Only Watch: Akrivia Rexhep Rexhepi Chronomètre Contemporain II
What can one infer from a drawing of a new timepiece? As it turns out, a fair bit. The below sketch is the only bit of information revealed by Akrivia for its contribution to Only Watch 2021, the Rexhep Rexhepi Chronomètre Contemporain II (RRCCII). Despite the paucity of information, much can still be deduced from the single image. Initial impressions The most apparent fact that can be gleaned the sketch is a deadbeat seconds – a seconds hand that jumps discretely once a second. We can infer this from the star and flirt mechanism. The star is mounted on the escape wheel, which is located at six o’clock and completes a revolution once every five seconds. The star blocks the rotation of a flirt, a long lever that presses against the face of the star’s teeth. After each second, the star rotates far enough that the tooth provides enough clearance to release the flirt, allowing the star to rotate until the flirt contacts the next tooth of the star. This sudden release of the flirt is what controls the burst of rotational energy that drives the deadbeat second geartrain. Further inferences can be made from our May 2020 chat with Rexhep, where he hinted the RRCCII will have twin barrels powering separate going trains. In retrospect, that now makes sense in the context of the deadbeat seconds. One barrel drives the going train for timekeeping, including the escape wheel and the star. The other barrel drives a secondary gear train for the deadbeat seconds hand and the flirt...
