Pierre Laurent is making history again. Our new special edition Classic Chronograph Collection is made with authenticity, passion and purpose. The combined efforts of designer and watch maker have created the finest Swiss made quartz chronograph watch in history. It combines an oversized calendar with a day retro-grade seventh hand. Being accurate to 1/10th of a second, it still maintains a water resistancy of 100m using a screw down crown and sapphire crystal.
