    Gulfmaster, Mudmaster, PRW-6000 minute hand, hour hand movement frequency

    My understanding is that the Gulfmaster, Mudmaster and PRW-6000 have separate motors for the hour hand and the minute hand.

    How often does the minute hand move on these watches?

    How often does the hour hand move?

    I'm just curious.

    I only have one watch that has separate motors for the hour hand and minute hand: the Citizen Promaster Sky BY0080-57E. On this watch, the minute hand and second hand are geared together, so each moves 60 times per minute. The hour hand and 24-hour hand are geared together, and each moves once every 2 minutes.

    The minute hand on my Gulfmaster and PRW6000 moves in 10 sec block movements.
    So it moves only 6 times per minute.

    Not sure about the hour hand though....

    If you look at the manual near the end in Specification - Analog Timekeeping, you will find confirmation that the Minute Hand moves every 10 seconds. But, they didn't say anything about the Hour Hand! I don't own any of the 3 watches you mentioned, so I can't tell you any better. But it wouldn't surprise me that the Hour Hand only update every few minutes, since Casio's designs are more gear toward power saving.

    Hour hand moves every two minutes, the minute hand moves every 10 seconds. Doing the math you'll find that both hands make 360 steps to complete one full turn. So one step equals 1 degree.
