    Re: mechanical chronometers

    I suggest you look into procuring a Hamilton. They may be had at online
    stores or through online auctions.
    I can't remark on the "Poljot 6mx". I'm not familiar with it.
    But I am intimately familiar with using Hamilton products in real world
    applications of navigational time keeping/sights.
    I have used (and still do) the following chrono/stop watch during my active
    career at sea.

    Hamilton Watch Co. Model 23 Type 5742-1 Navigational Watch.

    Great time piece in every department.
    It's a pocket type watch. 19 jewels. Outstanding movement. Internal
    temperature compensation(dissimilar metals or some such).It is relatively
    rugged. Very dependable.
    I can't tell you how much they go for on the open market now days. But they
    aren't cheap. I bought mine in 1983 for around $200.00. Been in service ever
    since. In some really bad environments too.
    Yearly cleanings by a professional watch repair/maintenance service is all
    it had done to it since I owed and used it.
    There are more good serviceable mechanical type watches out there. One just
    has to know where to look.
    Hope the above helped.

    As part of my plan to immerse myself in the time of kepler, newton
    with respect to navigation and other things. I have been researching
    mechanical watches and chronometers. The only manufacturer of
    mechanical timepieces suitable for navigation is Russian the poljot

    At 1500.00 us dollars the price does not seem out of line. What I
    concerned about though is either learning to maintain the device or
    someone who can.

    I know quartz, electronic watches are dirt cheap and more accurate
    but it is outside the parameters of the game. After all I can just
    turn on the gps and make all these subtleties go away.

    Anyone have direct experience with the 6mx and what effort or
    costs would be involved in keeping such a beautiful mechanical
    in good running condition?
