I bought this watch couple months ago and use it very often. First of all the price is very reasonable and with amazon return policy you can't go wrong. I have few watches so this isn't my first one.
One thing about 'atomic' watches is that they have to be at cetain place to synchronize, but this one has very sensitive receiver and synchronizes everyday.
It has a lot of built-in functions some of them useless for me like 3 alarms because they aren't laud enough. Other like having other time zones, day date and you don't have to change the battery.
The sequence of initial setting is in wrong order in the manual. You have to set the daylight saving in your city before you select it as you local time zone, but this is minor. It is very accrate of course and light weight.
