The hairsprings that we deliver have passed the chronometry test (COSC). The highest level of the CTE (thermoelastic constant) is attained, and our manufacturing process guarantees perfect reproducibility.
Our second challenge was the development of the manufacturing technology of the mainsprings. This spring is the " reservoir of energy " of the movement of a mechanical watch.
We also carry out heat treatments and galvanic deposition on all types of substrates. In addition, we perform part finishing work (deburring, polishing ...)

We continued our work to develop spirals in three dimensions :
The manufacture of this spring is carried out in a sequence of numerous stages which consists of:
The cylindrical spiral, unlike the generally used spirals, does not swing on a plane level from front to back, but relaxes and contracts in raised rotation along the length of a vertical axis, as if it were following the thread of a screw. A second advantage of the cylindrical spiral is its completely concentric and symmetrical development.
Spherically-shaped springs are parts that have a very attractive appearance and improve isochronism when compared with flat spirals. Our parts have been installed in a prestigious Swiss watchmaking company's high-end movements.
We propose a variant that is spiral colouring. The spherical and cylindrical spirals can be coloured without modifying their physical and mechanical properties: purple, golden yellow, etc.
Spherical spring used in fine watchmaking
To overcome the magnetic sensitivity problems of nickel-based alloys and increase the impact resistance, we are working on new paramagnetic alloys.

The material used to craft our barrel springs is Nivaflex.
All the manufacturing steps have been validated by Metalab. Our springs were first tested internally. We then supplied various Swiss watch manufacturers who validated our production. The productivity of our mainsprings are exceptional. For all inquiries regarding mainsprings, please complete the form below:

Bulk polishing on 20AP steel
We produce the following finishes:
– Fine polishing of parts (including fine teeth)
- Chemical polishing on coppery alloy
- Chemical deburring of the steel
- Elimination of oxidation
We have strong experience and know-how in the processing of sintered materials such as micro-magnets.
Our company can provide you with the following additional services:
- Adhesion tests: thermal shocks, peeling
- Characterization of the deposited layers: distribution, morphology of the layer, thicknesses
