The Louis Erard Regulator Monster is back, known as Time Eater III as a final bite, a collaboration with Konstantin Chaykin.

Two years ago, Louis Erard & Konstantin Chaykin unleashed their first beast. A one-eyed freak straight out of Slavic legends: half myth, half joker, full madness. It was nicknamed the Time Eater. It stared at you. It made every second that counts fun. It sold out faster than you could blink. Today, it returns, hungrier than ever. Two Regulator versions… you asked for them and we simply couldn’t resist! And for the first time ever, this legendary collab will be sold by both Louis Erard and Konstantin Chaykin.

Time Eater III Facts:
- Two collectible watches: Pick your monster! One sold by Louis Erard, one by Konstantin Chaykin
- The mono-eye: Convex. White with a black pupil. Alive. Always watching. It’s the hours disk, set inside the 12 o’clock counter
- The rebellious hand: A central minutes hand that doesn’t follow the rules. One end raises a defiant finger, the other flashes a rock’n’roll salute
- The toothed mouth: A sharp-toothed spinning disk set in the 6 o’clock counter
- The face: A colored minutes ring with the Louis Erard logo at 6 o’clock and Konstantin Chaykin’s name at 12 o’clock. Red for Chaykin, blue for Louis Erard
- The crown: signed by Chaykin, because every WristMonster needs the mark of its maker

Manuel Emch, CEO, Louis Erard
“This time, it was Konstantin who called, with a grin of course! He said: “Making watches together is fun, but wouldn’t it be even better if I could actually sell a few?” Classic Chaykin: part mischief, part mastermind… but with that call…that grin… there was something more… a sense of ‘stay tuned’! So two years after the original Cyclops, part Slavic myth, part horological joker, we return with a new sequel. Two new editions of the Regulator: red or blue, as for the first time, the monster is being sold by both of us, meaning there’s no need to pick a side, just a color! The story doesn’t stop here. This isn’t goodbye. The monster evolves. The collaboration continues. What’s next? It’s already lurking out there ready to appear. You have been warned!”

One mouth, one eye, two hands that don’t play by the rules. The iconic Louis Erard x Chaykin collab returns with its Regulator face in a double 178-piece edition with two new colourways:
- A blue minutes ring 42mm edition, with a toad leather strap, sold by Louis Erard.
- A red minutes ring 39mm edition, with a grained calfskin strap, sold by Chaykin.
Both share the same expressive dial blending the signature vertical Louis Erard Regulator display and Chaykin’s unmistakable WristMonster face. The mechanical self-winding regulator features a hypnotic mono-eye hours disk at 12 o’clock, a rotating toothed mouth for small second at 6 o’clock and a rebellious central minutes hand. Just 2 x 178 and that’s it. Once gone, gone for good. That’s what we call the final bite of the Regulator.
