EXPLORERS BREVET #103. A 12 HOUR CHRONOGRAPH POCKET WATCH MOVEMENT ONLY--- with  2 dials.-- ONE TIME Dial  AND ONE Dial A 12 HOUR RECORDER  also with A  SWEEP SECOND CHRONOGRAPH WITH SUB SECONDS DIAL.
Movement for a  very rare pocket watch with chronograph function. This pocket watch movement shows the minutes recorded by the chronograph but also the full hours-- Meaning this pocket watch was made for those who were required to time very long intervals, most likely because of someone’s job ( explorer, mountaineer , surveyor, mariner, observatory ).
Not to be mistaken with a ‘normal’ chronograph, this high quality piece times to 1/5 decimal of a second, minutes and up to 12 hours. Compared to your usual chronograph that times up to 30 minutes this is a big difference, not only in numbers but also considering the fact that it is quite a bit more complicated.
The white enamel dial is with a sub dial on the left side with the line ‘Temps Vrai’ above meaning ‘True Time’ showing the hour and minutes of the day. On the right side we see another sub dial with ‘Compteur’ written above meaning the ‘Counter’ of the chronograph. A centered sweep chronograph seconds hand and decentralized ‘normal’ seconds hand.
