The Marine Tourbillon Équation Marchante 5887 combines a sporty aesthetic with a highly complicated movement and the finest hand decoration. Breguet offers this model in rose gold with a gold dial in slate grey.

When it debuted the Marine Tourbillon Équation Marchante 5887, Breguet wove together three threads from its history. First, its legacy of the invention of the tourbillon, patented by founder Abraham-Louis Breguet in 1801. Important as well is its unparalleled patrimony in the field of complicated watches: Marine 5887 includes, in addition to the latest generation tourbillon, a perpetual calendar and an equation of time. Third, by uniting these two historic pillars of the house in a Marine timepiece, Breguet recalls the founder’s appointment in 1815 by the King of France, Louis XVIII as Horloger de la Marine Royale, which made him the official watchmaker of the French Navy.

The Marine Tourbillon Équation Marchante includes two minute hands, a traditional civil minute hand and a second minute hand showing solar time directly. The running equation of time display of this Marine model is paired with a perpetual calendar. The movement accounts for all of the irregularities of the four-year calendar cycle, the months of 30 or 31 days, and the month of February of 28 or 29 days during the leap year. The movement of this Grande Complication model is derived from the extra-thin self-winding tourbillon caliber 581. The basic notions of tourbillon design rooted in Abraham-Louis Breguet’s patent remain unchanged: the timekeeping elements of the watch, its balance wheel, spiral, and the escapement, are placed within a carriage that makes one rotation per minute so as to cancel out rate errors resulting from gravitational forces. Modern technology played a prominent role, as well, in the tourbillon design as the carriage is made of titanium and the balance wheel’s spiral as well as the escape wheel are fashioned in silicon.
