The legendary octagonal Octo case, testimony to the modernity Gérald Genta has brought to watchmaking, returns in a Tourbillon Sunray version. The two yellow gold plates making up the dial reveal a retrograde hour on a black lacquer ground, while an octagonal window highlights a beautifully constructed tourbillon. The final act of splendour in this dazzling composition, – a veritable ode to the sun –, is the manufactory-made movement, coated with old gold. This is the Gérald Genta signature, the “Potter finish”, so typical of vintage movements.
