Here is more explanation:
I need a stand-alone, easily portable unit with display; the unit may be used
where GPS, cell phone, or WWVB are not available. Low power consumption is
highly desirable.
I have seen advertisements of marine quartz chronometers listing an accuracy as
good as <0.01 second/day at a constant temperature of 22 C. Has anyone had
experience with a marine quartz chronometers? If so, how much did the accuracy
vary with temperature?
Thanks for the suggestions about pickup coils; I had hoped a coil would detect
the clock movement well enough to compare to a standard 1 PPS. I have a
Motorola GPS timing module and a storage oscilloscope for comparison.
