Performance-wise, it's upscale.
Everything is assembled with precision and needles are keyed to perfection.
Robustness is also the rendezvous. I have mine for several months and the few unlucky shots that she was able to have altered or its functioning nor the case.
Precision for the Party Automatic time: the watch is radio controlled and starts on time every night by capturing an atomic clock signal.
For France, the two transmitters are located in the UK and Germany. These transmitters are easily received within a radius of 500 km and can be received up to 1500 km. Beyond that, it's less obvious.
I tested the update on trips and I can say that the signal is picked up southern Corsica.
So for France, provided that the relief does not do too much screen you should be able to benefit from this update.
Only downside: the prominent crown can mark the upper hand in rare cases ... but nothing too bad (I wear left).
Finally, this watch is truly a marvel of technology.
For the price, it rather approaches a luxury product, but worth the trip.
