The watch still uses the the hand-finished L082.1 automatic movement and the tourbillon is visible through the sapphire crystal case back. It is claimed that the perpetual calendar mechanism is designed so that it only needs to be advanced by one day in the year 2100. The moon phase (displayed in the subsidiary dial at 7 o’clock) will only need to be advanced in 122.6 years, which is damn impressive if you ask me. The dial displays the (retrograde) day, month, hour and minute, oversized date, constant seconds, and moon phase. It very much looks like a normal Lange 1, though it’s anything but.
