What this choice changes
One rubber ball for friction-contact opening
The Bergeon 8008 is a single rubber opener ball for a handheld friction approach to rotating case backs. There are no interchangeable claws or grooved dies to select within this pack. It is the simpler one-item format to compare when the back offers suitable friction contact; it does not guarantee that a tight or unsuitable cover will turn.
The YUYTE kit provides a different friction setup with a handle and nine interchangeable silicone contacts, while the YWBL-WH wrench uses three metal engagement points. Choose by the actual contact your back offers and whether you want one ball or a component assortment. None of those tools supplies the seam-lifting action of a snap-back opener.
The selected pack contains one black ball bearing the 8008 marking. The title gives a 65 mm diameter and the description gives 67 mm; the structured 2.56-inch outside dimensions are approximately 65 mm but do not settle the disagreement. Confirm the exact ball size if it matters to your grip or storage. None of these outside dimensions is a compatible watch-case range.

Check the working requirements
Contact type
Check that a friction approach is appropriate for the rotating back you intend to work on.
Size-sensitive purchase
Ask for confirmation if the precise ball diameter matters; the listing gives both 65 and 67 mm.
Limits to keep with the choice
- Title diameter 65 mm and description diameter 67 mm disagree; exact ball size needs confirmation.
- Friction does not guarantee opening or a nonmarking result.
Questions before you choose
When would the YUYTE kit be more useful?
When you want a handle and interchangeable silicone contacts rather than one handheld ball. Both are friction approaches, not interchangeable-claw wrenches.
How large is the ball?
The title says 65 mm and the description says 67 mm. The separate 2.56-inch dimensions are approximately 65 mm, but the exact outside size still needs confirmation. A ball diameter does not establish a compatible watch-case range.
Can I use it to lift a snap-on cover?
The documented role is a rubber friction opener for rotating backs. A snap-on cover needs an appropriate seam-opening format instead.
