The original 2006 Rotonde Jour et Nuit wasn’t exactly a limited production but it was serially produced in very small quantities not numbering more than 100 in pink gold and 100 in white gold. For SIHH 2018, Cartier not only uses a new sapphire disc bearing the “comet” style day and night indicator (itself inspired by a vintage 1920s Cartier clock) but also with a new Cartier manual-wind in-house calibre 9982 MC with 48 hours power reserve.

Historically, vintage Cartier Comet clocks operated on a similar mechanical principle, using decorative elements etched on discs to indicate time, a concept which independent watchmaker Svend Andersen, working with Cartier at the time, took to make the original Jour et Nuit, or Day and Night.

Stylised sun and moon motif rotates once every 24 hours on the SIHH 2018 Cartier Rotonde Day Night Mysterious indicates the hours on the top half of the dial while the blue steel hand indicates retrograde minutes on the bottom half of the satin guilloche brown dial.

The 40mm Cartier Rotonde Jour Nuit Mystérieux is available in 18kt rose or white gold and comes equipped with a sapphire crystal, a sapphire display back, and it is water resistant to 30 meters. Naturally, it comes with Cartier’s signature  Cabochon sapphire crown and worn with a grey alligator leather strap with an 18kt rose or white gold deployant.
