The electronic circuit (1) controls the operation of the peripheral members of a watch. The circuit (1) includes a processor (2) connected to a non-volatile memory (3), which contains instructions to be carried out, peripheral member controllers (4) for interacting with peripheral members of the watch and connecting means (6a, 6b, 7). These connecting means (6a, 6b, 7) are arranged to enable the peripheral member controllers (4), the non-volatile memory and the processor (2) to communicate data relating to the operation of said watch to each other. This electronic circuit (1) further includes initializing means (8) able to act on the peripheral member controllers (4) to initialize said controllers so that they can execute operations independently of the processor (2) and/or the non-volatile memory (3).
