Special tiles appear every 15 speed matches. So what you want to do here is start a dash game and leave 32 tiles on it. After this, reset the speed bonus and start matching without losing the bonus.
When you match the 15th pair, a special tile will appear exactly on the two remaining tiles, so you got to be fast and click on them right after they appear. Since you know where they will appear it is easier than trusting on your reflexes.
I can guarantee you can do this with a mouse, since I done it.
This might need a couple of tries, because time tiles appear randomly with other special tiles.
Good luck also.
A simple way to get this, as pointed out by Rusty Nail, is to buy the Chrono Pack and I quote him: "you will have a time tile at the beginning of the 1st stage of the 1st level, which has 40sec on the clock. It's ready to match up, and you gain 40sec. plus the achievement popped".
As stated by Senior Chupon, the chrono DLC is, currently free.
