The house we sold I had an Intermatic timer that looked like this:
At the new house I have a Woods 59101R timer that looks like this, except it's in an enclosure rated for all weather:
After using the Woods for a few days, I prefer this style of timer. It's a bit easier to set the time - with the Intermatic to get the set screw tight enough I needed pliers, so changing it meant tools. I've also discovered with the Woods that if I turn it on manually, when its off, it will run until the next interval and get turned off automatically. Handy when adding chemicals like this morning. I added pH increasr then left the house knowing the timer would turn the pump off.
