Louis Moinet Tempograph
Written by James Matthews
Tempograph original technology is absolutely unique in its kind. It consists in the first and only 10-second retrograde complication activated by a visible cam mechanism. This invention has been patented (patent pending), since Tempograph can be considered as one of the most creative watches on today’s market.
The distinctive feature of Tempograph is its retrograde seconds mechanism, which is constantly on the move. The watch is a non-stop visual delight, enlivened by the regular ballet of a hand that marks off the time in ten-second segments alternating with an instant retrograding motion. At 9 o’clock, the cam mechanism is truly spectacular and has been left visible so as to enable the wearer to admire it in action. The cam is composed of six teeth and performs one rotation per minute. It releases a titanium lever adjusted to the 100th of a gram.
