I think the year is wrong.

This  may be a "through the front" case, and might have a correct date inside.

Should have the letter and number code, not just a case SN.

Nice watch dude.

Are you sure the back comes off?

Sure looks like it's athrough-the-front type case to me.

so it finally managed to open, although it took nearly the thumb (I had to use gross force), but it turned out well        My suggestion to 1957 was correct movement is marked L7  inside the case is signed L7 too   outside sign is very indistinct      If you ever have the same problem, I attach a file case lock design, and watch out for your fingers :)

This is an all Bulova design, very interesting. What is the little dimple on the case back?

inside the case is extension which fits inside the movement and apparently used for transmitting vibration for alarm function

I wonder if it is a pressure valve?

That might explain the difficulty jabs had getting the back off!

Well done jabs, brave boy!

the pictures show a lot of dirt in my case it was just sintered and therefore could not easily open I am glad that it succeeded

Yep, Wrist Alarm, have fun getting the caseback back on. There's a bit of a trick to it, at least mine was.
