    Hello all.

    Recently acquired some watchmaker tools and found complete set of compression rings for Breault's 30-second crystal changer from New Richmond, Wisconsin. Pat. pend.

    Sorry for no pics but google search shows what they look like. Basically they are a set of 11 rings progressing from small to large with a gap that looks to fit in some pliers type handle that may be specific in design. Or might be able to squeeze gap with normal pliers.

    Does anybody know the tool, how its used?

    The May 1959 edition of the "Journal of Modern Watchmaking" has a blurb in the upper right of page 12 respecting this brand-spanking new device:

    It looks like any old pair of pliers could be used to squeeze the crystal holders in order to reduce the diameter of the plastic crystal so it could be slipped into place, when the pliers are released the crystal would pop back to normal size.

    Much thanks vclip. The pic sure does show a normal pair of pliers used. Even the cheap ones at that.!

    A similar tool was offered here in Germany in the past. It was a set of "luxury" circlips and a pair of pliers.

    I have a set made by Seiko. It consists of grated split rings that fit an ID in a pair of special locking pliers. By far, this is the BEST system I found for removing watertight crystals that can be reused. Of course, excellent for inserting new crystals.

    You often see the pliers made by any number of makers on ebay sans a complete set of rings. But the rings are easily made on any Sherline lathe or mill or larger.
