Joker – 20.000 grimaces of high watchmaking art

Watch with a classical dial is truly impressive just for few times a day. Every watch with hands in dial modestly laughs at 10:10 and 13:50, and expresses moderate sadness at 15:40 and 20:20. New ‘Joker’ watch, presented
by Konstantin Chaykin in BaselWorld-2017, is fitted with disk hours and minutes indicators as well as moon-
phase display.

New ‘Joker’ obviously has non-poker face because it is highly emotional and unpredictable – every minute. We counted that human eye will easily recognize more than twenty thousands of various grimaces, from hopelessly moody at full-moon 15:42 to flamy tongue-in-cheek at first quarter of the moon 15:48. Isn’t it amazing that Joker’s mood is manipulated by our nearest space neighbor more than any other creature? Nevertheless, most of the time Joker exhibits devil-may-care feeling, so you just want to say him “Gimme Five!”, as ‘Five of a Kind’ highest poker hand is engraved on the bezel of the watch case. ‘Five of a Kind’ is the highest poker hand, that is impossible to beat, and regarded as the sign of incredible luck.

Specially for ‘Joker’ watch Konstantin Chaykin had developed module with double-disk time indication (hours and minutes as Joker eyes) and moon-phase display (Joker’s recognizable smile). Module has 8 jewels for friction reduction, it is mounted on tried and tested ‘workhorse’ automatic winding Caliber ETA 2824-2. Additional fixed crown set in 9-o’clock position is fitted with recessed corrector provided for correcting the moon-phase display. The new ‘Joker’ watch is available in a stainless steel, the edition is limited to 99 pieces.
