Essentially this is a modified base Swiss ETA 2892 automatic with a module produced by Dubuis Depraz. The module of course offers a full 12 hour chronograph, but it also offers an annual calendar and moon phase indicator. Each of the chronograph sub dials has the dual purpose of being used for a calendar display. Breitling confusingly does not call it an “annual calendar,” but rather a “leap-year calendar.” While confusing given that “annual calendar” is an industry-wide term, it does make sense as annual calendar implies the calendar needs to be adjusted annually, when in reality it is only on leap years that it needs to be adjusted. The caliber 19 is actually rather complicated and according to Breitling, comprises over 450 parts. Despite all the functions, power reserve is still 42 hours. In addition to the time, annual calendar, and chronograph, the moon phase is an attractive addition to the feature set. What I find interesting is how the calendar functions are adjusted. The crown seems to be used exclusively for winding and the time, while the pushers are for the chronograph. Inset pin pushers around the case (four of them) are used to adjust either the date, day of the week, month, or moon phase). This means that if the calendar functions need to be reset, it is relatively easy and quickly to do so - Please Note: - Second-hand watches are not guaranteed to be leak-proof. - The watch is as shown in the photos.
