Questions answered in these manuals
What does the second hand jumping every 2 seconds mean?
It indicates the battery power is very low (level 2). The watch must be exposed to light to recharge before it can receive time‑signal updates.
What should I do if the watch does not receive a time‑signal?
Check that the watch is placed in a bright location, away from metal objects, and try manual reception by holding A for two seconds, then follow the on‑screen prompts.
