Totally confused now, do you want to know the model of one watch or how to open the other? -

The other watch is an Omega De Ville automatic tank watch (1970s I think). This watch has a Cal 684 movement. Once again my question is related to the case. I have attached a group of pictures and I am hoping someone can tell me how to open the watch. I have learned not to pry too much if I don’t find a notch to put a blade into. I have read about Omega tank compressor cases that have some sort of pins holding them on but the dimensions of this case do not match the dimensions of those cases. The actual movement looks pretty straightforward . Thanks for your help! I’ll add pictures but the dial is not original to the watch. It says “Automatic “ but the 420 is a manual wind. The 420 movement is original to the case as it is listed as the movement used in PX 6553 models. I was hoping the model number from the case would be enough. I don’t have the watch any longer but here are some pics I took. Thanks. -

A friend of mine asked me if I could fix two vintage Omega watches. One from 1954 and one from the 1970s I believe. The older watch is a PX6553 with a cal 420 movement (I would love to know the model name if anyone knows). The 420 needed a complete service and is now running great. -
I think you'll find there are too many sizes and pitches of thread across different brands for it to be possible. I've been considering one of these that may work to hold screws but would probably make some plastic jaws. You could try putting rodico in the holes but not sure if this would hold the screws well enough.
