In terms of features, it's the countdown that is enhanced with a dedicated button for the metal trigger. It is adjustable to the second loan over a range of 24 hours.
The stopwatch is not left with 1,000 hours of reserve !!! To measure an experience, a journey ...
Note that the local time is displayed in all modes except that of the world time which displays the full name of cities.
It is a small dot matrix screen that scrolls the names of cities or modes. The display also comes as the selected function. So the countdown show the tenths of seconds after entering the last measured time.
This watch has a huge and powerful battery to power the vibration alarm. Very practical, you alone are warned of alarms, the battery time (silent chime) or return to normal display after spending all modes. The watch vibrates enough to wake me, especially with the snooze function. I must use it primarily "mute" + "vibe" so totally stealth mode. :-)
A flat on its white LED backlight: it is very powerful and almost dazzling full night. Really not stealth for once. Red diodes have much better function and kept filled cete night vision, a retro electo luminescence type lighting would also have been welcome. this is the only flaw of the watch.
For a larger G-Shock, the "stealth" side is the most beautiful effect. Reversed display is very readable and mineral glass is very well protected.
It is a "tool shows" which offers useful functions both in the kitchen and in sport or traveling. It is neither solar nor atomic but mine varied only 3 seconds in a month and its overkill battery can ensure a long life uncommon.
I recommend it and all its variations. (I almost bought one with the single positive display ...)
Beautiful, practical and solid.
