First released in 2006, Cartier’s Rotonde collection belongs to a fairly new pillar of wristwatches manufactured and launched by the firm. Although inspired by a Comet Day & Night clock from 1920, the Rotonde iterates a modern finesse to a traditional concept. The wristwatch features an interesting way to tell time via retrograde hours indicated by a decorative wheel consisting of a sun and moon rotating through a large aperture landing on the outer hour track in Roman numerals. The bottom half of the dial consists of 7 small apertures depicting the moon phases.
