GP 3 sapphire bridge tourbillon...
Is the entire movement for the 3 sapphire bridge tourbillon manufactured in the GP factory, including the sapphire bridges. Or has some of it been manufactured else where? This piece is a real beauty!
Best,
Mike
sapphire bridges

I am not sure but i would guess that the sapphire bridges are made by aspecialized supplier. I reckon that cutting sapphire glass dos not belong to the traditional watchmaking techniques. Could anybody else provide us with more insight? regards, Stefan
