What this choice changes
The Bergeon 4040-P is for supporting an uncased movement. Its reversible and extendable construction provides an adjustment option within a seller-stated 20–43 mm movement-diameter range. Choose it when the support around the movement is the purchase requirement, rather than a holder intended to resist case-back opening torque.
The seller describes the synthetic material as non-marring, a relevant consideration when choosing the surfaces that contact a movement. Its 20–43 mm movement range also gives a starting comparison with the Singcci pair, whose capacities are not listed. Check the contact locations and clearance around projections as well as diameter; the material description is not a guarantee against marks in every setup.
This package contains one holder. It is a different offering from a soft cushion and does not supply a hand press, remover or case opener. If you need a complete hand-setting arrangement with labeled bases, compare the AGULIUM press separately.

Check contact locations and projection clearance as well as movement diameter.
Use movement dimensions for this comparison; whole-case diameter is a different requirement.
Its documented role and 20–43 mm range concern the movement. A case-holding fixture is a separate product category.
It provides a reversible, extendable holding arrangement, whereas a cushion is a support surface without the same adjustment.
That set supplies two differently sized screw-adjusted supports. This Bergeon supplies one reversible synthetic holder with a stated movement range.
