The red bar turning inside the tourbillon cage is the running seconds. It is also the tongue. Louis Erard put the blue Time Eater Tourbillon on its own store on 10 August at CHF 19,900, twenty-eight pieces.

Konstantin Chaykin has spent years building watches with faces that stare back at you, and this is the one that chews. Up at twelve there's an eye: a black-ringed disc with a white dome and a single dark pupil that drifts round as the hours pass. Down at six, a red mouth, drawn with teeth.

Hours in the eye, minutes on a limb

Underneath the gag it's a regulator, which is what stops the layout from just looking busy. Hours come off that rotating disc at twelve, read against 12, 3, 6 and 9 on the black ring. Minutes live out on the chapter ring, blue with white dots, swept by a long matt black hand with a blob at one end and a two-pronged claw at the other. Louis Erard calls those the monster-hand tips, and they're why the minute hand reads as a limb rather than a hand.

Louis Erard's own copy describes the tourbillon as "a mechanical tongue that spins", which is a tidy way of saying the complication and the joke are the same part. Between the eye and the mouth, the silver plate is engine-turned with a sunray wave, so the whole face sits on moving water.

The blue one's spec block still says green

There's a bug in the specifications. Louis Erard's block for the blue model calls the minute ring shiny green, and it is blue, in the brand's own photograph and in the name of the watch. The whole paragraph has been lifted word for word from the original green Time Eater Tourbillon, green stitching included. Someone duplicated the page and left it there.

A hundred hours out of one barrel

The calibre is the BCP T02, hand-wound, a tourbillon regulator with hours, minutes and seconds, and Louis Erard rates the reserve at roughly 100 hours. Four days from a single barrel with a tourbillon on the end of the train taking its cut the whole time is worth some credit.

The case is polished steel, 42mm, with a display back and sapphire treated for reflections on both sides. Water resistance is 5 bar. The strap is black toad leather on a steel pin buckle, with quick-release spring bars, so swapping it takes no tools.

The tourbillon adds CHF 15,450

The Régulateur Time Eater III, the same watch without the tourbillon, is CHF 4,450 on the same store. Whether a spinning tongue is worth the difference has one obvious answer for twenty-eight people and a different obvious answer for everyone else.

The first Time Eater Tourbillon went up in June 2025 at the same CHF 19,900 and is still listed. There's no Australian price, because Louis Erard sells in francs from its own site.
