To prevent any impairment of the good legibility of the dial, the tourbillon mechanism with the patented stop-seconds function is visible only from the caseback side of the "LANGE 1 TOURBILLON PERPETUAL CALENDAR". The relief-engraved tourbillon and intermediate wheel cocks frame the tourbillon ensemble that is composed of 69 individual parts. The large central rotor in 21-carat gold with a platinum centrifugal mass generates a fully-wound power reserve of 50 hours. Each of the three train bridges is embellished with solarisation. On the front the calendar displays with the patented peripheral month ring are harmoniously embedded in the dial. It delivers at-a-glance readings of the date, day of week, month, leap year and moon phases. All indications of the perpetual calendar - oversized date, retrograde weekday, month ring, leap year and moon phase indication - switch instantaneously and therefore always delivers a doubt-free reading.
