Title:
DEVICE AND METHOD FOR TESTING THE LEAK-TIGHTNESS OF A TIMEPIECE CASE
Document Type and Number:
WIPO Patent Application WO2004019141
Kind Code:
A8
Abstract:
The invention relates to a device for testing the leak-tightness of a case (2) belonging to an electronic timepiece (1) comprising a time base (42) which is used to produce a standard frequency signal and a central processing unit (44) which is used to determine the time from said standard signal. The invention is characterised in that it comprises an electronic sensor (32) which can measure fluctuations in the concentration of an atmospheric gas confined in the case (2). According to the invention, the results of the measurement taken by the electronic sensor (32) are processed by the central processing unit (44) which, if necessary, emits an audible or visible alarm in response to the measurement signal.
