Tourbograph sounds almost wilfully cool — and it has a meaning to it too, as it refers to the combination of a Tourbillon regulating organ (the timekeeping heart of the watch) and a chronograph (i.e. a stopwatch). Perpetual stands for a perpetual calendar, the most complex Gregorian date complication inside a wristwatch that keeps track of the length variations between 30 and 31-day months as well as the varying length of February in normal and leap years alike. In other words, a watch with a perpetual calendar never needs adjustment — unless its wearer neglected to wear their beautiful timepiece and its power reserve ran out.
A large aperture over the 6 o’clock position reveals an extensively finished bridge that secures the tourbillon from above, while the trademark-style organ oscillates and pulsates underneath. Even the dial itself is in solid Honeygold — a special alloy of gold with outstanding sheen and colour —, with its texts and numerals raised from the grey rhodium-finished surface.
The price for the A. Lange & Söhne Tourbograph Perpetual Honeygold is €500,000.
