Abstract
When using wristwatches for diving or action sports, it is desirable to be able to prevent the winding button from being pulled out inadvertently and the time unintentionally altered. To avoid this, the button (3) has the overall shape of an H and a lever (2) engages in the groove (10) in said button (3) to prevent this button from being pulled out in error.

- an external groove extending around the periphery of the winding button;
- and
- a lever pivotally mounted externally on the watchcase between a locking position in which the lever engages the peripheral groove of the winding button to lock said winding button in its winding position, and a disengaged position in which the lever is free from said peripheral groove to allow the winding button to be moved between its winding position and pulled-out position.
