Construction & package details
What this choice changes
Support the assembly rather than gripping the spring alone
The Bergeon 7995 positions a balance-cock with its balance spring during corrections. The seller describes this arrangement as intended to avoid contaminating the oil on the staff pivot. That explains the specialized support role: it holds the assembly, rather than gripping a bare hairspring or supporting the outside of the whole movement. No universal contamination-prevention result is established.
Plastic and metal are listed, without an exact part-by-part material allocation. One support is itemized. Confirm the balance-cock contact, spring clearance and access needed for your movement: no complete assembly-fit list or usable receiving clearances are supplied.
Compare the Bergeon 4072 when the requirement is a hairspring-holding pin vise, or the 4040-P when support around an entire uncased movement is needed. Neither is automatically a replacement for this balance-cock support.

Questions before you choose
Why choose this instead of an adjustable movement holder?
The documented contact is the balance-cock and balance-spring assembly, rather than the outside of an entire movement.
Is it the same as the Bergeon 4072 pin vise?
No. The 4072 is described for holding a hairspring; this 7995 supports the balance-cock/spring assembly.
What should I check for my balance-cock assembly?
Confirm the support contact, clearance around the balance spring and access required for the intended work. The listing gives no complete fit list or receiving-clearance dimensions.
