Official description

Louis Erard delivers his regulator as a sacrifice to a very strange creature: a grotesque saw-mouthed cyclops. A mythological figure reinterpreted by the master watchmaker Konstantin Chaykin. Two colour variations, in limited editions (twice 178 pieces) and in a diptych (box set limited to 28 pieces).

Louis Erard x Konstantin Chaykin. Two door openers. Louis Erard, maker of beautiful and accessible Swiss made watches, has become a mentor for cross-disciplinary collaborations under the direction of Manuel Emch, with métiers d’art (guillochage, marquetry, enamel), with creators (seconde/seconde, atelier oï, Label Noir, Massena Lab) and with the great names of independent watchmaking (Alain Silberstein, Vianney Halter) - and others to come.

Konstantin Chaykin is a member of the AHCI (Académie Horlogère des Créateurs Indépendants) with a worldwide reputation and proven inventiveness (94 patents). The master watchmaker has also earned a reputation in the very special world of watches with faces. Faces of monsters. The collection is called Wristmons (wrist monsters), it was launched in 2017 and has been expanding every year since, like a big family of happy villains.
