Bergeon 7047-PRO1 Winding Machine

Product Description

The Bergeon 7047-PRO1 is a professional winding machine manufactured by Bergeon, Switzerland, designed to test winding, date-setting, and time-setting functions on mechanical and automatic watches via the crown. It offers programmable rotation speeds (60-300 RPM) and precise torque control (5-30 mNm) for accurate and repeatable testing. Its versatility and measurement accuracy make it an ideal tool for watchmakers and manufacturers to perform functional tests and simulate aging conditions.

Features & Function

It is the result of a specific development program aimed at watchmakers and manufacturers, enabling them to test various functions on watch movements and fully assembled watches through the winding crown. The device can be programmed with up to 200 independent programs to automate testing processes.

It features precise adjustment of parameters:

Torque control: Adjustable from 5 to 30 mNm, with an automatic stop when torque limit is exceeded, preventing overload damage.

Number of winding turns: Programmable from 0 to 9999 revolutions.

Rotation speed: Adjustable from 60 to 300 RPM to simulate different wear conditions.

The device is user‑friendly. Parameterization is done via a central adjustment knob, and readings are shown on a large LCD display. The horizontally and vertically adjustable movement table ensures precise alignment of the watch crown with the winding nozzle, which is secured by three Allen screws. The rubber winding nozzle can be reversed to extend its service life. Robust components, including a stainless steel shank and handle, ensure long‑term durability.

FAQ

Q1: What are the main functions that the Bergeon 7047-PRO1 can test?
A: It is primarily used to test the winding, date-setting, and time-setting functions of mechanical watch movements or fully assembled watches.

Q2: How do I select the rotation direction?
A: The Q button on the control panel is used to switch the drive motor‘s rotation direction between clockwise (CL) and anticlockwise (CCL) to match the winding logic of the movement.

Q3: Can the machine be programmed for different testing cycles?
A: Yes, the 7047-PRO1 can store up to 200 distinct programs, making it ideal for automated and repeatable testing protocols.

Q4: What is the purpose of the torque control function?
A: It prevents damage to the winding mechanism by monitoring the resistance. The machine stops automatically if a programmed maximum torque is exceeded.

Q5: Can the machine test both bare movements and finished watches?
A: Yes, it is highly versatile. It can be used for precision testing on a bare movement or for full functional checks on a completely assembled watch.
