Great Timepiece

All Star Reviewer

This is a very large display and I like it because it has the day, date and time. I have not had a daylight savings change to check it with yet, but hopefully it will change as advertised. It did not change when I first got it as it says in the window and I had to reset it myself but luckily have enough knowledge of these clocks to do that. I like it.


Great Clock


from Oakville

Purchased as a Christmas gift for an older family member who has difficulty seeing . Have mounted on wall and are pleased with the ability to see the time from anywhere in the room. Also glad that it self adjusts the time.


Worth the price

Lovely clock to have.Am so glad I bought it and with the easy pay,helped a lot.It is very functional,with the large print makes it easier for everyone in my family to be conscious of the time.The only snag is that I would have love to know the temperature outside.So far I still love it.

Fabulous Clock

By Smokey

This lovely clock is on the wall in the front entrance of my house. Its the perfect size and you can see the numbers clearly. Its nice to see the time as you are leaving for appointments. You can also place it on a shelf or mantle. Love it and such a great buy!

I have bad eyesight and this clock is a perfect size . Set-up was easy insert batteries (included) place near a window overnight and the next day the time and date was set automatically. Also shows temp. Has built in flip out stand to place on table or wall mount it.
