The Steineck ABC is a subminiature camera made in the form of a wristwatch, produced in West Germany in the late 1940s. Worn on the wrist in place of a timepiece, it exposed small circular images on a disc of film and was sold as a novelty/concealable camera rather than a general-purpose photographic tool.

Auction data for the Steineck ABC wristwatch camera is thin: a single recorded UK saleroom result from 2002 saw an example hammer at £1,645, which gives an indication of what a complete piece has sold for at auction (wholesale level, before commissions) rather than a reliable current market median. With so few data points, today's value depends heavily on completeness, condition and whether the original case and instructions are present, and recent comparable hammer prices would be needed to confirm what one sells for now.
