Maestro Phase de Lune Semainier

Seven midnight blue hands travel across the heavenly dial of the maestro Phase de Lune Semainier. They give order to the universe, beating in time to the conductor and indicating the phases of the moon, the month, the week, the day, the date, the hours and the minutes. With this unique complication in its collection, and a design of refined elegance, RAYMOND WEIL offers watchmaking enthusiasts an exceptional timepiece.


Time has always enjoyed a privileged relationship with astronomy. In fact, observing the heavens over the centuries has made it possible to measure the passage of time. Astronomical complications were very much in vogue from the Renaissance, first of all in big clocks then in pocket watches with skillfully miniaturized mechanisms. Today, these complications are still just as fascinating, exhibiting the ultimate technical craft and know-how of the watchmaker.

As heir to this great watchmaking tradition, the maestro Phase de Lune Semainier concentrates time and space within a 41mm case diameter. On an almost lunar galvanic dial, seven blued steel batons orchestrate the whole. The four large hands indicating the hours, minutes, seconds, weeks and months revolve around the central part of the dial with its “clou de Paris” decoration. The three small ones indicate the date, the moon phases and the day of the week in three small counter displays (at 3, 6 and 9 o’clock respectively), like astral bodies in orbit around the sun. To regulate the measurement, four push-pieces are very ingeniously set in the polished steel case. This correction system which needs only a simple pressure of the finger was developed by RAYMOND WEIL’s watch designers. The center of this complex system comprises an automatic winding mechanical heart, generating a power reserve of 42 hours that can be seen beating through a sapphire crystal. This marvel of precision and elegance is mounted on a black crocodile-style leather strap with an ardillon buckle, in the truest watchmaking tradition.


With the maestro Phase de Lune Semainier, the conductor RAYMOND WEIL sets the rhythm of time and space. The universe it reveals reflects the image of the Swiss Brand, combining harmony, elegance, tradition and innovation.
