FAQs

Sapphire is renowned for its durability and luxury. Made from high-quality, pure sapphire crystal, these cases are designed to be exceptionally resistant to scratches and damage. Sapphire is one of the hardest materials known, second only to diamond, making it highly resistant to everyday wear and tear.

However, while sapphire is incredibly hard, it is also somewhat brittle. This means that while it can withstand scratches and general impacts better than many other materials, it can still break or shatter if subjected to a significant impact or extreme force. It’s important to handle sapphire cases with care to avoid accidental drops or hard knocks.

In summary, while sapphire cases are highly durable and resistant to scratches, they are not entirely immune to breaking if exposed to severe conditions. For best results, treat your sapphire case with care to maintain its pristine condition and longevity.

If your watch is running fast or slow, it could be due to several reasons:

1. Power Reserve Issues: For automatic watches, insufficient movement can lead to a low power reserve. Try winding your watch manually and see if the issue improves.
2. Magnetization: Mechanical watches can be affected by magnetic fields, causing them to run faster. If you suspect magnetization, a professional can demagnetize the watch.
3. Maintenance Needs: Over time, the watch's internal parts may need lubrication or repair. Lack of oil or worn components can affect timekeeping. Regular maintenance by a professional can resolve these issues.
4. Impact or Shock: Dropping or bumping your watch can disrupt its internal mechanisms and affect accuracy. Handle your watch with care to prevent damage.
5. Environmental Factors: Temperature changes and how you wear the watch can also impact timekeeping.

If you experience significant timekeeping issues, we recommend sending your watch to a designated repair center for inspection and adjustment.

Mechanical watches rely on intricate internal mechanisms to keep time accurately. Due to factors like gravity, temperature changes, and the mechanical nature of the movement, some variation is normal.

Typically, the daily error of a mechanical watch can vary depending on the model and quality of its movement. According to the Swiss Federal Standard, a daily error of less than 30 seconds is considered within the normal range.

If your watch is running outside this range, it may require adjustment or maintenance.

If your automatic winding watch stops, follow these steps:

1. Manually Wind the Watch: Even though your watch is automatic, it can benefit from manual winding if it has stopped. This helps to jumpstart the movement. Turn the crown clockwise to wind it.
2. Check the Power Reserve: Automatic watches typically have a power reserve of about 42 hours. If the watch hasn’t been worn or has seen minimal movement, it might run out of power. Regularly wearing the watch or winding it manually will help maintain its power reserve.
3. Wear Regularly or Wind Periodically: If you’re not wearing the watch frequently or for long periods, make sure to wind it manually every few days. This keeps the movement lubricated and in good working condition.

By keeping these practices in mind, you can ensure your automatic watch remains accurate and functional.

High-tech ceramic is known for its impressive scratch resistance. At CRONUSART, we define "scratch-resistant" as the ability to withstand scratches from normal, everyday use. Rado high-tech ceramic is designed to offer a very high level of scratch resistance.

However, while it is highly resistant, it is not entirely immune to scratches. If the ceramic comes into contact with materials that are as hard as or harder than itself—such as granite, sand, or nail files—it can potentially be scratched.

To maintain the pristine condition of your watch, avoid exposing it to extremely hard materials and handle it with care.
