A Masterpiece of Astronomical Complications
The Astronomic Souveraine was designed to incorporate an extraordinary array of complications without compromising elegance or legibility. It features displays for mean time, sidereal time, equation of time, sunrise and sunset times, moonphase, and a tourbillon for enhanced precision. Adding to its grandeur, the watch also houses a minute repeater and annual calendar functions, all powered by an 18k rose gold movement finished to the brand’s highest standards.
The platinum case frames a meticulously arranged dial that balances complexity with harmony, making the Astronomic Souveraine not only a horological achievement but also a wearable piece of art. With its technical depth and limited availability, it remains one of the most sought-after watches among seasoned collectors.

Frequently Asked Questions.
It combines mean solar time with sidereal time, an equation-of-time scale, sunrise/sunset shutters that visualise daylight length, a moonphase, and a second time zone. The shutters at 12 o’clock expand or contract with the seasons, while the equation-of-time and sidereal displays track the difference between civil time and the Earth’s actual motion.
The tourbillon improves rate stability, while the remontoir d’égalité delivers constant force to the escapement at regular intervals. Together they help the watch maintain steady amplitude despite the energy demands of multiple complications and the minute repeater.
You set local time, date, and location parameters through the crown and correctors; the sunrise/sunset shutters, equation-of-time and sidereal indications then follow those settings. Once adjusted, all displays advance coherently with the calendar and time you’ve set.
It is typically cased in stainless steel in a large format designed to house the grand-complication calibre. Despite the size, balanced lugs and a curved profile make it wearable; most owners treat it as a careful-use piece, given its mechanical complexity.
