    GMT/Dual time "Quick Set" movements?

    I was recently considering the purchase of a Concord Impressario GMT which utilizes the Zenith 682 movement.

    As I understand it there are two types of GMT "Quick Set" movements which can change time on an hour hand with the watch still running.

    The first type is the Rolex design in which the quick-set jumps the 12hr hand in 1 hour increments. For travelers it seems more efficient to keep home time on the 24 hour hand and use the quick-set 12 hour for local time.

    The second type has the quick-set jump the 24 hr. hand in 1 hour increments. This style seems to work well if one has to keep track of another time zone as to do business with an office in another time zone.

    The Concord is of the second type and I am interested in the first type. Maybe someday a Rolex will be possible but in the meantime what other makers utilize the Rolex type quick-set that moves the 12 hour hand in 1 step increments, while allowing the watch to keep running?


    thanks,

    Rob

    I believe Grand Seiko's GMT advances the 12h.

    Most you find will be ETA2893 based that advance the 24h hand.

    Panerai in house movt advance the main hour hand as I tried on their 12 hrs gmt,I've never had a chance to try their newer 24 hrs GMT though

    Another complication that I know uses JLC movt in which the main hour hand and 24 hrs hand are attached,but the watch has rotating inner bezel as shown in Pam 184/185

    The Omega 85xx hour hand moves in one hr increments without hacking the seconds. Not sure about their gmt variants.

    Seiko's Sportura line does as well.

    Yes; both of my Seikos are GMT watches, and both allow me to move the hour hand (without moving the minute hand) while the movement is running

    Any Breitling with a B04 (GMT) or B05 (world time) movement allows the hour hand to be set independently.

    I was just looking at the Seiko webpage for the High Beat GMT and found this quote...

    "Like almost all "true" GMT watches, the SBGJ005 doesn't quickset, the date is changed backwards and forwards by moving the independent hour hand."

    What does this mean, that the hour hand does not "jump" a single hour and it must be turned all the way around? How does one make sure it's registered properly?

    EDIT I found a Youtube video showing how to set a Rolex GMT and I see how the hour and adjusts around the dial. It did not however show if you can turn the hour hand backwards to set a different time instead of going all the way around and changing the date, can it be done?


    thanks,

    Rob

    I think they are referencing "quickset date". To rotate through dates on a Seiko or Rolex GMT you have to jump the hour hand 24 times to rotate through each date.
