is this a fake tissot PR516 roger moore from the 70s

Hello,

I am not an expert on Tissot watches, but I got this PR516 Automatic today. Is it normal for it to be so small and for there to be no "T" above "Tissot" on the PR516?

The watch is 25 mm and so tiny. Is it genuine?

Sorry for the title! 😀
Here are some pictures.

Thank you!
