Manual wind

 

Hi

the case reference is for a flat Seamaster, probably a Seamaster 30.  This was produced with a manual wind movement of the 30mm series,
i.e. a 28x or a 26x movement.   This case would not accept the automatic-date 562.

The cal 562 was a chronometer-grade automatic.  It was used in some Constellation watches and in some Seamasters (but not the case that you have).

If you do a search on Google you will easily find some of those references who used it.
