Using this Shinola Circadian Monster watch is easy. Just wear it on your wrist and the automatic movement will keep it running as long as you're moving. When setting the time, gently pull out the screw - down crown and turn it to adjust. Remember, this watch is water - resistant up to 100 meters, but don't leave it submerged for too long. To keep it in great shape, wipe it with a soft cloth regularly. Avoid hitting it against hard objects. If you're not wearing it for a while, store it in a dry and cool place.
