G-Shock
Having had a mid-det failure of my 'det digital' Watch, I got a $60 G-Shock from the BX.
3 Time Zones.
Solar powered so no battery faffs
decent back light
stacks of alarms, stopwatch & timer functions.
Cheap as chips and I'm wearing it pretty much all the time as I don't have to worry about it.
You can get a radio synchronized one for double the price, but I'm not sure it works in the desert.
