A watch equipped with a striking mechanism that can be activated at will, striking on the hours and fractions of hours. Breguet’s repeating watches usually repeated the quarters and half-quarters, with some highly prestigious versions repeating the minutes. The striking mechanism was set in motion by a retractable push-piece (like a sliding piston) concealed in the watch pendant. Becoming widespread from 1800, the system was elegant and reliable; it could also be placed on the caseband. In certain repeating watches, known as dumb repeatings (à toc), the hammer strikes the case directly (instead of the gong-spring).
