Key Features of the Miyota 9122
1. Automatic Movement
The Miyota 9122 is an automatic movement, meaning that it is powered by the motion of the wearer’s wrist. As the wearer moves their wrist, a rotor inside the movement spins, winding the mainspring and providing power to the movement. This eliminates the need for a battery, making it a more sustainable and eco-friendly option compared to quartz movements.
The automatic feature is highly valued by watch enthusiasts, as it eliminates the need for battery replacements, ensuring that the watch continues to function without constant maintenance.
2. Date Complication
The Miyota 9122 features a date complication, which is a useful function that displays the current date on the watch dial. The date function is typically displayed through a small window on the dial, which changes automatically at midnight to reflect the correct date. This feature is highly practical for everyday use and is a common addition to many modern watches.
The date complication is powered by the movement’s gear system, which allows the date to be adjusted as the time progresses. The Miyota 9122 is known for its smooth date-change mechanism, which is a testament to the movement’s high-quality design.
3. Power Reserve
The Miyota 9122 boasts a power reserve of approximately 40 hours. This means that once fully wound, the movement can continue running for up to 40 hours without requiring any additional movement or winding. A 40-hour power reserve is typical for most modern automatic movements and ensures that the watch will continue to function for a day and a half before needing to be wound again.
The power reserve is an important feature for those who wear their watches infrequently, as it ensures that the timepiece will remain accurate even if it is not worn every day.
4. Frequency and Precision
The Miyota 9122 operates at a frequency of 28,800 vibrations per hour (vph), which is a common frequency for many modern automatic movements. This frequency is crucial for the smooth movement of the watch’s second hand and ensures that the timekeeping remains accurate and consistent.
With a precision rate of -20/+40 seconds per day, the Miyota 9122 offers reliable timekeeping that is suitable for most everyday wearers. While it may not be as precise as higher-end Swiss movements, it is still more than adequate for the average watch wearer and is considered excellent for its price range.
5. Durability and Build Quality
Miyota is known for producing movements that are durable and reliable, and the 9122 is no exception. The movement is built to last, with robust components that are designed to withstand everyday wear and tear. The use of high-quality materials in the construction of the movement ensures that it remains accurate and functional over time.
The Miyota 9122 also features a solid and dependable construction, with a robust balance wheel and a smooth rotor system. This makes it a reliable choice for both casual and active wearers, as it can handle the rigors of daily life without compromising on performance.
