Which 1923 Man Ray artwork is a metronome with a photograph of an eye attached to it?

Man Ray’s 1923 artwork Object to Be Destroyed is a metronome with a photograph of an eye attached to its swinging arm.

Man Ray originally made the object as a personal work, placing an eye on a metronome so that the repeated movement suggested obsessive watching. The title invited destruction, and an early version was reportedly destroyed by a visitor at an exhibition. Man Ray then created later versions, changing the title over time, including Indestructible Object.

The work is often discussed alongside Surrealist ideas about chance, desire and irrational associations. Its exact title can cause confusion because different versions and editions have different names. The familiar title Indestructible Object does not describe the first 1923 conception; Object to Be Destroyed is the canonical title attached to the original idea. The work is also sometimes incorrectly identified as a photograph, although the photograph of the eye is only one component of the assembled object.
