Note: Like any technology DCF, the time change summer / winter is not done correctly if the signal has been received (and not on WINDOWS where by checking the checkbox time change summer / winter is systematic) .
So check at that time ... On this shows the signal is received when the logo (visible in the upper right) is enabled (from the early morning), so REASSURING !!
If, unfortunately, you break like me, the attachment of the strap (after 3 years in 2012) you will find the spare bracelet AMAZON under the name of Casio Bracelet Watch Stainless Steel WV-200de-1AVER ... Just over 20E, you be the judge ...
