The refined G.F.J. revives the iconic caliber 135, renowned as the most celebrated movement from the golden era of observatory chronometer contests. Expertly redesigned with subtle enhancements, it boosts reliability, accuracy, and performance while preserving its original character. Encased in a sleek 39mm platinum round case with a stepped bezel and elegantly curved lugs, it showcases a three-part blue dial featuring brick guilloche, lapis lazuli, and mother-of-pearl. This timepiece comes with three versatile straps: dark blue alligator leather, black calfskin leather, and blue “Saffiano” calfskin leather.
