New from famous French fashion house Chanel comes a one-of-a-kind version of their J12 Marine watch updated in an elegant black colorway for the ONLY WATCH charity auction. Taking design cues from a slew of legendary horological inspirations, the watch is a fully functional diver, equipped with Swiss automatic movement and capable of delving up to 300 meters before succumbing to the pressure of the deep. The true beauty of this piece, however, is its luxurious styling. Complete with a sand-blasted blacked-out ceramic case, sapphire crystal, sporty rubber band and 18kt rose gold detailing, this 38mm watch is surely a statement piece. Somehow we doubt you’d use it much for diving.
