In July 2025 I bought my first WiFi controlled wall clock from Amazon. It is the “WiFi Analog Wall Clock with Auto Sync Time & DST, 12 Inch, Silent, Battery Operated, Smart Wall Clock – Modern Classic Style for Office, Living Room, Bedroom, Kitchen, and Home (Black)“. In other works a standard looking 12” wall clock, but this one syncs its time via WiFi. This clock is made by Koosome. I was intrigued since it is a WiFi syncing clock, not the older Atomic Clock syncing style. After running it for a couple of weeks I can report it works as advertised. 

I have two cons to report. First, the interface  between your cell phone, your WiFi network, and the clock is not very user friendly. It is not designed to do anything but setup the WiFi connection and then let the clock figure everything else out. My second con is that Koosome does not provide any web based support that I can locate, other than on Amazon’s and Walmart’s websites. I was not able to find a PDF version of the rather brief user manual.

If an effort to help fellow clock and IT enthusiasts around the world, I scanned the user manual and prepared the PDF file at the link below. I hope that it is helpful.

I will give this clock five stars on Amazon. It is well worth the price of $33.99 (as of today, July 19, 2025). I put it in my bathroom. My wife is not crazy about a 12 inch clock in a bathroom, but I find it very helpful.
