Histoire de Tourbillon 8 square

Harry Winston gives another demonstration of what a high-flying watch mechanism can be with this Histoire de Tourbillon 8. The outer carriage of the two inclined double tourbillons makes one rotation in 75 seconds while the inner carriage rotates once in 45 seconds. A spherical differential connects the two. The time display takes the form of two conical aluminium discs, positioned on the right side of the dial-plate with its thirteen components. Power reserve is read from a grooved roller at 6 o'clock. The case in white gold contains a movement made almost entirely from titanium, a lightweight material prized for its anti-magnetic properties. The end result is a perfectly symmetrical design, with the mesmerising moving tourbillons mirrored by the hour and minute discs.
