MAG Wall Large Analog Wireless NTP Time Disaster Nighttime Second Hand Diameter Noah Precision Clock, Clock, Wi-Fi Connectivity, LAN, Synchronization,

This wall clock displays the accurate time using your indoor internet connection (Wi-Fi). It connects easily without an app. If you have a Wi-Fi connection, it automatically adjusts the time once a day. You can choose your preferred NTP server during setup. This product synchronizes with a single network time information (NTP) within the facility, so there will be no individual time differences between clocks installed in each room, for example. It is recommended for seminars, examination venues, and other locations that use multiple rooms. In addition, since it allows you to set the time zone (time difference), it is also useful in business settings where foreign time displays are required. This wireless LAN clock is perfect for situations where radio waves are difficult to receive, such as in office buildings or apartments. It can be easily set up if you have a wireless LAN (Wi-Fi) environment in your room and a smartphone (Android/iPhone), tablet, or PC. Once set up, you won't need to reconfigure it after battery changes or other adjustments. The second hand is a step second hand that moves in one-second increments. It has a function to stop the second hand's movement at a specified time, such as at night. Please be sure to use two AA alkaline batteries (sold separately). The battery life is approximately 12 months. The main unit dimensions are 42.0 x 42.0 x 4.7 cm, and the weight is 985 g. This wall clock is quite large, with a diameter of 42 cm, making it ideal for use in large spaces such as offices, conference rooms, and commercial facilities. Unlike some clocks that are often avoided depending on the location and environment, this one does not use glass; instead, the main body's crystal (the transparent front part) is made of plastic.
