Dear customer, mechanical timers may have an error of 1 to 3 minutes. If you need accurate timing, it is recommended that you purchase an electronic timer

Note: Turn the timer clockwise once to the zero mark, then counterclockwise for the required time. At that time, the timer will ring a clear bell. Just turn it all the way to the bottom and then back. If it doesn't ring at 0 but around one minute, this is a normal phenomenon because it's mechanical. It's normal within three minutes. If you want very precise, only electronic timers can be accurate to the second. When you receive this product and use it later, "remember" not to "turn it in reverse";. Because she is wound up! Please pay close attention!!
