Total newbie here, but what's the difference between the Purist and the other models?

N55_E82Adding to what @Cjbr89 said, the GMT ones (not the purists) also have an additional hand that does turn once per 24 hours (the small red arrow). This is called a GMT hand and is used to track a different timezone. Adding to that the rotating bezel making possible the tracking of an additional timezone, the GMT models can track a total of 3 different times, while the purists can track two. This is not to say that the GMT models are superior. It's just a different design.

N55_E82Yes you can, GMT is only an appellation here, referring to timezones in general.
The way it works is you set the time and date normally, then you set the GMT hand separately. While setting the GMT hand, it will jump in one hour increments and you can set it as an offset of your normal hour and minute hand time. Example : if you set your time to 14:30, you can move the red arrow three hours later to 17:30. You can also move it all around the dial and set it three hours earlier to 11:30. The numbers (1 to 24) on the inner ring on the dial will tell you what the red arrow points to.
N.B. : You can't set the GMT hand for half hour time zones (we have one of these in Canada). It only jumps in hour increments and you only have one minute hand anyway (or only one one-sided minute hand).
Now this model has an additional timezone that can be set. You'll see from photos that there's also an outer ring of numbers. This ring is on a rotating separate dial that rotates by operating the pusher at 2 O'clock. Offsetting this outer ring from the inner ring will make it that the red (GMT) hand points to two different hours. You therefore have a GMT hand that can denote two different timezones instead of just one.
You have to understand though that on the GMT models, there will be a bit of confusion about reading the "normal" time (normal hour and minutes hands). What I mean to say is that you have an inner ring of numbers for the GMT hand on the dial that are printed directly besides the hour markers (small rectangles showing the normal 12 hour scale). As @Cjbr89 explained, the "normal" (white) hour hand will make 2 rotations per 24 hours (or 1 per 12). You therefore have two conflicting scales one just beside the other. The hour markers should be (as everyone knows) denoting 1, 2, 3, 4, ..., 11, 12. However, the GMT inner ring that coincides with these markers will read 2, 4, 6, ..., 22, 24. You therefore have to ignore the inner ring while reading the normal time and only take it into account when reading the time of the GMT hand. Of course, you'll see that the GMT scale divided by two equals the "normal" hour scale. This is evident seeing that the GMT hand makes one rotation per 24 hours and the hour hand, two.
You can imagine the purist version as a GMT version where the hour hand is installed on the GMT hand (and the red GMT hand thrown away).
