Ok, so this watch has analog and digital and GMT/World times. The analog and the digital can be set separately, even the minute hand (which seems odd).
The GMT is calculated off the digital setting. I have it set for NYC (eastern time) and DST on.
But the GMT shows 4 hrs ahead instead of 5 hrs (and UTC on time.gov confirms it to be 'slow').
