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.
Abraham-Louis Breguet, Watchmaker to the Royal Navy
The origins of the contemporary collection trace back to the prestigious title "Watchmaker to the French Royal Navy" awarded to Abraham-Louis Breguet, founder of the eponymous workshop in 1775, by Louis XVIII on October 27th, 1815, a year after he was appointed a member of the Board of Longitude.

Montres Breguet's rich heritage, which connects the House to the oceans and navigation, has paved the way for the Marine collection, a family of timepieces with a sporty silhouette and signature aesthetics that clearly evoke the codes of the marine world: a dial decorated with a hand guilloché "wave" motif, a crown guard with an undulating profile, a hand finished with an anchor among other distinctive features.
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 calendarActing 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.
TourbillonCreated 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.

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.

581DR calibre, the new
Marine Équation Marchante by
Breguet 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 power reserve
for a self-winding model. This 80-hour autonomy is displayed through an
aperture between 7 and 9 o’clock.

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.

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.

Since , the sun has been used as the basis of time. Nonetheless, the
visible motion of the sun – the true solar time indicated on sundials –
is irregular. 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. Given that the sun’s various positions in
the sky are reproduced in an identical manner on the same dates,
watchmakers can “program” them by means of a special cam.
Click, to see the large size. ▶ FOTO
The latter is shaped like a figure 8
and mechanically reproduces the path of the sun’s successive positions,
called an analemma curve. Requiring extremely accurate execution, the
cam is coupled with a feeler-spindle that drives an equation lever
serving to indicate the difference between civil time and solar time (-16 to +14
minutes). This read-off is generally provided on a sector or subdial.

It is then up to the user to mentally add or subtract the difference
displayed in relation to mean time in order to calculate true solar
time. The new Marine Équation Marchante from Breguet supersedes
this principle. It simultaneously indicates civil time and true time by
means of two separate minutes hands. The running solar hand, adorned
with a facetted golden sun, provides a direct reading of solar time
minutes that is both quicker and more user-friendly.

This apparently simplicity conceals an arduous construction process that
few watchmakers are capable of achieving. The solar minutes hand has to
meet two imperative demands: it must sweep in a conventional way around
the dial, like the civil minutes hand, while also daily moving away
from the latter by a distance that varies in accordance with the
analemma curve, in order to display the equation.
Click, to see the large size. ▶ BIG FOTO 
Breguet was able to accomplish this by equipping its running
solar hand with a differential gear powered by two rotation sources
operating entirely independently: the rotation of civil minutes, and
that controlled by the lever in contact with the equation of time cam,
which makes one full turn per year.
Breguet has developed an
extremely slim equation cam borne by a transparent sapphire disc also
serving to correct the equation of time by month.
Aesthetic poetry: the open sea under the night sky
Presented in 👉 2017, the Marine Equation Marchante 5887 initially featured a 43.9 mm diameter case available in platinum or pink gold with an ultramarine face.

Three years later for the 220th anniversary of the tourbillon, the collection was expanded to include the warm reflections of pink gold combined with a chocolate-coloured dial.
This autumn, Montres Breguet completes the series by choosing the gentle strength of platinum for its fluted case. This precious grey metal is combined with the black hue for the "wave" guilloché dial, evoking the image of an ocean cradled by the silvery glow of the Moon. The complexity that the running equation of time brings to this model is naturally complemented on this “Grande Complication”
by a perpetual calendar. Two apertures – one between 10 and 11 o’clock
and the other between 1 and 2 o’clock – respectively display the days of
the week as well as the months and the leap-year cycle.

The date
appears inside the chapter ring by means of a retrograde hand tipped
with an anchor motif and sweeping across an arc running from 9 to 3
o’clock. The dial layout of the information has been carefully designed
to ensure simple and intuitive linear reading, along with impeccable
visual appeal.

Breguet hands with Super-LumiNova® filled tips indicating the hours and minutes, the hand with a golden circle indicating the solar time, and finally the hand with an anchor indicating the date. Raised blackened gold appliques Roman numerals are set on a wide circular-brushed ring, interspersed with luminescent dots and surmounted by gold hour-markers in the shape of nautical pennants.

A truly magnificent timepiece, the new
Marine Équation Marchante by
Breguet sets
the tone. It features new aesthetic signature codes giving it a modern
and dynamic appearance: central lugs combining polished and
satin-brushed surfaces; more open fluting, with visible flanks; a crown
topped with a polished “
B” against a sandblasted background; as well as a crown adorned with a chamfered and satin-brushed wave motif.
