How accurate is the timekeeping on JH Factory Rolex Daytona 116520 Super Clone Watch

Direct answer, totally enough for daily wear, but don’t expect it to hit that extreme genuine chronometer accuracy. Base is the mature Shanghai 7750 movement. After tuning, real test daily error is basically around plus or minus 10 to 15 seconds. If you check forums for how much time error does Rolex Daytona replica watch have, you will find as long as daily error is within 20 seconds, it is normal for a mechanical watch. Timekeeping on this JH Factory Rolex Daytona 116520 Super Clone Watch is not as stable as the Dandong integrated movement, but the good part is the movement is tough and easy to repair. Just keep it away from strong magnets and don’t knock it hard. Totally enough for checking time on daily commute. No need to obsess over that few seconds difference.
