Just arrived: the Breguet Marine Équation Marchante

12/12/2017

We have just taken delivery of the Breguet Marine Équation Marchante. This fascinating watch was presented at Baselworld as a homage to the unique heritage of Abraham Louis Breguet. This "Grande Complication" marks the start of a new era for the contemporary Marine collection. The equation of time is one of the rarest and most fascinating horological complications. It serves to display the difference between mean solar time, corresponding to civil or standard hours and minutes, and true solar time, meaning the actual solar hours and minutes. With the improvement of timekeeping precision, watches and clocks became the basis of time and true solar time was replaced by mean solar time, within which each day has the same duration of exactly 24 hours. Mean solar time may show a discrepancy with true solar time ranging from minus 16 minutes to plus 14 minutes. On just four days a year, the two times are exactly the same.

The complexity that the running equation of time brings to this model is naturally complemented on this "Grande Complication" by a perpetual calendar. This watch also flaunts a third complication that is noteworthy in its own right: a 60-second tourbillon with a titanium carriage housing a Breguet balance with a silicon balance spring. This innovative characteristic notably enables the balance wheel to achieve a 4Hz frequency, while maintaining a particularly comfortable 80-hour power reserve for a self-winding model. We now have this watch in stock. Pay us a visit - we would be pleased to show you this world-exclusive timepiece.
