Louis Vuitton brings two prestigious complications – a minute repeater and a flying Tourbillon – inside a Voyager case, recognisable by its not-quite-round, not-exactly-square shape. Two versions are proposed: the sobriety of white gold with polished and satin finishes, or with the addition of eight carats of baguette diamonds on the bezel and lugs. Despite the complexity of the movement, which provides four days of power reserve, this is a remarkably thin watch – one of the slimmest in its category – at 9.7mm high. All eyes are on the mechanism, revealed in all its splendour through the sapphire crystal dial and caseback. Passing hours and minutes, completed by a V-shaped small seconds display on the tourbillon carriage, transform time into music, chimed on the minute repeater's cathedral gongs – a first for Louis Vuitton.
