This is a Patek Philippe Grand Complications replica watch. Replica meaning it is the Asian version replica. Automatic movement self winding. Does not need a battery. Like New. Worn only about 5 times. Comes with real crockodile wrist band. That is you can have the option of putting the black crock band and wearing it like that, or wear it with the metal band. The metal band is attached to it now, and it comes with the extra band that is real black crockodile I had custom made for it. One of several watches I fell in love with through the past few years on trips abroad. Now I decided to sell them. It's a real nice looking watch. You can see the internal movement moving from the back glass see through. Comes with a black protective zipper pouch.
