1. Note: Must be wound to 55 (no more than 55). Do not turn it back to 0. Turning it counterclockwise from 0 will damage the mechanism. The mechanical timer does not have a battery. Any time you need to wind it first, simply wind all the parts at once to 55 (no more than 55). Be sure to read and follow the adjustment instructions: turn clockwise to 55 minutes, then turn counterclockwise to the desired time to set. The timer requires manual winding. 2. Turn only the animal's head, do not wind the base; it is perfect for kitchen enthusiasts, not only as a timer but also as a home decoration. You will love this cute and practical friend. It has a certain time deviation of +/- 5%. If you do not buy it, thank you. ABS: All interfaces are carefully polished and there are no sharp spots. It is a lovely thing to put in your room, office, or kitchen. 4 Manage your time: Helps you learn time management, especially for cooking, baking, brushing teeth, reading, studying, running, yoga, facial mask beauty, coffee and tea time, etc. A great gift for family and friends.
