How to Read a GMT Bezel: A Practical Guide for Steel Torsk GMT 39 Owners

Quick Answer

To read a GMT bezel on your Steel Torsk GMT 39, first set the 24-hour hand to your home time zone, then rotate the bezel so the number corresponding to your second time zone aligns with the 12 o'clock position. The 24-hour hand will then point to the current time in that second zone. Practice with a known time zone to avoid confusion.

The GMT bezel on your Steel Torsk GMT 39 is a powerful tool for tracking multiple time zones, but it can be intimidating if you're new to GMT watches. This guide breaks down how to read and use the bezel effectively, ensuring you can navigate time zones like a pro.

Whether you're a frequent traveler or simply need to coordinate with colleagues across the globe, understanding the GMT bezel adds practical value to your watch. Let's dive into the mechanics and get you comfortable with this feature.

Understanding the GMT Bezel

The GMT bezel on your Steel Torsk GMT 39 is a rotating ring marked with 24 hours, often in two colors to distinguish day and night. It works in conjunction with the watch's 24-hour hand, which completes one full rotation every 24 hours instead of 12. This allows you to read a second time zone by aligning the bezel with the 24-hour hand.

Your Steel Torsk GMT 39 is powered by the Miyota 9075 True GMT automatic movement, which features an independent 24-hour hand that can be set separately from the main hour hand. This 'true GMT' function makes it easy to adjust the local hour without affecting the home time reference, a key advantage for travelers.

• The bezel is bidirectional on many GMT watches, but always check your specific model's instructions.
• The 24-hour hand often has a different shape or color to distinguish it from the main hour hand.

Setting Your Home Time Zone

Before using the bezel, you must set the 24-hour hand to your home time zone. Pull the crown to the appropriate position (usually the second click) to set the hour hand and the 24-hour hand together. Rotate until the 24-hour hand points to the correct hour on the 24-hour scale, keeping in mind that the main hour hand should show your local time.

For example, if you're in New York (EST) and it's 3 PM, the 24-hour hand should point to 15 (or 3) on the dial. Ensure the AM/PM is correct by checking that the hour hand is on the correct side of 12. This step sets your reference point for all other time zones.

• Always set the 24-hour hand to your home time zone first, not the second time zone.
• If your watch has a date function, set it after establishing the home time to avoid date confusion.

Using the Bezel to Track a Second Time Zone

Once your home time is set, you can track a second time zone by rotating the bezel. To do this, subtract the UTC offset of your home time from the offset of the desired time zone. For instance, if you're in New York (UTC-5) and want London (UTC+0), the difference is +5 hours. Rotate the bezel counterclockwise by 5 hours (or clockwise, depending on your watch's design) so that the 24-hour mark on the bezel aligns with the 12 o'clock position.

After this adjustment, the 24-hour hand will point to the current time in London on the bezel's 24-hour scale. For example, if it's 8 PM in New York, the 24-hour hand points to 20, which on the bezel will read 1 AM (or 01) the next day in London. This method works for any time zone, provided you know the UTC offsets.

• Remember: the bezel rotates, so the numbers on it move relative to the fixed 24-hour hand.
• Practice with a familiar time zone to verify your bezel adjustment is correct.

Common Mistakes and How to Avoid Them

One common mistake is confusing the 24-hour hand with the main hour hand, especially in low light. The 24-hour hand on the Steel Torsk GMT 39 is typically slimmer or has a different color, but if you're unsure, pull the crown to set the time and observe which hand moves independently. Another pitfall is forgetting to account for daylight saving time, which can shift UTC offsets by an hour. Always verify the current offset for the time zones you're tracking.

Additionally, ensure you rotate the bezel in the correct direction. Most GMT bezels are bidirectional, but some are unidirectional for dive purposes. On a GMT watch, rotating the bezel clockwise or counterclockwise should be intuitive; if you're unsure, consult your manual. If you set the bezel incorrectly, the time will be off by hours, so double-check your math.

• Use the 24-hour hand's shape to distinguish it from the main hour hand.
• Check if your time zones observe DST and adjust accordingly.

Step-by-Step: Reading the GMT Bezel

1. Set the 24-hour hand to your home time: Pull the crown to the time-setting position and rotate until the 24-hour hand points to your current hour (using the 24-hour scale). Ensure the main hour hand shows the correct local time. Checkpoint: The 24-hour hand should move in sync with the main hour hand when you rotate the crown.
2. Determine the UTC offset difference: Find the UTC offset of your home time zone and the desired second time zone. Calculate the difference (e.g., New York UTC-5, London UTC+0, difference +5). Mistake to avoid: Forgetting daylight saving changes can shift the difference by an hour.
3. Rotate the bezel to align with the second time zone: Rotate the bezel so that the number corresponding to the UTC difference (in hours) aligns with the 12 o'clock position. For a +5 hour difference, align the 5 marker (or 17 if using 24-hour markings) with 12. Checkpoint: After rotation, the 24-hour hand should point to the current time in the second time zone on the bezel.
4. Read the second time zone: Look at where the 24-hour hand points on the bezel's 24-hour scale. That number is the current time in the second time zone. Distinguish AM/PM based on the 24-hour format. Practice with a known time zone to confirm accuracy before relying on it.
