    My own "personal minimums" for offshore navigation would probably
    include at least 3 of everything critical for navigation that might be
    subject to failure (i.e. 2 backups) - though I think 2 radios capable
    of receiving time signals would be enough, probably an HF rig and
    something like a Radio Shack TimeKube (if in range of WWV/WWVH) would
    be adequate.
    
    And quartz watches are cheap enough these days that I think I'd be OK
    with 3 of those (vs. a full-fledged chronometer), though if they didn't
    automatically synchronize with a time signal I'd obviously want to know
    how much time they gain/lose in a 24-hour period.
