This Carnival men's mechanical watch is a great accessory. To use it, first, if you choose the mechanical hand - wind option, gently turn the crown on the side of the watch to wind it up. For the automatic self - wind feature, just wear the watch regularly, and the movement of your wrist will wind it. The watch can show you multiple time zones, which is handy for travelers. It also has a complete calendar so you always know the date. When it comes to care, keep it away from strong magnetic fields as they can affect the movement. Although it's water - resistant up to 3Bar, don't wear it for long - term swimming or diving. To clean the leather band, use a soft, damp cloth. For the case, a dry, clean cloth will do the job. With proper use and care, this watch will serve you well for a long time.
