Konstantin Chaykin’s White Rabbit prototype sold for a hammer price of CHF 420,000 at Ineichen Auctioneers in Zurich on 13 December 2025. Ineichen recorded 22 bids for Lot 6. The result is distinct from the November announcement of the sixth and final watch in a sold-out six-piece edition: the auction house identifies the lot as a prototype.
What did the Chaykin White Rabbit sell for?
Ineichen Auctioneers records a hammer price of CHF 420,000 and 22 bids for Lot 6 at its 13 December 2025 auction in Zurich. The auction record describes the lot as the White Rabbit prototype. Ineichen’s Lot 6 record
Konstantin Chaykin Manufacture’s post-sale report also gives the result as CHF 420,000 and states an equivalent of USD 529,200. That dollar figure is the maker’s reported equivalent, not a current exchange-rate conversion. Konstantin Chaykin Manufacture’s sale report
Was it the sixth and last White Rabbit?
The November 2025 announcement framed the White Rabbit as the sixth and final watch in a limited edition of six, and said the edition had sold out immediately. The later auction record and the maker’s post-sale account identify the item sold as a prototype. Those descriptions are related but not interchangeable: the announcement’s edition wording does not establish that the auction lot was the sixth numbered edition watch.

This is the maker’s account, not independent verification of all private sales. Monochrome Watches’ 20 November 2025 announcement · Konstantin Chaykin Manufacture’s sale report
What makes the White Rabbit unusual?
Inspired by Lewis Carroll’s Alice’s Adventures in Wonderland, the White Rabbit is a transformable “wristmon”: its double-sided case can be used as a wristwatch or converted into a pocket watch. The announcement connects the concept to Alice’s observation in chapter seven about a watch that shows the day of the month but not the time.

The announcement lists 16 complications, including Chaykin’s joker indication; a perpetual calendar showing date, day, month and leap year; day and night length; dead-beat seconds; moon phase; instantaneous AM/PM; sunrise and sunset; zodiac sign; and suspended time. The mix combines conventional calendar and astronomical indications with the maker’s more playful display. Monochrome Watches’ announcement and specifications
