It's an automatic based on the ASchild 500x movement

and this is from the Dr. Ranfft's database:

Caliber AS 5008
Just some 175 000 samples were produced 1973-1977 and most applied by Bulova, Certina, Dugena, Longines, and Pallas-Eppo. Today alarm watches are assembled using old stock by e.g. Bulova, Eterna, Maurice Lacroix, Nivrel and Ulysse Nardin. For manufacturers covering the medium price range it grows difficult to get samples of this movement at reasonable prices. So probably this kind of watch will come in the future exclusively as luxury item.
