Jacob & Co. Astronomia Maestro




 Jacob & Co. Astronomia Maestro – Gravity Tri-Axis Tourbillon Minute Repeater Clockwork

Jacob & Co. presents a new masterpiece from its wildly successful Astronomia collection. After using extremely complex minute repeaters in other collections, Arabo, the founder of Jacob & Co., decided to add a minute repeater with glockenspiel reeds to the already super-complex Astronomia.Jacob & Co. Epic X replica

The minute repeater is the most prized complication of collectors and one of the most difficult complications for watchmakers to conceive. Only a few manufactories have managed to create a minute repeater, and when combined with other high-level complications such as the Astronomia's three-axis tourbillon and rotating mechanism, the Astronomia Maestro is a true feat of watchmaking technology, taking more than three years to complete. It took years of development to get ready for release this year.

When activated, the three spiral gongs of the Astronomia Maestro chime strike the hours, 15 minutes and minutes at a glance and, thanks to the sapphire crystal case, sound beautiful.cheap watches for sale

The large sapphire crystal case has been a consistent design element of the Jacob & Co. Astronomia collection since the launch of the first Astronomia in 2014. The transparency of the case allows the movement of the gravity triaxial tourbillon to be clearly seen from multiple angles, and the three raised spiral gongs of the minute repeater clockwork are clearly visible at six o'clock.

At the heart of the Astronomia Maestro is the exceptional timepiece craftsmanship for which Jacob & Co. is renowned. The three-axis tourbillon counteracts the effect of gravity on the moving parts of the movement, as the tourbillon cage rotates in 60 seconds and completes one revolution on its own in 90 seconds, while the entire tourbillon makes one revolution in 10 minutes around the central axis of the watch. lock up. 1-carat, 288-faceted Jacob Cut® diamonds, magnesium-lacquered blue globe, hand-painted astronaut rotating in 40 seconds, and moon phases and date, including two hemispherical Jacob-cut diamonds (one carat total) with dial surround The tourbillon travels together.discount replica watches

The background of this mechanical work is pure aventurine, making it look like a dark blue starry sky, with hand-painted galaxies and planets as details.
