Basel World 2010- One of the truly hot watches at Basel World this spring is the new Patek Philippe Nautilus reference 5726A. Incorporating the Caliber 324 S QA LU 24H movement, this new Nautilus model features an Annual Calendar. It comes in a stainless steel case and is worn on a hand stitched alligator strap with a fold-over clasp. The watch's dial is black and comes with gold applied hour markers. The case size is a contemporary 40.5mm in diameter. Patek Philippe has combined two very popular themes: the Nautilus and the Annual Calendar.
