Tips

  • The GMT hand is usually set to your home time for reference.
  • The hour hand can be jumped in either direction.
  • There is no quick date set on the GMT-Master II.

Common Mistakes to Avoid

1. Incorrectly Setting the Date

Reason: Adjusting the date between 9 PM and 3 AM can damage the movement.
Solution: Always set the date outside of this timeframe.

2. Confusing the Hour Hand and GMT Hand

Reason: The GMT hand can be mistaken for the local hour hand, leading to incorrect time settings.
Solution: Understand the function of each hand, using the bezel to track a second time zone.

3. Ignoring the 24-Hour Hand's Position

Reason: Failure to align the 24-hour hand with the correct time on the bezel leads to inaccurate third time zone readings.
Solution: Ensure the 24-hour hand accurately represents the home or reference time zone on the bezel.

FAQs

Can I set more than three time zones on my GMT-Master II?
No, the GMT-Master II is designed for displaying three time zones simultaneously. While you can technically adjust the hands to represent more, it will lose its intended functionality and accurate timekeeping for each zone.
How do I quickly switch between my home time and a second time zone?
The easiest way is to use the independently adjustable hour hand. This hand represents your second time zone. Simply adjust it forward or backward in one-hour increments using the crown. Your home time (usually displayed on the 12-hour dial) will remain unaffected.
