Pokemon rotom?

i need to catch him but i need to change my pokewatch how do i do that? the first pokewatchPokemon rotom?
to change the time on your pokewatch, you have to change your NDS's time. then the pokewatch will change along with the NDS. hope i helped!Pokemon rotom?
keep on trying
What do you mean? To change your watch to the first aap just keep tapping the reb button on the touch screen, you can't do it while you are battling though. What does this have to do with Rotom?
