I use this at work to press watch-backs back on, and it's much better than the cheap lever style case presses. It's extremely well made, sturdy and does the job. There are lots of different sized plastic dies for different watch case sizes and they're fairly sturdy. I was pressing a watch back together and the back didn't want to snap into place, so I pressed a little harder, breaking one of the plastic dies, but the watch was fine...I ordered some aluminum dies for difficult watches, but the plastic ones work in/on most cases. It's an investment I'd make again.
