Girard Perregaux Neo-Tourbillon with Three Bridges in Skeletonised, PVD-Coated Titanium - the bridges are secured on each side to the base plate which is gently inclined towards the middle, giving the movement a sense of depth and framing the movement which runs down the centre of the watch. Coated in ruthenium and frosted, the base plate is a dark grey, which contrasts with the black bridges. The tourbillon cage is a large 14.44 mm wide. It is made of titanium, giving the entire tourbillon a weight of just 0.25 g. Running at 3 Hz or 21,600 bph, the GP09400 movement is self-winding. Unlike earlier automatic versions of the tourbillon, the Neo Tourbillon has the micro-rotor under the barrel at 12 o'clock, instead of around it. A larger barrel and longer mainspring gives this a 72 hour power reserve. | by @thewatchestv | #GirardPerregaux #NeoTourbillon #SwissWatches (at Hamburg, Germany)
