  • 寶璣,「Equation Marchante - Horloger De La Marine」,非常罕有鉑金陀飛輪萬年曆自動腕錶,配時間等式及閏年顯示,約2017年。首次於拍賣市場出現。附錶盒、證書及說明書。

    In 2017, Breguet unveiled the most complicated watch in their Marine collection, the Ref. 5887 "Equation Marchante - Horloger De La Marine". The Marine collection revels in contemporary and sporty design cues, based on traditional tenets of their founder Abraham Louis Breguet (1747-1823), who was made a chronometer maker to the French Navy in 1815.

    Contemporary in its design, the Ref. 5887 sits proudly on the wrist in a 43.9mm platinum case. The engraved central part of the dial hints at blue ocean waves, whilst the off-center tourbillon and "running" equation of time at 5 o'clock allude to classic Breguet's signature style. The traditional Breguet hour and minute hands highlighted with luminous accents add another sporty element, whilst the anchor hand for the retrograde date and running solar hand with faceted golden sun add a modern flair.

    The Ref. 5887 showcases Breguet's most-famed complication, the Tourbillon, alongside "running" Equation of Time, a Perpetual Calendar with Retrograde Date, Leap Year and Power Reserve Indication in its 16¾ lignes Calibre 581DPE. Equation of Time represents the difference between mean solar time and apparent solar time, or the difference between the time shown on a clock verses a sundial. The time it takes for the sun to return to the same point in the sky is not exactly 24 hours on any given day and can range from 14 minutes shorter to approximately 16 minutes longer than a mean solar day. The Equation of Time kidney-shaped cam visible alongside the 60-second tourbillon aperture controls the running solar hand and how far behind or ahead it runs from the minute hand.

    This mesmerizing watch continues its riveting show from its sapphire crystal display back, where a clever, peripheral rotor winding system powers this highly complicated watch and best shows off the engraved bridges depicting a French Naval scene and Compass Rose. More impressive and adding to the watch's wearability is the fact the Calibre 581DPE is based on the Breguet Classique Tourbillon Extra-Plat Automatique Ref. 5377, thus minimizing the watch's thickness to 11.5mm. The Silicon escapement wheel, inverted lateral lever with silicon pallets and silicon balance spring adds the final touch of modern innovation, as it reduces the need for oil and are unaffected by magnetism.

    To the best our our knowledge, this is the first time a Breguet Ref. 5887 "Equation Marchante - Horloger De La Marine" has appeared at auction.
