The Girard-Perregaux ww.tc Shadow is a technically captivating, stylish world time chronograph watch, which employs cutting-edge materials in its construction.  Measuring 43mm in diameter, the case of this Girard-Perregaux timepiece is made from hypoallergenic black ceramic, formulated from a mixture of zirconium oxide and polymer.  Just slightly heavier than titanium, and much harder than steel, the ceramic material in the ww.tc Shadow's case is the result of a meticulous manufacturing process, which involves several firing stages to insure optimal hardness and a lack of porosity flaws.  

A black dial with red accents compliments the sporty aesthetic concept of the Girard-Perregaux ww.tc Shadow.  The rotating world time disc posits cities of the world in white against a black background, while the inner rotating day/night indicator provides clear differentiation of AM and PM times.  Bold luminous hands and hour markers keep legibility high regardless of the amount of ambient light.  

The Girard-Perregaux ww.tc Shadow watch is animated by the self-winding GP03387 caliber.  Conceived and produced by Girard-Perregaux, this finely decorated movement offers a chronograph complication with a flyback function, in addition to the innovative and useful world time complication with day/night indication; a rapidly adjustable date display is another useful function.  Balance frequency of the GP03387 caliber is 28,800 beats per hour, and power reserve is 46 hours.  A sapphire exhibition window in the screw-secured caseback gives a fascinating glimpse of the movement's fine workmanship, which includes Cotes de Geneve patterns on the bridges.

The Girard-Perregaux ww.tc Shadow watch features a curved sapphire crystal, and a matte calfskin strap with a deployant buckle.  Water resistance is rated for 30 meters.
