I bought a Carrera Calibre 5 in November from Amazon. The watch works fine, but the hands don't stay illuminated for more than 10 minutes. The watch could not have been manufactured more than a year ago because this watch debuted less than a year ago. Has anyone else had this issue? Is there something I'm doing wrong? I wear the watch daily, surely that should be sufficient to charge the luminous hands? Any recommendations or advice would be appreciated.
