IRO is a small independent watch house built around a single idea: hiding a stereogram in the dial of a watch. Its founder describes having been fascinated by mysteries and secrets since childhood and being well acquainted with stereograms and their possibilities, and set out to combine a material that carries millennia of mysticism — mammoth ivory — with the possibility of magical visions offered by the stereogram and the primary object that records the flow of the universe, the clock. The result is a dial on which an interested and determined viewer can find the infinity symbol, breathing mysterious life into an ordinary object.

The house works to commission, and at a customer's request can depict any symbol using a stereogram. The company consists of three people, and the name IRO means permanently. The founder also notes that looking at and finding stereograms trains the eye and has a healing effect.
