The physical equipment
Construction & package details
What this choice changes
Check the crystal construction before choosing the lift
The Bergeon 4266 uses a gripping/compression lift format to remove and insert a crystal. For its stated application, the seller describes access without disassembling the watch, including crystal replacement or access to the hands. The restriction is an “unbreakable” crystal without a tension ring. Confirm that construction for the exact watch; it does not establish fit for every mineral or sapphire crystal.
The stated metric range is 10–45 mm. Match the crystal geometry and the absence of a tension ring as well as size; diameter alone does not establish suitable construction or fit.
The core item is the metal lift tool. A platform is pictured, but its separate package allocation is not itemized, so confirm that accessory if it is essential to the setup. Compare the Keenso pump for its different one-piece-case pressure-removal role, or a case-closing press for the separate operation of reclosing an external back.

Check the working requirements
Crystal type
Confirm the actual material, construction and tension-ring condition against the seller’s restriction.
Accessory need
Verify the pictured platform and its receiving arrangement if your setup requires it.
Limits to keep with the choice
- Use the explicit 10–45 mm metric range; the additional parenthetical notation is ambiguous and does not establish another converted range. Crystal-material fit and damage-free operation are not universal; the pictured platform’s package allocation needs confirmation.
Questions before you choose
Will it work with a tension-ring crystal?
The seller expressly specifies a crystal without a tension ring. Do not assume that restriction can be ignored.
Can I use it for any mineral or sapphire crystal within the size range?
That material compatibility is not established. The seller uses the restricted “unbreakable crystal” wording; confirm the exact intended crystal type.
How does it differ from the Keenso pump?
The 4266 is a gripping/compression lift. Keenso describes a pressure-removal pump for one-piece cases, with its own nozzle requirements.
