A woman buys an old mechanical watch at a flea market and soon notices that it occasionally ticks backward for a few seconds. Each time it happens, small events around her subtly change — allowing her to avoid minor accidents or react to things just before they occur. As she tracks the phenomenon, she realizes the watch doesn’t truly reverse time, but briefly gives reality a chance to correct itself. One night the watch spins several minutes backward, warning her of a dangerous gas leak in her apartment. Later she discovers an engraving on the back: “Second Chances Only.” Eventually the watch stops working, leaving behind the unsettling idea that time itself may sometimes allow small corrections — but never forever.
