What it is
The 905x family is Citizen’s mid-range automatic, found in the Promaster Fujitsubo and the sportier Series 8 models. It beats at 28,800 per hour, so the seconds hand steps eight times a second, and gives about 42 hours of reserve.
The 9051 shows the date; the 9054 adds a GMT hand to read a second time zone. Both hack and hand-wind.
For anyone who wants the high beat rate of a classic Swiss movement in a Japanese watch.
Maker: Citizen. The figures on this page come from each watch’s spec sheet.
