Lower case-Holders in adipren 5700-Z

These lower case holders fit the bed of our 5700-Z case opening tool. We mold the contact faces in adipren, a resilient synthetic material that yields under clamping pressure to seat around the perimeter of the watch case. Sizes cover 19 mm, 26 mm, and 34 mm diameters across the set.

Molded adipren contact

The body is cast in synthetic adipren. This soft compound cushions the lugs and case flanks while you tighten the vise spindle, avoiding direct contact with bare brass or steel.

Three graduated diameters

The set spans 19 mm, 26 mm, and 34 mm sizes. Choosing the diameter closest to the watch case spreads the clamping load over a broader arc of the case band.

Fit for the 5700-Z

Each holder drops directly onto the guide pins of the 5700-Z case opener base. They sit flat on the bed and stay aligned under the downward thrust of the top spindle.

Bench care and cleaning

Keep the synthetic faces free of metal filings and dried grease. Wipe them down with a dry pegwood point or a lint-free cloth before seating a clean case.
