Duomètre Sphérotourbillon Moon

Jaeger-LeCoultre 2015

ref. Q608 65 20
Men's

Operating on the Dual-Wing principle inherent to the entire Duomètre collection, meaning two independent mechanisms sharing the same regulating organ, this creation harmoniously combines the precisely adjustable Sphérotourbillon unveiled in 2012 with a dreamily beautiful moon-phase display. While a classic moon phase accrues a one-day deviation every two and a half years, and a so-called precision moon phase one day in 122 years, this one is designed to remain accurate for 3,887 years! Its lapis lazuli disc rotates beneath a finely grained silver-toned dial, directly opposite the tourbillon that is visible through the front, back and side of this remarkably elegant 42 mm-diameter platinum watch.
