- It lists WWVB, MSF, DCF77 and JJY, and reports one Casio Lineage synced on all four.
Field notes
The instructions connect a browser workflow to the watch’s manual-receive mode, which users may need to find in the watch manual. The page says most watches finish in two to four minutes and suggests switching to another method if no sync arrives after five; compatibility beyond its named Casio test is presented as expected rather than confirmed.
