this one (see link below) is expensive but we really liked it for my mom when she was about stage 3 or 4. She had difficulty determining if it was day or night. This company has another one for day of the week--that one was not particularly helpful for us. https://www.alzstore.com/day-night-clock-p/h006...

In the UK but there might be a similar click where you are. It’s called “myhomehelper.com” It is relatively expensive but great time display. Relatives can post prompts and photos. It doesn’t need any user input. It has a system called VSee to communicate like Skype. Again, remotely controlled. It has different colour settings etc. It does have a monthly subscription of £7.99. Customer support is good. It’s a 10 inch tablet too and can access internet as normal. I bought a tablet stand to secure it. My dad has enjoyed looking at photos etc. I can also prompt him to take a drink. Get up and stretch! Anything really.

I bought one similar to the American Day Clock but now about a year after having it he rarely looks at it. He just keeps asking me the day and month etc.

We got the first one you mention. So far the before dawn has not been an issue as he is always sleeping then. We keep the clock where it can be seen from living and dining room.
He really does not pay much attention to it. His watch shows day, date and time and he checks that alot

The one you are leaning toward is like the one I have for my Mom. It has morning, afternoon, evening and night listed. My problem is getting my Mom to look at it.
