The Rotonde de Cartier Astrocalendaire Replica main feature has to be the multi-tier, concentrically laid out perpetual calendar. As fancy as that sounds, the result is stunningly straight-forward: situated just off the very centre of the watch, three rings are surrounding the flying tourbillon, with each one of them dedicated to the indication of the day of the week, the month and the date, respectively. Owing to this configuration – reminiscent of ancient Roman amphitheaters – Cartier’s perpetual calendar offers legibility that few other watch do.
On all three tiers the exact date is marked by blued brackets that seem to float over the rings’ markings. Reading information from the three tiers and their rectangular frames does suffer in some poor lighting conditions, but the Cheapway the rings are stacked so close together makes for a quicker and easier reading compared to most other calendar watches.
Having said that, one indication is missing – although it may not be instantly obvious even for those with a weak spot for this complication -, which is the display of leap years. Visible through the transparent case back, the leap and non-leap years are indicated by a hand set on one of the movement’s bridges. Watches
Unusually suppressed by other elements – but positioned in the center of attention nonetheless – is the flying tourbillon, sporting the well-known capital “C” on its bridge. The in-house designed and manufactured movement, titled 9459 MC, LuxuryWatch is actually assembled in Cartier’s haute horlogerie workshop in Geneva and so it is qualified for the Geneva Seal.
