Throughout his career, A.- L. Breguet consistently demonstrated his exceptional mastery of time measurement. His strong involvement and his revolutionary developments earned him significant recognition and numerous honours. Renowned the length and breadth of Europe, Breguet found a particularly active admirer in Louis XVIII, king of France. In 1814, the latter appointed him a member of the Bureau des longitudes in Paris. Breguet became the horological authority, notably for the calculation of longitudes at sea. As an extension of this distinction, through an ordinance issued on October 27th 1815, Louis XVIII awarded A.-L. Breguet the official title of chronometer maker to the French Royal Navy.
This was the most prestigious title a horologist could hope to receive, given that the very concept of marine chronometry implied scientific knowledge. It also involved playing a crucial role for the country, as marine chronometers were of capital importance for fleets by making it possible to calculate ships’ positions at sea.
Following in the wake of this unique heritage, the House of Breguet now launches a worldwide exclusive model named the Marine Équation Marchante 5887. 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.
The new Marine Équation Marchante from Breguet 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.
Based on the self-winding 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.
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. This “Grande Complication” comes with a 43.9mm-diameter case in rose gold or platinum. The rose gold version frames a silvered dial and an anthracite movement, while the platinum interpretation has a blue dial and a rhodium-plated movement. Elegance, legibility and aesthetic balance are the keynote features of these two equally sumptuous models.
