The intense blue sheen of the ultra-thin Patek Philippe Calatrava watch is due to the beautiful guilloché pattern that ripples across its surface. The deep blue dial contrasts beautifully with the powdered gold hour markers and the 33mm white gold case. For added contrast and sparkle, the bezel is encrusted with 48 baguette-cut diamonds, and the matching night blue, brushed satin strap with a prong buckle is set with another six diamonds. The Patek Philippe Calatrava watch is powered by a calibre 215 mechanical manually wound movement, which can be viewed through the sapphire crystal caseback, and has a 44-hour power reserve. The alluring deep blue tones and the beautiful guilloché pattern imbue this timepiece with sophisticated elegance and timeless appeal, which one always associates with Patek Philippe watches.
