Shows very good rule. Any time that the radio controlled is done in good condition, still must make some manual handling yourself; for example, the time zone '' P AR 'of Paris for France,' 'DST' 'Winter pass / summer and summer / winter on' 'AT' 'automatically and most importantly, the RCVD, to activate the radio control. Once all these settings are made, it's only happiness, everything is automatic. Not to mention the other very traditional functions such as timer, stopwatch, alarm, 12 or 24 hours, light, etc ... and some less usual, setting the language of days of the week, activation of the beep buttons. I appreciate the sapphire stronger than mineral glass, steel case and bracelet, 9mm is really flat for a watch of this size, solar energy which also charges the battery, phosphorescent needles ... A few caveats, like the clasp with only a single setting, links very difficult to remove, to shorten the bracelet, a light not very effective on a black dial, no day of the week in French and shows a bit heavy. A fourth key to light alone, was also a plus because for manual settings, obligation to go hang three seconds by the lighting. But overall, unless very demanding, it ensures that it is expected, auto setting and quick and easy reading of dials, I recommend it.
