Help finding a digital dress watch under $25

I am looking for a dress watch but I’m finding it almost impossible to find what I need. So I though I’d appeal to the wonderful people at SD. I’m looking for something that’s a dress watch but is still digital and has a timer, like a lot of sports watches do. It would also be nice if it gave the date and day of the week. I work in schools so I need something where I can easily give a countdown (“One minute to pick up to toys! Lets see if we can do it!”). Or where I can time how fast kids can do something. But it still needs to be professional. I am having a lot of trouble finding one, much less one in my price range of under $25. Why on Earth don’t they make these? Thanks!

Also, I’m not very good at quickly assessing analog time, that’s why it needs to be digital. Thanks!

Thank you!

I’m surprise there are digital watches that look that good, seem that functional and cost less than 20$. Any idea of how durable they are?

It seems Casio makes a lot of them. What’s that brand known for?
