Insert several batteries and the clock is ready to go. There is really no setup except deciding where to place your clock.The clock is close to perfect if you want an easy to read clock that displays time, date, and temperature inside and out. It's very thin and easily wall mountable or can be placed on a flat surface against a wall. The numbers are large enough to read at great distances. The display is absolutely perfect and can be seen up to 20-30 feet away. It also can be placed on a desk if facing a wall.It seem like an outstanding wall clock and if it lasts and continues to provide accurate time is a superb purchase, Overall, it is well worth the asking price and I'm glad I bought it. ### ⭐⭐⭐⭐⭐ Big, easy to read time *by on Reviewed in the United States December 22, 2024* This is our fourth Marathon timepiece, and the 2nd with automatic time set. They improved the Time Zone setting to a slide switch on the back instead of going through the options. And, AA batteries are included, so I was able to set this up out of the box.The clock digits are large and are clear from across the room, at all angles. The outdoor temperature is nice to have, as is the Day and Date display. ### ⭐⭐⭐⭐⭐ Awesome clock, people comment on how nice it is at parties *by on Reviewed in the United States November 2, 2019* The numbers are really big, in my setup, it is great to be able to see it across the room on the couch. I also think the layout is really well done. I give this 5 stars, but it could be a little less money, but I guess you get what you pay for. If the batteries that come with it don't last and entire year, they will replace them. I like long battery life, it means they have made a good design. I had a clock where the outside transmitter battery didn't last more than a month. I'm hoping this one will last a year as advertised. ## Frequently Bought Together - MARATHON Atomic Full Calendar Clock with Extra Large Digits Indoor and Outdoor Temperature - Sharp Atomic Clock - Never Needs Setting! –Easy to Read Numbers - Indoor/Outdoor Temperature, Wireless Outdoor Sensor - Battery Powered - Easy Set-Up!!
