    Re: Sisteco Prismatic Compass

    Robert, consider that a new US Army M2 compass (of reasonable quality with
    Tritium dots, not a single capsule) can be bought for less than $70 now.
    Assuming you had a watch maker (or a compasswright?) go to repair your
    compass, they would charge you as much or more for the hour of their labor
    here. Substantially less in Khyber and other places, but I expect something
    similar in your own home.
    
    Then there's the matter of the tritium in the used capsules, classes as an
    ecohazard and toxic waste--so you can bet you'd pay a disposal fee. Plus the
    cost of new capsules.
    
    I'd suggest that what you want is indeed still possible, simply "not
    economically feasible" at the local level the way you'd like it. Replacement
    capsules do exist, they are used in several brands of watches. You could
    obtain a replacement dial from those firms, or capsules from their
    suppliers, but I'm sure you'd wind up paying more than the replacement cost
    of the compass.
    
    Yes, times are changing. Overall, thousands of ships are not being lost at
    sea or wrecked on the rocks every year compared to what once were. So this
    may not be a bad thing after all. After all, tritium capsules are hardly
    "traditional" in any sense of the word, they just shouldn't be used for Real
    Celestial Navigation, now surely?
