The Louis Erard x Konstantin Chaykin Time Eater Tourbillon brings the saga of this strange horological beast to a thrilling new chapter. A fusion of fantastical design and serious Swiss watchmaking, this limited edition of just 78 pieces features the now-iconic cyclopean eye and sharp-toothed grin, joined this time by an animated red tongue spinning with every passing second. Chaykin’s latest trick? A mechanical tongue mounted on a tourbillon cage, bringing a surreal twist to a complication rarely seen in such playful form.

The 42mm polished stainless steel case houses a hand-wound tourbillon regulator movement, developed by BCP Tourbillons and boasting an impressive 100-hour power reserve. The dial delivers a dramatic mix of textures and tones, sunray silver, satin-finished anthracite, and a red tourbillon flange with a white fang motif. The hour disc at 12 o’clock keeps its single, all-seeing eye motif, while the black central minute hand splits into two monster-like tips. Every detail on the dial has been carefully placed to enhance both storytelling and timekeeping precision.

The Time Eater Tourbillon is completed with a black toad leather strap accented with green stitching and a soft rabbit leather lining. Its green minute ring and dual logo transfer, Louis Erard at 6 o'clock, Konstantin Chaykin at 12, mark it unmistakably as a collaboration between two visionary forces. With sapphire crystals front and back, a signature Chaykin crown, and 50 meters of water resistance, this tourbillon balances whimsy and technical mastery in equal measure. A rare collector’s piece that blurs the line between watchmaking and art.
