Just to add a bit here:
I've had one of these for a little over a year now. One drawback to them is
that you don't, can't really, get the kind of instantaneous time-reading as you
can with a braille watch. However, you can read the time while the watch is
under a cuff, and that's very handy in cold weather. The alarm feature is very
handy and easy-to use. I've had mine to two jewelers, one of which sold these
watches, and neither could figure out how to set the hands. If I ever find
someone who can do it, I'm gonna set the hands to Zulu time so I don't have to
mess with them when we change times. BTW, that's my solution for all the
clocks I can't set by myself.
Another thing is that when you get the batteries changed, the jeweler is likely
not going to actually be able to test the level of waterproofing. I understand
there's a gasket involved, and presumably it might be damaged during battery
changes. So if deep sea diving is in your future, you might be better off
sending it to the manufacturer, which I believe is in Switzerland. It is a
very nice watch and seems to be highly accurate. BTW, in case someone doesn't
have it, the phone number for WWV is:
