2. Setup and Initial Operation
2.1 Winding the Watch
Your Rado True Square features a Swiss automatic movement. This means the watch is powered by the motion of your wrist. If the watch has stopped or its power reserve is low, it can be manually wound:
- Unscrew the crown (if applicable) and pull it out to the first position.
- Rotate the crown clockwise approximately 20-30 times. This will initiate the movement and build up a sufficient power reserve.
- Push the crown back into its original position and screw it down securely to ensure water resistance.
Wearing the watch regularly will keep it wound. The movement has an impressive 80-hour power reserve when fully wound.
2.2 Setting the Time
- Unscrew the crown (if applicable) and pull it out to the second position (farthest out).
- Rotate the crown in either direction to set the hour and minute hands to the correct time.
- Once the time is set, push the crown back into its original position and screw it down securely.

2.3 Adjusting the Bracelet
The white high-tech ceramic bracelet is designed for comfort and durability. For proper fit, the bracelet may need to be adjusted by adding or removing links. It is highly recommended that bracelet adjustments be performed by an authorized Rado retailer or a professional watchmaker to prevent damage to the ceramic links and titanium deployment clasp.

3. Operating Your Automatic Watch
3.1 Automatic Movement
Your Rado True Square watch is equipped with a self-winding mechanical movement. This movement contains a rotor that oscillates with the natural motion of your wrist, winding the mainspring and powering the watch. When fully wound, the watch has a power reserve of approximately 80 hours, meaning it can continue to run for this duration even when not being worn.
3.2 Water Resistance
This watch is water resistant to 50 meters (5 ATM). This rating makes it suitable for everyday use and can withstand splashes, rain, and brief immersion in water. It is not recommended for swimming, diving, or showering, as water pressure and temperature changes can compromise the seals. Always ensure the crown is fully pushed in and screwed down (if applicable) before any contact with water.
4. Maintenance and Care
4.1 Cleaning
The high-tech ceramic case and bracelet are highly scratch-resistant and easy to clean. To clean your watch:
- Wipe the watch with a soft, damp cloth.
- For more stubborn dirt, use a mild soap solution and a soft brush, then rinse thoroughly with clean water.
- Dry the watch completely with a soft, lint-free cloth.
Avoid using harsh chemicals, abrasive materials, or ultrasonic cleaners, as these can damage the watch's components or finish.
4.2 Regular Servicing
Like any precision mechanical instrument, your Rado automatic watch requires periodic servicing to maintain its accuracy and performance. It is recommended to have your watch inspected and serviced by an authorized Rado service center every 3-5 years. This service typically includes cleaning, lubrication, and adjustment of the movement, as well as replacement of seals to ensure water resistance.
4.3 Sapphire Crystal Care
The watch is fitted with a scratch-resistant sapphire crystal with an anti-reflective coating. While highly durable, it is not entirely impervious to damage. Avoid direct impacts and contact with extremely hard or sharp objects to prevent chipping or scratching.

5. Troubleshooting
- Watch has stopped or is running slowly: This is common for automatic watches if not worn regularly. Manually wind the watch as described in Section 2.1. If the issue persists after winding and wearing, the watch may require servicing.
- Time inaccuracy: Minor variations in timekeeping are normal for mechanical watches. However, if your watch is consistently gaining or losing significant time, it may indicate a need for adjustment or servicing by a professional watchmaker.
- Condensation under the crystal: If you notice condensation, it may indicate a loss of water resistance. Immediately take the watch to an authorized service center to prevent further damage to the movement.
