WEARING THE WATCH FOR THE FIRST TIME

Before being worn for the first time, or if it has stopped, a Rolex watch must be wound manually in order to function correctly and precisely. 
To wind the watch manually, unscrew the winding crown completely, then turn it several times clockwise. (Turning in the other direction has no effect.) A minimum of 25 turns is required for adequate partial winding. The watch will then be wound automatically as long as it is worn on the wrist. Carefully screw the crown back down against the case to ensure waterproofness.

The green seal accompanying your Rolex watch is a symbol of its status as a Superlative Chronometer. This exclusive designation attests that it has successfully undergone a series of specific final controls by Rolex in its own laboratories in addition to the official COSC certification of its movement. This unique testing of its chronometric precision, waterproofness, self-winding and reliability pushes back the boundaries of performance and makes Rolex a benchmark for excellence in mechanical watches.

THE HEART OF THE SKY-DWELLER MODEL

DUAL TIME ZONE AND 24-HOUR DISPLAY

The Oyster Perpetual Sky-Dweller allows the traveller to read the time in two different time zones simultaneously.
When travelling, the wearer can read the reference time in 24-hour format via a rotating off-centre disc. A fixed red triangle on the dial points to the time. 

Local time is indicated by the conventional centre hour, minute and seconds hands. It can be set quickly and easily by jumps of the hour hand. Setting the hour hand does not affect the minute or seconds hands or the reference time. 
The instantaneous date change is linked to local time. Thus, the date window always displays the current date in the wearer’s local time zone. 

SAROS ANNUAL CALENDAR

• The Oyster Perpetual Sky-Dweller has an extremely reliable annual calendar thanks to an ingenious mechanism named Saros, patented by Rolex, and whose unique design was inspired directly by the astronomical phenomenon of the same name. 
• This annual calendar automatically differentiates between 30-day and 31-day months. It displays the correct date throughout the year and requires only one adjustment a year – on 1st March, February having only 28 or 29 days.

• The current month is indicated in red in one of the 12 windows around the circumference of the dial: January at 1 o’clock, February at 2 o’clock, and so on. 

  

  

RIN  COMMAND SYSTEM

The Ring Command system is a system of interaction between the case and movement developed and patented by Rolex for easy selection and adjustment of particular functions via a rotatable bezel and the winding crown. On the Oyster Perpetual Sky-Dweller, it allows easy selection of the function to be set: date, month, local time or reference time.

Description

The Rolex Oyster Perpetual Sky-Dweller Watch 326938SRO is a masterpiece of watchmaking that combines functionality and style. The watch's dual-time zone display is ideal for frequent travelers, allowing them to keep track of time in two different time zones. The annual calendar, which automatically adjusts for months with 30 or 31 days, is a convenient feature that eliminates the need for manual adjustments. The Ring Command Bezel is a unique invention that allows the wearer to set the time, date, and dual-time zone display with a simple turn of the bezel.

USING YOUR WATCH

OVERVIEW

1. Hour hand
2. Minute hand
3. Seconds hand
4. The reference time display  on 24-hour disc
5. Date window
6. Month display in one of 12 windows (January at 1 o’clock,  February at 2 o’clock, etc.) 
7. Bidirectional rotatable bezel
8. Twinlock winding crown with double waterproofness system

SETTING THE WATCH

Screwed-down position (crown in position 0) 
The crown is completely screwed down against the case. When the crown  is in this position, the Oyster Perpetual Sky-Dweller is guaranteed waterproof to a depth of 100 metres (330 feet).

Manual winding (crown in position 1) 
The crown is unscrewed. To wind  the watch manually, turn the crown clockwise; turning in the other direction has no effect. When setting the watch for the first time or after the watch has stopped, complete a minimum of 25 turns for partial winding.

After every use, carefully screw the crown back down against the case to guarantee the waterproofness. Return the crown to position 1 and apply light pressure on it while screwing it down clockwise against the case. The crown should never be unscrewed underwater.

