Learn to set the dual time zone hand on your Steel Torsk-Diver Pro GMT 39. Step-by-step instructions for the Raven Purple preorder and other models.

Quick answer

Pull the crown to position 2 to set the local hour and minute hands, then use the 24-hour GMT hand to track a second time zone. The GMT hand moves independently and is adjusted by rotating the bezel or crown, depending on your model.

Understanding the GMT hand on your Torsk-Diver Pro 39

The Steel Torsk-Diver Pro GMT 39 uses a caller GMT movement, meaning the 24-hour hand is linked to the main hour hand. You set the local time normally, then the GMT hand tracks a reference time zone (like UTC or your home time). This is the most common setup for travel watches and is straightforward once you know the sequence.

On the Raven Purple preorder model (delivery late August 2026), the GMT hand is the smaller, arrow-tipped hand with a 24-hour scale on the bezel. The bezel can be rotated to read a third time zone if needed.

Step-by-step: Setting the GMT function

Step 1: Unscrew the crown: Turn the crown counterclockwise until it pops out to position 1 (manual winding position). Do not pull it out yet. Common mistake: pulling the crown too hard before unscrewing can strip the threads. Always unscrew fully first.
Step 2: Set the local time: Pull the crown to position 2 (date setting position). Rotate the crown clockwise to advance the hour and minute hands to your current local time. The GMT hand will move in sync with the hour hand. Checkpoint: Make sure AM/PM is correct by advancing past 12 and noting if the date changes. If it changes, you are in AM.
Step 3: Set the GMT hand to your reference time zone: Push the crown back to position 1 (winding position). Turn the crown to rotate the GMT hand independently to the desired 24-hour time (e.g., UTC or home time). The hour and minute hands will not move. Common mistake: trying to set the GMT hand while the crown is in position 2. It only adjusts in position 1.
Step 4: Use the bezel for a third time zone (optional): Rotate the 24-hour bezel to align the triangle marker with the GMT hand’s position. Each bezel click represents one hour. For example, if the GMT hand points to 14 (2 PM) and you rotate the bezel 3 clicks, you are reading a time zone 3 hours ahead. Checkpoint: The bezel is unidirectional on dive watches. Turn it only counterclockwise to avoid accidental misalignment.
Step 5: Screw the crown back: Push the crown fully in and turn clockwise until snug. Do not overtighten. Empty
