Raymond Weil Watch - 39.5mm Maestro Moon Phase Automatic
The maestro moon phase gives a new meaning to space & time. A moon phase aperture at six o’clock adds an element of otherworldly romance to this classic watch. Moon phase displays were common on clocks & pocket watches dating back to the renaissance period. Combining art & science, this feature demonstrates watchmaking technical mastery & know how.
Moon phase watches show the various phases of the moon, which has always provided time with an orientation. The moon was the first method of telling the passing of months.
A “moon phase” is the lighted area of the moon that is visible as it travels around the earth. Its journey is exactly 29 days, 12 hours, 44 minutes & 2.9 seconds.
To set your maestro moon phase watch, you must determine the date of the last full moon in the lunar cycle. Once you have the number of days, pull out the crown and twist counter clockwise. Turn once for each day elapsed.
While this measurement of time may be antiquated; it still represents historical craftsmanship & gives this maestro model a whimsical vintage appeal.
The combined open balance wheelon this maestro watch reveals the “heart of the movement”. It is just a glimpse into the precision, quality, and technical assembly inside the refined design of a 39.5mm case.