COMPLETE SETTING OF THE WATCH IS CARRIED OUT BY FOLLOWING THE STEPS IN THE ORDER GIVEN

1. Setting the reference time (bezel in position III, crown in position 2)
   To set the reference time, follow the steps in the order given:
   • Unscrew the crown and then pull it out to the first notch.
   • Put the bezel in position III by turning it counterclockwise as far as it will go. The seconds hand is stopped, allowing you to set the time to the precise second.

   • Set the hour on the 24-hour disc and the minutes shown by the centre minute hand by turning the crown in either direction.
     Setting the reference time (hour on the 24-hour disc and minutes shown by the centre minute hand) also moves the hour hand (local time). For this reason, the reference time must be set before setting the local time.

     

     After every use, carefully screw the crown back down against the case to guarantee the waterproofness. Return the crown to position 1 and apply light pressure on it while screwing it down clockwise against the case. The crown should never be unscrewed underwater.

2. Setting the local time (bezel in position II, crown in position 2) 
   To set the local time, follow the steps in the order given:
   • Put the bezel in position II.
   • Set the local time (displayed by the hour hand) by turning the crown in either direction. The 24-hour disc and the minute hand do not move. Only the hour hand moves in increments of one hour. The date changes when the hour hand reaches midnight, only in the clockwise direction. 

   • To avoid confusion between a.m. and p.m. hours, move the hour hand to 12 o’clock. If the date changes, it is midnight.

     

     After every use, carefully screw the crown back down against the case to guarantee the waterproofness. Return the crown to position 1 and apply light pressure on it while screwing it down clockwise against the case. The crown should never be unscrewed underwater.

3. Setting the month and the date (bezel in position I, crown in position 2) 
   To set the month and the date, follow the steps in the order given:
   • Put the bezel in position I.
   • Set the month by turning the crown in either direction. Cycle through the dates and months until you reach the current month, which is indicated by a contrasting colour in one of the 12 windows around the circumference of the dial: January at 1 o’clock, February at 2 o’clock, etc. until December at 12 o’clock.
   • Set the date of the current month by turning the crown in either direction until you reach the correct date. The annual calendar automatically differentiates between 30-day and 31-    day months. It requires only one adjustment a year – on 1 March, February having only 28 or 29 days.
   • Return the bezel to the neutral position by turning it clockwise as far as it will go.

   • Push in and screw down the crown.

     

     After every use, carefully screw the crown back down against the case to guarantee the waterproofness. Return the crown to position 1 and apply light pressure on it while screwing it down clockwise against the case. The crown should never be unscrewed underwater.

SETTING THE LOCAL TIME  OR DATE ONLY

To change only the local time or the date, follow the steps in the order given:

• Unscrew the crown and pull it out to the first notch.
• Go to step 2 or to step 3 depending on the function to be set.

ROLEX SERVICE 

CARING FOR YOUR ROLEX 

You can help preserve its lustre by cleaning it occasionally with a microfibre cloth. You can also wash the case and bracelet from time to time using soapy water and a soft brush. After wearing your watch in the sea, it is important to rinse it with fresh water to remove any salt and sand deposits.

Before cleaning your watch, always ensure that the crown is screwed down properly against the case to guarantee waterproofness.

AFTER-SALES  SERVICE

1. Rolex watch servicing ensures that  your timepiece will continue to  perform optimally and meet Rolex’s stringent requirements in terms of precision, reliability and waterproofness throughout its life.
2. The timekeeping accuracy of your watch is largely dependent on high-performance lubricants specially developed by Rolex to minimize friction and prevent wear  of components. To guarantee continued accuracy and waterproofness, Rolex recommends that you periodically return your watch to an Official Rolex Retailer or Service Centre for professional servicing, which will always be carried out by a Rolex-approved watchmaker.
3. During a complete service, the watch is dismantled and all of its components the case, bracelet and movement – are closely examined.
4. The movement is entirely disassembled and all the parts are carefully inspected. Those that no longer meet Rolex requirements are systematically replaced by new components. The movement  is lubricated on reassembly. The case and bracelet are re-polished or satin-finished according to their original finish, restoring their shine and lustre while removing any marks or scratches. 
5. At the end of the process, your Rolex watch undergoes a series of tests to verify its functions, waterproofness and power reserve, as well as the precision of its movement.
