Hi & welcome, tinger!
That´s a very nice President De Luxe with an unusual dial design - to be honest, the first one I see with this dial.
It has one of the first bayonet case backs, still with "Patent demanded" instead of the patent number on it(ATTENTION! The bayonet case back is to be turned 30° only at opening/closing).
That dates the watch to 1957/58. The moving anchor logo is already present, I assume an AS(Adolf Schild) automatic movement inside, probably an AS 1580. Is there any reference number(11xxx) on the case, maybe inbetween the lugs?
If you want to wear it regularly, you should have it serviced by an old school watchmaker(COA - cleaning, oiling, adjusting). If the oil is empty, the movement will be finished in a while.
Hope this helps a bit.
