In a limited edition of 178 pieces comes the new Louis Erard x Konstantin Chaykin Le Régulateur ‘Dusk to Dawn’. Two watches in two different sizes and with two different case finishes. Inspired by the grotesque saw-mouthed cyclopes by the Slavic Likho legend. The watches can be purchased in a quadriptych box that includes four watches —the two previous iterations of this model and the new ones— or in a diptych box that includes both new watches.
