How to safely set your Rolex Sky-Dweller

The Rolex Sky-Dweller is widely considered the most complicated watch Rolex makes. That complexity comes down to the impressive internal movement and how you interact with it.

Instead of relying on multiple buttons or pushers, you control everything through the Ring Command Bezel and the Crown working together. If you've just picked one up, setting it can feel a bit daunting. Let's break down exactly how to safely configure the time, date, month, and GMT functions without damaging your watch.

Step 1: Wind the watch in the locked position

When the bezel is turned fully clockwise, it sits in its locked safety position. If you unscrew the Crown and pull it out while the bezel is locked, it will turn freely but won't adjust any settings.

1. Unscrew the Crown and leave it in its first position.
2. Wind the watch clockwise to give the movement some power if it is completely dead.
3. Push the Crown back in so it rests in its non-function state.

Step 2: Avoid the danger zone

Before you adjust the date or month, you need to protect the movement. You should never set the watch when the time is between 21:30 and 03:00. Doing so risks shearing the internal teeth because the gears are already engaged to change the date.

1. Turn the Ring Command Bezel all the way to the left (anti-clockwise). This takes exactly three clicks.
2. Pull the Crown out and turn it to move the hands to a safe time. Setting it to 06:00 or 18:00 is always a safe bet.

Step 3: Set the GMT (second time zone)

With the watch safely at 6 o'clock, you can now set your reference time on the inner 24-hour disc.

1. Turn the Ring Command Bezel one click clockwise from its current far-left position.
2. Turn the Crown to adjust the 24-hour counter and set your second time zone.

Step 4: Set the month and date

The Sky-Dweller features an annual calendar. The month is indicated by the small red counter located just above the hour markers around the dial. For example, if the red marker sits at 11 o'clock, you are in November.

1. Turn the Ring Command Bezel one more click clockwise.
2. Turn the Crown to cycle through the dates. As you complete a full month of dates, the red month indicator will jump to the next hour marker.
3. Stop cycling exactly one day before your target date. For example, if today is the 5th of November, set the watch to the 4th of November.

Step 5: Synchronise the exact time

Now it is time to bring everything together and flip the date over to the current day.

1. Turn the Ring Command Bezel all the way back to the left (three clicks anti-clockwise).
2. Turn the Crown forward to advance the time past midnight. You will see the date click over to your current date.
3. Continue turning the Crown until you reach your current local time on the main dial.

Step 6: Lock it all down

Once your watch is set perfectly, you need to secure it to ensure it stays water-resistant and the settings are not accidentally bumped.

1. Depress the Crown and screw it down tightly against the case.
2. Turn the Ring Command Bezel fully to the right (clockwise) to return it to the locked safety position.

You're all set

That is everything you need to know to safely operate your Rolex Sky-Dweller. Always remember to check that the crown is fully screwed down before you wear it out.
