Thank you for viewing. This item is a travel-sized world time alarm clock. It is made by Omron, but the Omron mark is not on the lid. Instead, there is a flower mark. I checked online and found a product with the same model number and shape, so I am listing it as likely being made by Omron. Power has been confirmed. I am not sure how to use it, so I have only confirmed that it powers on. Batteries are not included. The item includes only the main unit. The item is unused, but it has some minor scratches due to long-term storage at home. Thank you for your understanding. Please consider purchasing.
