@Will Scarlett you broke the glass because you probably used the wrong cup holder and it was touching the glass part. There are specific sizes so that the edges of the cup sit on the metal sides of your watch and not on the glass itself.
I went to a jewelry store who had the exact same press shown in the video. They couldn't close my watch. The plastic holders/cups would bend and twist.. a total POS product. The holders MUST be metal to withstand the pressure. Not all watches are made of thin metal, you know.
+g34rfr34k Watchmakers will tell you that both the nylon and even plastic dies exert the same force as aluminum dies (without the possibility of scratching or marring) and more than enough pressure to put any back on..its the choice of dies that make a back go on (Size and Shape). If you do not understand the mechanical design of the (many types) of watch back, you can easily choose the wrong dies. Note: using nylon dies will not prevent breaking the crystal.

can you please do a giordano watch which have a smaller back and a wider front
My dyes (or dies) are made from aluminum. I'm not sure if that'll make any difference. Also, I cracked the glass when attempting to do this :(
Bought a press just like this and it broke the first time I tried to use it.
Breaks easily! Mine broke after the 1st use. The lever broke in half!
where are they made?
Move on, this video is advertising and the tool is not good. Not recommend it.
