I would not consider him potty trained until he is able to feel the need to go and then go to the potty on his own. This will be difficult to achieve if you are requiring him to urinate every hour, not only will this by pass his need to feel a full bladder, but he will also not know what it feels like to completely empty his bladder. The method of potty training my son forced us to use was what I like to call the "bare naked truth" he would strip off all his clothes and do every thing naked for about 2 weeks. That way he could see when the pee started to come out and then he would run to the bathroom to pee. This way he learned quickly what his full bladder felt like. He has been fully potty trained now since 2 2mo. But I can't take credit for that we just let him do what came natural to him, we didn't pressure him or try to make him "go to the potty", but he did watch his daddy use the potty on a regular basis from about 9 mo (when he learned to open the door) until he was trained. Unless you are trying to get him trained for a preschool enrollment I wouldn't be too concerned with making him go to the potty. I think it may benefit him more to let him go when he feels he needs to go, and if he as an accident in his pants try and help him remember what his body felt like before he got wet so he can remember to go to the potty when he feels that way. I think some accidents are a necessary part of the learning process.
