The Last Laugh: Louis Erard & Konstantin Chaykin’s Time Eater Finale
The collaboration between Swiss watchmaker Louis Erard and Russian independent Konstantin Chaykin enters its final chapter with a more complex mechanical expression: the Time Eater Tourbillon. Known for combining traditional Swiss horology with whimsical, animated design, the Time Eater series now concludes with a statement piece that integrates a one-minute tourbillon into its expressive dial layout.

A Distinctive Take on Time Indication
Like its predecessors, the Time Eater Tourbillon embraces the regulator-style display—a format that separates the hours, minutes, and seconds onto different axes. Hours are shown via the now-iconic rotating eye, a signature drawn from Chaykin’s Wristmon series. The minutes are indicated by a central hand, while the seconds occupy the “mouth” at six o’clock. What sets this model apart is the tourbillon carriage integrated into the mouth, replacing the traditional seconds hand. The carriage doubles as a tongue-like indicator, continuing the playful theme while introducing a high complication into the display.

Case and Dimensions
The watch features a case crafted entirely in polished stainless steel, measuring 42 mm in diameter and 12.65 mm in thickness. These dimensions preserve the proportions of earlier Time Eater editions while allowing space for the added mechanics of the tourbillon. The case construction supports ergonomic wearability and maintains a bold visual presence on the wrist.

Limited Editions with Distinct Availability
Louis Erard is offering the Time Eater Tourbillon in two limited variants, each differentiated by their accent colors and distribution channels. The first version includes green accents and is limited to 78 pieces, distributed through Louis Erard’s network and official retailers. The second features blue accents and is limited to 28 pieces, sold exclusively through Konstantin Chaykin’s boutique in Moscow. Aside from the color scheme, both editions are identical in technical execution and design features.

Tourbillon Movement with High Autonomy
Inside the watch beats the BCP T02 calibre, a hand-wound movement developed by BCP Tourbillons, a Swiss manufacturer founded by movement engineer Olivier Mory. This movement is equipped with a 60-second tourbillon, visible through the opening at six o’clock, and delivers a substantial 100-hour power reserve. While industrial in character, the movement is competently finished and designed for robust performance. It is also widely used across accessible Swiss tourbillon timepieces, ensuring reliability and consistency in this price segment.

A Final Expression of Horological Playfulness
Bringing together mechanical complexity and creative design, the Louis Erard x Konstantin Chaykin Time Eater Tourbillon stands as a unique horological creation. Its expressive character, strong visual identity, and noteworthy complication make it a standout conclusion to the Time Eater series. Priced at CHF 19,900, the model offers a rare blend of avant-garde design and fine watchmaking in an accessible package, closing the collaborative series on a high note.
