Introducing our first collaboration with grailwatchofficial: The GRAIL WATCH 5: CHRONOSWISS OPUS BLUE. The world’s first serially produced automatic skeleton chronograph returns with a blue grade 5 titanium case and an arresting luminous signature. A modern, luminous riff on Chronoswiss’ historical game-changer, Grail Watch 5: Chronoswiss Opus Blue is the first limited edition collaboration between grailwatchofficial and Chronoswiss, and brings together the creativity of its two leaders, Wei Koh and Oliver Ebstein. Housed in a 41mm CVD-treated blue titanium case, Grail Watch 5: Chronoswiss Opus Blue brandishes a chromatic energy inspired by earlier Chronoswiss release. It is made in just 30 examples and priced at CHF 13,300, now available exclusively on GrailWatch.com #chronoswiss #chronograph #opus #grailwatch #limtededition #modernmechanical #chronoswissopus
