Timer balls are pokeballs but are more effective the longer the battle has been going.

A timer ball is good to use when you want to catch a Pokemon you've battled for a while. The more turns you have in a battle, the better more chance you have to catch to Pokemon with a timer ball. (I caught my Groudon in Emerald with a timer ball ^_^)
Once you help the Devon corp you can purchase timer balls and repeat balls at the rustboro city pokemart.
You can buy timer balls at Canalave city and at the Pokemon League.
