Watch with tactile zones of capacitive type comprising a battery hatch closed by an electrically conducting cover

摘要

A wristwatch with capacitive touch zones including a case made of a non electrically conductive material, the case including a housing in which a battery is housed and which is closed by an electrically conductive battery cover. The electrically conductive battery cover is mounted on the watch case with interposition of an electrically conductive sealing gasket between the battery cover and the battery.

1. A wristwatch comprising:
capacitive touch zones; and a case made of a non-electrically conductive material, wherein the case includes a housing in which a battery is housed and which is closed by an electrically conductive battery cover, wherein the electrically conductive battery cover is mounted on the watch case with interposition of an electrically conductive sealing gasket between the electrically conductive battery cover and one of terminals of the battery, and the electrically conductive battery cover is configured to be in contact with a user's wrist skin, so that a body of the user, the electrically conductive battery cover, the sealing gasket, the battery, and the capacitive touch zones are at a same electrical potential during detection of a capacitive variation of the capacitive touch zones.
