Overview
The Récital 20 Astérium® seamlessly continues the tradition set by its illustrious predecessor, reprising the characteristic shaped case to present an unprecedented mechanical display that showcases the volumes and decoration of the timepiece.
Despite its complexity, setting this timepiece is as quick and easy as for a timepiece with a simple calendar mechanism. The same applies when determining the position of the stars in the sky. To do this, simply point the arrow of the sky map hand northwards. The ellipse opened by this sky map hand outlines the part of the sky that is visible from the wearer’s position at the moment of observation, assuming that the observer is positioned in the center of the elliptical window and enjoys a 360° view.
Design
1
The BOVET 1822 technicians opted to map out the stars and constellations visible from the Earth on a dome of translucent blue quartz, on which they are laser-engraved before being coated in Super-LumiNova® to create a dazzling true-to life sky.
2
To ensure utmost realism, the highest stars in the sky are depicted at the top of the dome while the lowest stars nearer the horizon appear on the periphery of the display aperture.
3
The power reserve and its ten days of autonomy via an internal dome that evolves beneath a fixed hour-marker. The retrograde minutes hand is positioned above it and displayed on the periphery.
4
On the left an hemispheric precision moon phase lingers above the equation of time indicator.
5
The patented double face tourbillon which regulates the Récital 20 Astérium® is equipped with a variable inertia balance wheel.
Features & Functionality
Time is defined by the position of the stars in the sky. Based on this undeniable fact, the night sky was chosen to play the ‘starring’ role in this new exceptional timepiece. Faithful to the underlying principles governing complication development at BOVET 1822, this sky map was designed to be functional, precise and intuitive all at once.

While complex ingenuity went into developing the Astérium®, its mechanism and winding device are designed to be simple, intuitive and reliable, as can be seen by merely turning the timepiece over and looking through the transparent sapphire crystal covering the entire movement. It features a host of graduations linked to the astronomic indications through which a single central hand travels. This hand is driven directly by the annual calendar, and therefore performs a complete rotation once every 365.25 days.
The surface of the lunar ground is engraved by hand before luminescent material is applied, also, by hand. The two circular windows which overhang the dome make it possible to read the age of the moon according to the specific orientation of its crescent, whether one is in the northern hemisphere or the southern hemisphere of the earth.
The domes of the second time zone and the moon phase rotate by the patented mechanism of the radial guidance system, which increases the chronometry and the power reserve of the timepiece.
The precision mechanism that drives this dome gives it an accuracy that requires a correction of one day every 122 years.

To ensure intuitive use and optimal legibility, the hours hand has been designed to execute three functions simultaneously: it indicates the time, points to the north to facilitate map-reading, and carries the elliptical window characteristic of the night sky.
An annual calendar (dates and months) is graduated on the case-back bezel and serves to precisely regulate the night sky. Rapidly setting the annual calendar with the crown disconnects the hours and minutes hands, and enables both the position of the night sky and thus all sidereal information to be adjusted both quickly and easily.

A three-dimensional V-shaped needle allows the collector to select the displayed time zone. This clever and innovative combination, united with the dome, allows optimal readability, despite the reduced diameter of the entire display.
