    Since it has already been discovered by the list that it is easier to
    maintain temperatures above ambient, eg. crystal heaters in HF radios,
    than below, i would suggest a small well insulated box with a
    thermostatically controlled heater (one or two watts, 12-15v DC?). The
    Watch could be viewed through a double or triple insulated glass window
    so as to not disturb the thermal equilibrium.  This would be a nice
    project not beyond the capabilities of many of us. A couple of LED's to
    indicate operating temperature and power on and it would be a nice piece
    of kit to have at the nav station.
