The Breguet Marine Tourbillon Equation Marchante 5887, reference 5887PT/92/5WV, represents the brand’s pursuit of sophisticated horological craftsmanship. Featuring a platinum case, this model combines three complications: a perpetual calendar, a running equation of time, and a 60-second tourbillon. The Marine 5887, rooted in maritime inspiration, marks a comprehensive display of Breguet’s engineering and design.
Caliber 581DPE: Advanced Movement Architecture
Powering the Marine Tourbillon Equation Marchante 5887 is the Caliber 581DPE, a self-winding mechanical movement with 563 components. Equipped with a platinum peripheral oscillating weight, the movement offers an 80-hour power reserve and operates at a frequency of 4 Hz (28,800 vibrations per hour). Technological elements like the silicon balance spring and silicon escapement reduce friction and increase durability, ensuring precise timekeeping.
Complications and Functionality
- Running Equation of Time: This feature enables wearers to track both mean solar time and true solar time. The model includes two minute hands: a Breguet-style luminescent hand for mean time and a distinctive hand for true solar time.
- Perpetual Calendar: The perpetual calendar tracks date, day, month, and leap year, with a retrograde date display across the upper section of the dial. An anchor-shaped counterweight on the date hand enhances readability.
- Tourbillon: Displayed at the 5 o’clock position, the tourbillon is crafted from titanium to optimize weight and efficiency. The lightweight cage reduces gravitational influence, enhancing chronometric performance.
Design and Case Specifications
The 43.9 mm platinum case features Breguet’s signature fluted case middle and is water-resistant to 100 meters. A black 18K gold dial, decorated with a “wave” guilloché pattern, captures Breguet’s marine heritage. Luminescent Roman numerals and pyramid-shaped hour markers provide readability. The dial is shielded by sapphire crystal, with anti-reflective treatment on both sides.
Marine Heritage and Finishing
Honoring Breguet’s legacy as “Watchmaker to the French Royal Navy,” the 5887 features nautical references on its caseback. An engraved depiction of the Royal Louis, an 18th-century French naval vessel, is complemented by a compass rose on the barrel. The entire movement and dial construction meet the standards of Breguet’s exacting craftsmanship, evident in every detail of the piece.
The Breguet Marine Tourbillon Equation Marchante 5887 in platinum exemplifies Breguet’s dedication to advancing horological engineering through aesthetic precision and technical functionality.
