L.U.C 150 "all in one"
Chronometer-certified by the COSC and bearing the prestigious Poinçon de Genève quality hallmark, the L.U.C 4TQE movement houses four barrels endowing it with a seven-day power reserve. It powers displays of the hours, minutes, small seconds on the tourbillon, a perpetual calendar showing a 24-hour indication, the day of the week, the date through a window, the month, the leap year, the power reserve, along with a 24-hour indication, the equation of time, sunrise and sunset times and moon phases. Comprising 516 parts and 42 jewels, the L.U.C 4TQE movement beats at a frequency of 28,800 vibrations/hour.
The 46 mm-diameter case of the L.U.C 150 “all in one” is crafted in white gold and water-resistant to 30 metres. It adopts the new style of the L.U.C complication models unveiled for the brand's 150th anniversary.
Vertical satin-brushed finishes and lugs with polished tops are part of this renewal, as are the newly shaped hands, the new fonts and the redesigned Roman numerals enhancing the dial.
The multiple indications and complications of this perpetual calendar, equation of time and tourbillon watch are displayed on the gold guilloché-worked upper dial, as well as on the second dial on the case-back side.
In addition to the hours, minutes and small seconds on the tourbillon at 6 o'clock, the upper dial displays the perpetual calendar with 24-hour indication and the day of the week at 9 o'clock, the large date window at 12 o'clock, along with the month and the leap year at 3 o'clock.
The equally guilloché-worked gold plate of the dial on the case-back bears the equation of time, power reserve, 24-hour day/night indication, sunrise and sunset times, as well as the astronomical orbital moon-phase display depicting the dance of the heavenly bodies – set to coincide with Geneva – and its mechanical expression.
