On the older Eco-Drive World Time watches (Calibre C605), the analog and digital portions of the watch work independently and are not synced like the newer Skyhawks. If the analog has stopped and the digital display is dim, it may be a capacitor problem. However, if the digital display is bright and the analog has stopped, it is likely a mechanical problem. We can repair this problem, but it is typically twice as expensive as a capacitor replacement.
