F.P. Journe

I completely understand that he has been very busy with the Paris Boutique, but there are a lot of unanswered questions on the exact workings of the Centigraph, and judging from the amount of posts, significant interest in these answers. Journe has positi... 

Dear Brad, The escapement of the Centigraphe beats at 21600 and counts 6 stops per second. If there was nothing else to regulate the speed of the hand, it would look like the movement of a "foudroyante". Thus, on the axis of the hand there is a 30 teeth w... 

not 1/100th of a second. Why should it be called Centigraphe????? And this answer does not confirm or disprove the Centigraphe's ability to be stopped at a particular 1/60th of a second, i.e., if one has a quick enough hand to start-stop the flying hand, ...

An interesting article on Centrigraphe which I have just found.... Here are some of the excerpts (taken from Revolution Issue 11, by Ian Skellern) Power for the chronograph function- "Journe has used a similiar mainspring configuration to the one he inven... 

This last one seems to suggest that, while the hand is running, it moves once every 1/16th of a second, but that when the user "stops" the hand, it can measure time in increments between two adjacent 1/16ths of a second. Of course, it cannot literally be ...
