Thomas Mercer Nautilus Stone, In Collaboration with Winch Design

In partnership with Winch Design, British marine-chronometer specialist Thomas Mercer has announced the latest iterations of Nautilus, their horological sculpture fusing interior design and astronomical timekeeping.

The word Nautilus derives from the Latin form of the original Ancient Greek: ναυτίλος (nautilos) which means sailor, a title fitting for this unique sculptural time piece, inspired by the ocean.

Taking inspiration from the spiral of the Nautilus shell, Andrew Winch and the design teams at Winch Design drew an elegant shape that follows the golden ratio of the Fibonacci spiral. Quarter-circle arcs are inscribed with the Fibonacci integers (1, 1, 2, 3, 5, 8, 13 and 21), and the curvature of the stone spirals out from the intricate clock face inside. Nature in its purest form is reflected in the proportions of this exquisite timepiece.

The streamlined yet physically imposing sculpture is the signature work of world-renowned Marmor Hotavlje. Available in sodalite, golden onyx and azul cielo marble, this art piece measures 95x69x21 cm and is crafted through a meticulous process, achievable only by the hands of impeccably skilled master stonemasons.

Synonymous with the characteristics of the ocean, this sinuous and sophisticated sculpture meticulously replicates the chambers characteristic of fossil shells and is impeccably crafted from the hands of traditional stonemasons. Epitomizing Winch Design’s ethos of beauty, uniqueness and perfect proportion, Nautilus is the ultimate statement piece for a super yacht, to be showcased and admired.

A visual and mechanical feat, the mechanism of the Nautilus belongs to the exclusive family of astronomical movements, featuring a perpetual calendar which displays the day of the month, the month, and leap year. It also indicates the equation of time, which represents the difference between solar time (varying throughout the year as the earth nears or distances itself from the sun) and the 24-hours-per-day time (based on the worldwide consensus that every day should have the same duration).

In addition to the zodiac, the celestial coordinates are completed with a magnificent 3-D moon sphere providing the different phases, combined with a moon age display showing – within the lunation cycle of 29 days, 44 minutes and 2.8 seconds – the time elapsed since the last new moon.

The mechanism of the clock itself is housed in a truly individual tube case made of extra-white crystal which offers an all-around view of the inner workings, meaning they can be admired in their entirety. The elegant open-work dial magnifies the intricacies of the multi-complicated movement. The hands are steel-made, hand-finished with bluing technique. A final touch of distinction is the double chain-fusee drive which, coupled with barrels, provide the movement with a 30-day power reserve that makes winding it a pleasurable and rare occasion.
