I just purchased the Noob factory GMT II from a TD on this site. Setting the watch is a little complicated due to the custom A3186 / A3187 movement in the watch, so I thought I'd share my findings in a tutorial to help other members.
CROWN POSITIONS:
Position 0 = Crown screwed in
?
Position 1 = crown unscrewed.
?
Position 2 = hour hand adjust, resulting in the date changing when cycled 24 hours.
?
Position 3 (crown full out) = time adjust, including minute hand, hour hand, and GMT hand.
RULES / NOTES:
It seems the main rules to be aware of, are:
- Never adjust the hour/date hand in position 2, whilst GMT hand is between 10:00 - 02:20. This will break the movement apparently.
- Apparently never adjust any of the hands using a clockwise direction on the crown if possible (I found this impractical when setting the minute hand, and mine has not broken).
- I also noticed that moving my crown anti-clockwise changes the the time forwards, which seems to be the opposite to the gen, in which it would adjust the time forwards. So in short, the crown movement seems to adjust things backwards... A little bit strange, but none the less, something to be aware of.
SET THE WATCH IN 4 STEPS:
1. First, set the GMT hand to your time zone, to the nearest hour thats just passed.
2. Second, adjust the minute/hour hand to the actual time.
3. Third, adjust the hour hand.
4. Finally set the date.
STEP 1 - Set the GMT Hand
Always set the GMT hand to the hour that has just passed in your time zone. For example, if it's 05:15, then you would start out by calibrating it to 05:00. If it's 16:38, then you would set it for 16:00.
- First fully pull out the crown to position 3.
- Then adjust the crown anti-clockwise until the GMT hand is pointing to the correct hour on the bezel appropriate to where ever you are. Assuming the actual time is something like 16:38, then move the crown anti-clockwise until the GMT hand is pointing at the number 16 on the bezel or 08:00 on the dial, and the minute hand will be at 00:00 position (ignoring the hour hand for now).
- Push the crown back in to position 1.
- Done. The GMT hand is now set to your time zone.
STEP 2 - Set the minute hand
If you followed the instructions above, as per the example, you will need to wind the minute hand forwards now to the correct minute.
- First pull the crown all the way back out to position 3.
- Then move the crown anti-clockwise to the correct minute. In the example above, you would need to move it forward to 38 minutes (the GMT hand should also move forward slightly to co-ordinate).
- Push the crown back to position 1, and you're done.
STEP 3 - Set the hour hand
By now your GMT hand will be in the right place, and your minute hand will be correct too, so you just need to set the hour hand.
- First pull the crown all the way back out to position 3, then gently push it in with a very small click so it's at position 2.
- Then move the crown anti-clockwise until the hour hand is correct. In the example above this would be at 04 (for 16:38).
- Push the crown back in to position 1, and you're done.
STEP 4 - Set the date
By now your GMT, hour and minute hands will be in the right place, so now you just need to set the date right.
- First pull the crown all the way back out to position 3, then gently push it in a small click so it's at position 2.
- Then move the crown anti-clockwise in 24 hour cycles in order to increment the date forwards.
- Once the date is correct, make sure to keep turning the crown until the hour hand is back on the correct hour.
- Push the crown back in to position 1, and you're done.
Finally, screw the crown back in to position 0
