This is often referred to as GMT in the dealer websites, which is wrong, the GMT is a different model and dealt with below. As you can see the sub dials on the World are in the 6, 9 and 12 configuration which is standard for the 7750 movement so the issue of moving the sub dial at 12 is not present. The gen with the GMT complication uses the B24 movement which is based on the Valjoux 7754, this is basically a 7750 with a GMT complication. Size of this watch is 46mm by 15.6mm in gen form, reps are accurate on this.
There are basically 2 rep options for the World, one made by BP and a version made by JF. Both versions come in black, silver/white and blue dials. The BP blue dial is less accurate than the JF blue dial, as it has a slight green tinge, however, in all other aspects the BP version wins hands down and is the best Navi rep available in terms of accuracy and in black dial form is verging super rep. You can spot the JF version easily because the slide rule does not line up with the dial, the datewheel is more sunken and the font is wrong.
On the JF caseback MOSCOW is spelled MDSCUW and NEW YORK is spelled NEW YDRK and O is missing from the end of RIO.JANEIR. Also missing is the serial number between Noumea and Midway. BP is correct. Not much else to say really, its pretty clear cut.
