This rare piece is among the twenty or so watches known as "remontoir perpétuel à décrochement". This ingenious mechanism was patented in 1867 by Benjamin Haas. It allows to wind the movement by closing the case cover, transmitting the energy via two levers to a ratchet wheel on the barrel arbour.
The watch is a double dials piece with on one side a full white enamel dial for the hours, minutes, subsidiary seconds as well as the moon-phases. On the other side, the semi skeletonized dial displays the date and the day while revealing the beautiful mechanism. Interestingly, the watch features a perpetual calendar that focuses on the date, day and moon-phases and voluntarily omits the month and leap-year indication. Additionally, the watch has the minute repeating complication, activated by the slide to the band of the case.
The case is cleverly constructed and particularly worth of interest. To open on side of the hunting case, the bow has to be in the opposite direction. That way, the owner can decide which dial he would like to reveal, still keeping the other one protected.
