Girard-Perregaux recently announced a new limited edition of its bi-axial Tourbillon with a black DLC-coated titanium case. The watch features two concentric cages making multidimensional rotations: an internal cage containing the balance wheel, balance spring and escapement, completing one full turn on its axis every 45 seconds, and an external cage rotating on a second axis, completing a full turn every minute and fifteen seconds. Despite containing more than 110 components, the two cage mechanisms have a combined weight of only .8 grams

I’ve been a reader of you fine magazine for a few years now, trying to increase my knowledge of horology. However, during this time, I haven’t seen much on how one might detect a counterfeit watch. There is a huge criminal element that is producing counterfeit watches at an alarming rate. There are some obvious giveaways to some of the lesser reproductions, but I’d like to see an in depth article on some of the more complicated counterfeits.
