This tool looks fairly simple to use, but what is it? If someone could explain how it works, I'd love to know.

thanks in advance,

Jessica

Hi Jessica,

The tool is used to insert old style plastic crystals. The press squeezes the crystal from the center to make the edge small enough to fit the bezel, then the screw is relaxed so that the crystal edge will expand back into the bezel. The various black plastic parts in the box are used for different size crystals.

The most common type of crystal found today has a rim which provides enough room for the fingers of a crystal lift to squeeze. The type of plastic crystal the tool in the picture is for does not have a wide enough rim for a crystal lift to grab.

Best regards,

Greg

How about a case closing press?

Interesting. I often see tools, or tool parts, on ebay, and wonder how they work, if they're complete, etc.

People selling them often don't know themselves.

Thanks, again.
