My watch is running fast/slow. How can I adjust it?Updated 6 months ago

Chronographs: Quartz movements like the Miyota 6S21 are known for their precision and should rarely run fast or slow. If you notice a significant deviation, the first step is to check the battery. A low battery can sometimes cause timing issues, so it may need replacement. If the problem persists after a new battery is installed, the movement may require servicing by a professional watchmaker.
