In the Breguet watch collections, the Marine Équation Marchante 5887 stands out with its unexpected new-look display of the equation of time.

Equation of time watches show the difference between average solar time and real solar time, the one used in our daily lives. Breguet has decided to give it a new look with a “running” (marchante) equation of time. In concrete terms, the Marine Équation Marchante 5887, with the help of two totally independent rotation mechanisms, shows both civil time and real time with two separate minute hands. The “running” solar hand is distinguished by a facetted sun at its tip, showing the minutes in solar time at a glance. The two hands display the real gap between the two kinds of time.

Another strong point for the Marine Équation Marchante 5887 is a perpetual calendar that is automatically corrected according to the length of the month. Two counters, one between 10 and 11 o’clock and the other between 1 and 2 o’clock, show the days and months, respectively. The date is displayed on a retrograde scale on a arc between 9 and 3 o’clock.

The watch is available in two versions. One has a platinum case of 43.9mm in diameter and a blue dial made of gold. The other is dressed in rose gold and has a silver-gold dial. They are both driven by an exceptional mechanism, the calibre 581DPE, individually numbered and manufactured by Breguet. The precision of this self-winding movement is improved by the presence of a 60-second tourbillon and a silicon balance. This mechanism is visible through the case back and has a comfortable power reserve of 80 hours, displayed discreetly on the dial in a counter between 7 and 9 o’clock.

Price: 209 500 EUR (rose gold version) – 224 500 EUR (platinum version)
