2 PCS Car Dashboard Clock, 1.57" x 0.31" High Precision Night Luminous Accurate Reading Time Quartz Clock, Alloy Durable Waterproof Adjustable Mini Clock, Universal for Cars (Black & Blue)

These are pretty small. As described, they are just over and inch and a half. The first picture shows them along with a quarter. These look like they are meant to be used in a watch band as a wrist watch.I was looking for a clock to put on the dash of my tractor so I can check the time without much effort. I mounted on the dash of the tractor (last picture) and I so far, it works fine.One modification I made was to use Velcro to attach the clock. Because the watch is so thin, I don't believe you'll be able to adjust the time if it is stuck to a flat surface with the double sided tape that is provided. With Velcro it will be easier to adjust the time and change the battery.For the price this is a simple, easy to read clock that you can stick about anywhere.

These clocks are adorable. They're the perfect size to fit on our golf cart dash without sticking out like a sore thumb. And I also love that unlike your typical "digital" stick-on clock, these are attractive and have personality. Plus, with the luminescent dials, you can tell the time at night. You get both black and blue clock faces and plenty of double-sided tape hangers. Very nice item.
