Japanese movement in watches is not necessarily inferior compared to Swiss movement. Both Japanese and Swiss movements have their own strengths and weaknesses. Japanese movements, such as those made by companies like Seiko and Citizen, are known for their precision and durability. On the other hand, Swiss movements, particularly those made by brands like Rolex and Patek Philippe, are often associated with luxury and craftsmanship. Ultimately, the quality of a watch movement depends on the specific brand and model, rather than the country of origin. **

There could be several reasons why all your watches are running wrong. One possibility is that they may need to be serviced or have their batteries replaced. Another reason could be that they are being exposed to magnetic fields, which can interfere with their timekeeping. Additionally, extreme temperature changes or physical shocks can also affect the accuracy of the watches. It's best to have them checked by a professional watchmaker to determine the exact cause of the issue. **

No, you do not necessarily need a smartphone for fitness tracker watches. Many fitness tracker watches can function independently, tracking your activity, heart rate, and other fitness metrics without needing to be connected to a smartphone. However, having a smartphone can enhance the functionality of the fitness tracker watch by allowing you to sync and analyze your data, receive notifications, and access additional features through companion apps. Ultimately, whether or not you need a smartphone for a fitness tracker watch depends on your specific fitness tracking needs and preferences. **

No, not all Casio watches are radio-controlled watches. Casio offers a wide range of watches with different features and technologies, including radio-controlled watches that automatically sync with atomic clocks for accurate timekeeping. However, Casio also produces watches that do not have radio-controlled capabilities and rely on traditional quartz movements or other technologies for timekeeping. **

Automatic watches with an ETA movement are known for their durability and longevity. With proper care and regular maintenance, these watches can last for decades, sometimes even a lifetime. The ETA movements are renowned for their reliability and robustness, making them a popular choice among watch enthusiasts. Regular servicing every 5-7 years is recommended to ensure the watch continues to function smoothly and accurately. **

Analog watches without a second hand do not have a continuously running second hand. Instead, they only have hour and minute hands to indicate the time. Some digital watches also do not display a second hand, as they only show the hours and minutes in numerical form. These types of watches are often designed for simplicity and a more minimalist look. **

Some good fitness watches that measure calorie expenditure around the clock include the Fitbit Versa 3, Garmin Venu 2, and Apple Watch Series 6. These watches use advanced sensors and algorithms to track your activity levels, heart rate, and other metrics to provide accurate estimates of calorie expenditure throughout the day. They also offer features such as personalized insights, workout tracking, and goal setting to help you stay on top of your fitness goals. **

Automatic watches are generally not as accurate as quartz watches. Quartz watches are powered by a battery and use a quartz crystal to keep time, which results in very precise timekeeping. On the other hand, automatic watches are powered by the movement of the wearer's wrist and rely on a complex system of gears and springs, which can lead to slight variations in timekeeping. While automatic watches can be very accurate, they typically require periodic adjustment to maintain their accuracy, whereas quartz watches are known for their consistent and reliable timekeeping. **
