Welcome to the forum.

Can you post some photos showing the back along with some side views.

Edit

Just realised it's an Automatic so doesn't have a battery.

It needs movement or possibly winding with the crown (depending on the movement inside) to work.

Without any indentations, must be a snap back

Like I said in my edit above, it doesn't have a battery.

Try winding with the crown.

Oh so that is why it is gyromatic so if I don’t move it every once in a while it turns off? That seems a tad bit redundant but kinda cool thanks so much

That will teach me to read the post properly.

Let's see the dial.

I expect you should be able to wind it by hand with the crown and then when wearing it the 'gyromatic' part keeps it topped up, for want of a better phrase.

Here is the clearest possible example demonstrating how your fine Gyromatic works https://ciechanow.ski/mechanical-watch/
