My best ever Watch
I have used this watch for several years now. It keeps time flawlessly with satellite/GPS update only needed perhaps once every month (i'm talking about getting it back on the second as opposed to being perhaps 1/2 to one second off WWV. My watch has been jarred at some point, and the second hand is offset from the correct time by exactly one second. I'm sure a watchmaker could correct that quickly and at minimal expense if I desired to do so. In addition, the outer (rotating bezel) for the E6B time, speed, distance, and conversion functions has lost much of it's dark numbering due to being worn constantly - I suppose that is to be expected. Otherwise - it's the greatest watch I've ever owned and I wouldn't be without it (or another one like it). At my age now, it's a bit hard to see some of the numbers on the calculator bezel, however I feel that feature is more of a gimmick than a practical feature anyway. If you are interested in celestial navigation - this watch is the PERFECT solution for precisely accurate time. It replaces the requirement for a good chronometer, and if satellite/gps updated periodically, does away with chronometer rating, and the necessary corrections that need be applied. I love this watch.
