This is a clock that has it all, classic design and size but no less lovely for all that! Computer used the word one could take for this pendulum, it is "plug and play"! It installs and she does everything alone! No fuss with it, the packaging is strong (well protected with bubble wrap) and I even was surprised to find a "AA" battery that comes with. So just remove the protection of the battery so that it turns on it alone and hear 5 to 10 minutes (depending on location) to be at the exact time thanks to radio signal piloted. It is mentioned a 2 year warranty and is made in Germany, therefore a guarantee of quality normally!
