Some years ago I became very familiar with this watch using the same bifrequence concept. Amazing how the same principle can be applied to completely opposite outcomes; greater precision in the case of one and greater power economy for the other.
The fun about watches u know, is the variation in peaces. Wear different watches, even a grail is sometimes not enough to stop loving other wathes.
It surprise me a humble peace can blown an exclusive watch away. So for the others who dream of that grail who is unreachable, there are watches out there who can do the same love as the thing.
So owning a grail and the man discovered he wear his Swatch more than his Cartier Tank, than he is a tru WIS.
