What this choice changes
Choose the holding arrangement before choosing another opener
Choose this Joyzan fixture when you need a separate case support to use with an opener you already have. Its opposed blocks carry four white contact posts, with two guide rods, a spring and a threaded adjustment knob forming the holding assembly. This rod-and-spring construction is the useful distinction from the Dofover holder’s indexed screw-slide bed.
The rectangular base shows four mounting holes. Compare the base and hole layout with the place where you plan to use it, and confirm the fasteners you will need. Supplied mounting bolts and a matching pattern for a particular workstation are not confirmed.
The stated 11.8 × 7 × 7.4 cm dimensions describe the fixture’s overall size. They do not give its maximum case diameter or jaw opening. If a particular watch is the reason for the purchase, check that actual contact requirement rather than substituting the outside dimensions for a working range. The Dofover alternative provides a different screw-slide construction and a seller-stated 18–52 mm case range.
- Two guide rods and a spring provide a clear construction alternative to a screw-slide holder.
- The pictured base and mounting holes help identify the fixture’s bench-oriented format.

Questions before you choose
How is this different from the Dofover case holder?
The Joyzan uses two guide rods and a spring with opposed holding blocks. The Dofover uses an indexed screw-slide bed. Choose by contact geometry and setup requirements.
Will this holder accommodate my watch case?
Confirm its working opening and where the four posts will contact your case before buying. The stated 11.8 × 7 × 7.4 cm measurements describe the whole fixture, and the listing does not give a maximum case diameter or jaw opening. If you need a stated case-size range for comparison, the Dofover holder lists 18–52 mm.
What else do I need to open a case back?
This reference supplies the holder. You still need a separate opening tool that matches the back: the seller’s use text describes holding the watch and then using an opener to unscrew the cover.
