The Timepiece

The 2010 Grande Complication is JLC's astronomical masterpiece in white gold: a minute repeater and flying tourbillon sharing the case with a celestial sky chart, zodiac calendar, and sidereal time — all under a matte blue constellation dial. The manual calibre 945 runs 40 hours at 28,800 vph. Seventy-five pieces. When collectors talk about JLC's golden age of grand complications, this is the watch they mean.
