Turn clockwise (clockwise): Slowly turn the crown clockwise (towards the 12 o'clock position). The mainspring will not wind if you turn it counterclockwise. Wind until it stops: Continue turning until the mainspring is fully wound. As you wind it, the resistance will gradually increase, and when it is fully wound, it will either stop turning or start to slip. Frequency: It is ideal to wind the mainspring clock once a day, at the same time if possible. This will help maintain the accuracy of the clock. How to set the time Pull out the crown: To set the time, pull the crown out one step (or two steps, depending on the clock's specifications) from the mainspring winding position. Turn the crown to set the time: Generally, turning the crown moves the hour and minute hands. Depending on the clock's mechanism, it may be recommended to turn the crown only in the forward direction. Turning it in the reverse direction may damage the internal parts, so if possible, set the time by turning the crown in the forward direction. Return the crown: Once the time is set, return the crown to its original position (pushed in). Precautions Avoid forced operation: If the crown is stiff or does not turn, do not force it and consult a retailer or repair shop. Regular maintenance: For long-term use, inspection and adjustment (overhaul) every 3-5 years is recommended. Thank you for viewing.
