Watchmaking

With over 35 years' experience supplying and manufacturing micro-components for the watchmaking industry, we produce very small, complex turned workpieces used in watch movements for the luxury watchmaking sector. These machined watchmaking micro-parts are then finished with surface treatments and/or finishing operations according to your requirements.

Over time, the technical and aesthetic requirements of Swiss watchmaking have become more demanding. At Polydec, we are experts in managing these two aspects in our daily work, from machining your watchmaking micro-components to performing finishing operations.

Our skills

Precision turned watchmaking components includes, for example:

  • milling
  • drilling
  • thread-whirling/tapping or threading
  • hobbing

These operations are carried out simultaneously on the precision turning machine.

The functional characteristics and the aesthetic aspect – key elements in the luxury watchmaking industry – are achieved using different treatments and/or finishing operations:

  • heat treatments
  • micro-polishing
  • rolling
  • polishing/black polishing/mirror polishing
  • galvanic treatments: nickel plating, gold plating
  • bluing
  • sand-/ micro-blasting
  • decorations (sunray polishing)

We carry out some of these processes on our own premises, while the rest are subcontracted to qualified partners with whom we work closely.

Customised services on request
To complete the rigorous controls during production (SPC), our team of engineers has developed automatic machines for measuring watchmaking micro-parts, enabling operations such as:

  • full dimensional inspection
  • sorting into categories according to dimensions and/or tolerances

Other innovative technical techniques can still be developed, contact us!



Our culture

The rigour required by the IATF 16949 automotive standard in the control of our processes has enabled us to expand our business into the watchmaking market, where precision and excellence are core values.

All our business-related tasks are controlled, documented and centralised by an ERP software, developed in-house. This computerised control enables us to efficiently co-ordinate all our manufacturing processes and to supply parts which are compliant in terms of quality and lead times.

Moreover, particular attention is paid to the well-being and respect of our staff, our partners and the environment. This philosophy is an integral part of our corporate culture.
