The Zentra 78 watch movement is a mechanical movement that was used around 1945. It belongs to a series of movements (285, 287, 288, 292) that have different pillar plate sizes. The 288 movement incorporates a Breguet hairspring and features a manual-wind chronograph function with a 60-second measurement capability and secondary sub-dial. Additionally, it includes a pillar wheel mechanism and gives the option of a 12-hour chronograph display, similar to the 285 model.
