M for Mastery and Mechanism. #Master _ Master Ultra Thin Tourbillon Moon Designed, made and assembled in our Manufacture _ Bringing together a Tourbillon and a Moon phase, the Master Ultra Thin Tourbillon Moon is a demonstration of technical expertise while staying true to the elegant design codes of Master Ultra Thin. Set in the upper half of the dial, the astronomical complication displays the Northern Hemisphere moon phases in the traditional way and surrounding it, a ring displays Southern Hemisphere moon phases on the left and the Age of the Moon on the right. Placed between the 15th and the 16th, the jumping date leaves the Tourbillon fully visible while it completes its 60 seconds revolutions. _ #JaegerLeCoultre #Master
