I needed to put a watch back together and the plastic boot that fits into the die actually stripped and the metal bushing on the stem that twists down actually pushed through both the boot and the die and put a circular dent into the middle of the case back.  So now I'll be tossing this into the trash since my new lever-type press is arriving in the mail today.  Don't waste your $30 on this piece of junk, you could end up trashing an $80 watch like I did.
