This watch offers a "fluorescence" function that should be helpful to some. As is often the description of the object is poorly made and this function slightly enhanced. That said, she did not really convinced. Not easy to start or to disable, in any case it requires to press a button to turn on and off the screen, the watch can not stay lit long (probably not drain the battery). Moreover, the brightness is very low, not necessarily sufficient to read the time at night ... In short we are in the gadget. It must be said that this watch is not a readability model. Everything is white on black ... It could be a good thing but it results in a cluttered and reading time becomes less instinctive. The datographe is rather small and almost impossible to read after 45 years. The time-setting - and day - is innovative but is rather confusing. Please do not waste the user manual. Finally, the green bracelet is very ugly and quickly stain sweat if you wear this watch for sports for example. Personally I have sacrificed for a rubber strap that goes him better.
It's not all negative, however. The watch is rather original and modern. It is not too heavy. And precision seems to appointment. The seal is no problem so far (I did that for a few weeks).
In summary, if it again I'm not sure I would recommend this watch.
