A grand complication in platinum armour
The Marine Tourbillon Equation Marchante 5887, standing as the technical flagship of the Marine collection, embodies a mysterious aura and adopts a solid platinum armour to house its movement, Calibre 581DPE.
A complication as exceptional as this is mesmerising, the Equation Marchante records the difference between local time - the time that punctuates our daily lives - and solar time - the time dictated by the earth’s rotation relative to the sun. Featuring a perpetual calendar and a tourbillon, this Marine piece is made in platinum, a rare and durable precious metal renowned for its remarkable resistance to corrosion and enduring brilliance.
Marine Tourbillon Equation Marchante 5887, ambassador of Breguet expertise
This highly technical timepiece, featuring three mechanical high complications: the running equation of time, perpetual calendar, and tourbillon, - driven by the self-winding Calibre 581DPE, embodies the spirit of innovation that has characterised the brand since its inception.

Equation Marchante
This exceptional complication simultaneously displays the difference between mean solar time (calendar hours and minutes) and true solar time (used since ancient times, it can maximally deviate by up to 14 minutes late or 16 minutes early) thanks to an equation of time cam linked to a feeler to drive the equation lever.
With the Marine 5887, reading the time is instantaneous thanks to its two minute hands: one Breguet-style with a luminescent tip for calendar time, and the other, finished with a gold plated, diamond polished and fluted ring, for solar time.
Perpetual calendar
Acting like a mechanical diary, this complication indicates the date with an anchor-shaped retrograde hand that follows an arc-shaped scale, graduated from 1 to 31, located in the upper part of the dial. The day, month and leap year are displayed in two open windows at 10.30 and 1.30. This information is detailed in white on a black background for easy legibility.
Tourbillon
Created by Abraham-Louis Breguet, patented in 1801 to counter the adverse effects of gravity on the running of mechanical movements in pocket watches, features a titanium cage and a Breguet balance-spring made in silicon at around 5 o'clock.
To enhance the functionalities of the Marine Equation Marchante 5887, a blued gauge positioned between 7 and 8.30 o’clock provides information on the level of stored energy available, which amounts to 80 hours when the watch is fully wound.
Aesthetic poetry
An engraved platinum peripheral oscillating weight decorated with a "wave" motif wraps around the hand chiselled back of the calibre 581DPE depicting the silhouette of the Royal Louis, a Royal Navy warship commissioned in 1752. The barrel is decorated with a hand engraved compass rose.
Guilloché and engraving are delicate arts, executed by hand by exceptional artisans, true masters of their craft. Each pattern is patiently sculpted, each line traced with infinite precision, breathing unique, almost lifelike character into each timepiece. These pieces become much more than mere timepieces: they capture the essence of time and the soul of the artisan, offering a rare luxury — that of wearing an exclusive and inimitable work of art.
