ever failed me. I kept (still do) it,
    ready for use, in my sextant case.

    Scroll down for pictures and descriptions.

    Can you tell me more about this Hamilton watch?  What kind of rate does it
    keep? What is the case constructed from? Any photos?
