Ideally a fixed cup tool is used to remove the fixed cup. For DIY at home, oftentimes a big ass crescent wrench is enough to remove the fixed cup on old French bikes. Or a vise. There is also a well known 'cheat' method on Sheldon Brown's page.
Pull the cranks first. Then the adjustable cup. Dump out the spindle and bearings. Then take off the fixed cup. 70s Peugeots are usually French threaded which has a right hand threaded fixed cup, but that looks like it could be an 80s bike, which can be anything. Is there any writing on the other side?
+1 on getting a proper lock ring tool. IMO it is next to impossible to adjust properly without one. A basic open (one tooth) Hozan type is fine.

That is true, generally speaking. However, in this case the frame is going to be powdercoated.
