Histoire de Tourbillon 2

In 2009 Harry Winston launched Histoire de Tourbillon collection. This year, for its second edition, the House launches an exclusive new timepiece with a bi-axial flying tourbillon in a 20-piece limited series. The monumental case features eight sapphire crystals housed in a 48.5mm white gold structure. The tourbillon has no upper bridge and is supported only from the side of the case such that the point of fixation is invisible, creating a floating effect. Look for wallpaper inside.

The the bi-axial flying tourbillon combines two concentric carriages – the outer formed from titanium – and gains added precision by enabling the regulating organ to perform multidimensional rotations. The striking visual effect is created by an outer carriage completing one full turn in 120 seconds and housing an internal carriage – holding the balance, balance-spring and escapement – that revolves in just 40 seconds.

The case effectively compartmentalizes the timekeeping functions. From the tourbillon coupled with running seconds at 9 o’clock, to the hours with day/night indication at 2 o’clock and the minutes at 6 o’clock, all the displays are isolated in independent offset subdials. The design creates a deeply multi-layered effect. Further enhancing readability, the day/night indications can be told apart by their color: orange for day, and blue for night.
