Nice design but features to review

The design is as pictured. Plastic but well made. Very silent clock. You do not hear at all the needles turn and the second turn smoothly. This gives a very nice visual.
There are 3 buttons behind that make the various settings:
- A button to begin receiving the radio signal and set the time clock .: needles turn by themselves.
- A button to reset the clock: the hands start all 12
- A button to set the time manually and use the clock as quartz (ignoring the radio signal)
You should know that the radio signal is that of Frankfurt, Germany.

I have not managed to get the French time. So either the clock does not receive the signal correctly to adjust either the signal sent ignores time zones. If someone has managed to get the French and correct time, I'm interested in how he did it.

EDIT: After setting the time manually, the clock is working. I was able to attend the auto search time in the night and after the first manual setting, the clock could retain / regain early.
Perhaps it was a first manual adjustment to set the correct time as reference time for the automatic search ...
