And some interesting side note, as stated by Manuel Emch (CEO of Jaquet-Droz):
"Jaquet Droz administarion and facility is located in
La Chaux-de-Fonds at Rue Jaquet Droz No 5 (Jaquet Droz Street) at the very same location were the first manufacturing facility was built up by Pierre Jaquet Droz in 1738! (Unfotunately not the original farmhouse but a very nice building dating from the 19th century)
We put a lot of attention in preserving our history and heritage.
We also constituted the biggest collection of antique Jaquet Droz timepiece... displayed in our workshop."
