I can't help but offer a cheap and simple solution to your quest, even
though it is obvious.  Why not use a cheap quartz clock for your
reference time.  Roll your own mathematical function that modifies
the reference time in a manner that simulates a mechanical
chronometer.  I am certain you can find plenty of information
regarding the accuracy of mechanical chronometers.  You could
even simulate simply a typical three chronometer arrangement
based on one quartz reference.  This involves minimal initial buy in
cost and certainly does not require any service fees later.  Just think
of the fun you could have tinkering with the function.

I think I have just saved you a bundle of money, what will you spend
it on?

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
6mx

At 1500.00 us dollars the price does not seem out of line. What I
am
concerned about though is either learning to maintain the device or
finding
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
device
in good running condition?
