Trained by the brilliant Abraham-Louis Perrelet, Perrelet Louis-Frederic went on to become the official watchmaker to the French Court. Following in the revered footstep of his grandfather, he carved a name for himself in the same field and is credited for inventing the split-second chronograph mechanism. Today, this unrivaled know-how is evident in the Perrelet Louis-Frederic''s power reserve and chronograph Rattrapante models. Constructed from titanium, steel or 18k rose and white gold, the collection exhibits a sporty appeal with its rubber strap and dial design. An anti-reflective sapphire crystal secures the hours, minutes, seconds, and calendar display and also reveals the automatic movement through the exhibition caseback. Measuring 42mm to 44mm, the Perrelet Louis-Frederic timepiece packs a power reserve of 46hrs and is tested water resistance up to 50m.
