These watches sit somewhere between the confusing displays of Tokyo Flash digital watches and the amazing mechanical-digital Meccanica DG. Inside they have two wheels that spin relative to a marker line: and that's where you peek to work out how many hours and minutes of the work day remain (that's the main reason for wearing a watch, yes?). It's all a bit 1970s tech, and rather cool. Available now for about $70. [BBGadgets]
