Girard-Perregaux has decided to keep the party going for the 50th anniversary of its sporty Laureato. The watchmaker just unveiled four new references within its Laureato Fifty lineup, after debuting a limited-edition timepiece late last year to ring in that 50-year milestone. And this quartet, now permanent members of the Girard-Perregaux family, remains true to the spirit of the Laureato, with a ‘70s-inspired octagonal bezel, tonneau-shaped case, and an integrated bracelet—with a few modern tricks up its sleeve, of course. One of those is the movement. The Girard-Perregaux in-house Calibre GP4800 found here—one of three new movements unveiled by the brand since last September, in a horological flex—is home to 10 different finishes, including sandblasting, sunray finishing, circular satin-brushing, and more. The self-winding mechanical movement is also equipped with an 18-karat pink-gold oscillating weight and balance bridge—done up in the material specifically for this collection.
