I need serious help finding a book!

It’s a book I read back when I was in elementary school I think.

It’s one of those fun interactive books like the “Ology” series of books, but it followed the story of a time traveler.

I recall it having a big gray cover and a watch in the bottom corner of the cover if that helps.

Sadly I recall nothing about the author or character names though.

If anyone knows anything about this book please let me know!
