    Chronometer dials: 12 or 24 hours?
    From: Paul Hirose
    Date: 2009 Jan 18, 14:45 -0800

    Chauvenet (1863) said chronometers should have 24 hour dials, because
    the AM/PM ambiguity of a 12 hour dial made it more difficult to read the
    correct Greenwich time. See the footnote on this page:
    http://books.google.com/books?id=6JlzJHd15vQC&pg=PA56&output=html
    
    So I got on the web to see if later ones had 24 hour dials. After
    looking some pictures at this site, I guess that wasn't the case, at
    least for the common American chronometers:

    Why not? Chauvenet's point seems logical to me.
