Patek Philippe has made their mark in the world of horology with many stunning complications, and the Sky Moon Tourbillon 6002G-010 provides a truly astounding coalescence of 13 mechanical engineering wonders. The double-faced wristwatch displays a front dial in blue enamel that has been carefully embellished with champlev_ on the outer circle and cloisonn_ for the innermost. Gold Roman numeral appliqu_s mark the hours, above which are the Arabic numerals of the retrograde date dial. The Rose gold hands for hours and minutes boast delicate engraving while the date hand is sleek, providing intrigue and contrast for stunning legibility. The counterparts of the perpetual calendar are nestled in apertures to the 3, 9 and 12 o'clock positions, providing the Month, Day and Leap year counters. The moon phase subdial and tourbillon are found at the 6 o'clock position, completing the complications of the front dial. The pleasurable sound of the minute repeater is thanks to the two cathedral gongs activated by a slide piece in the case. The second dial provides sidereal time, a magical yet stunningly precise sky chart that mesmerizes while the phases and orbit of the moon are displayed beneath. The case of this timepiece is a complete work of art on its own, as the entire case is hand-carved and engraved from a massive blank canvas of white gold. All this and more has been done to stunningly house the R TO 27 QR SID LU CL caliber that ticks beneath these majestic dials. Special care should naturally be taken with this timepiece, but also as it is humidity and dust protected, not water resistant. This sublime watch is held to the wrist with a shiny blue alligator strap that has been hand-stitched and fastened by an engraved fold over clasp.
