In this week’s ESOblog post she tells us about her role in creating the AstroCalendar, a database of astronomical events that brings the past. Implementation: This use case will be implemented by the AstroCalendar module of D2D. AstroCalendar is a project of ESO, for the ESO Supernova Planetarium.

Today we have something for you from the opposite end of the spectrum.

The Data2Dome

Here is the Rotonde de Cartier Astrocalendaire, a perpetual calendar with a flying tourbillon that uses a multi-tier circular display for the perpetual calendar and a mechanism that is almost entirely free from the typical levers and springs.

This is a seriously complicated watch that introduces a number of important new technologies, plus it just looks like it means business.

Early live photos and details after the jump. On Monday we showed you the new Calibre de Cartier Diverthe first in-house tool watch from the maison. The perpetual calendar indicators are a bit nontraditional on this watch, with retrograde days at 6 o’clock and date around the perimeter of the dial. But the Astrocalendaire takes nontraditional to a totally different level. The perpetual calendar indicators here are a set of three tiered rings that surround the central flying tourbillon with its signature C-shaped cage.

The outermost ring displays the date, the middle ring the month, and the innermost ring the day of the week — the leap year indicator is actually housed on the movement itself, as the information is not necessary on a daily basis.

Astfocalendarium small blue windows are actually protrusions from geared wheels that turn slowly as the various indicators advance. Time, date, and month are all set via the crown, while a simple corrector advances the day.

The crown-adjusted functions go both backwards and forwards smoothly, something that can’t be said of most perpetuals. The reason for this is that most perpetual calendars use a series of levers and springs to store up power and advance the indicators.

Not this perpetual calendar. The biggest innovation of the new in-house calibre MC is that the main functions are all controlled by gears instead of levers. In addition to allowing the wearer to set the watch in both directions, it greatly improves durability and reduces the risk of breakage. There is a special set of nested gears that Cartier is calling “the Brain,” which is the central feature of this new movement, but we’ll have more on that for you from SIHH At 32mm wide and 8. It is automatically wound via the large winding rotor, which you can see through the caseback.

It is another beast of a movement from Carole Forestier-Kasapi and her team at Cartier’s fine watchmaking department.

Just looking at this movement, you can tell it is not like your usual perpetual calendar. The fully cased watch comes in at 45mm across and The case, crown, and bezel are all platinum, though the black alligator strap is held closed by an 18k white gold buckle.

For a watch of this size, it sits reasonably well on the wrist, though I don’t see this sliding under a cuff under any circumstances. Reading the circular mechanism becomes intuitive very quickly.

In poor lighting, it’s not the easiest to see, but that’s a problem that plagues many complicated dials. The Rotonde de Cartier Astrocalendaire is a limited edition of only numbered pieces. Visit Cartier for more. Talking Watches With Fred Savage.
