At the EPHJ trade fair, the Acrotec group unveiled a technology enabling the development of a fully industrialised non-magnetic regulating organ (French acronym O.R.A.). This major advance is based on the group’s ability to coordinate, assemble and produce a movement’s most sensitive components from materials with very low magnetic sensitivity, such as silicon, metallic glass and certain ceramics.
Thanks to the group’s unique synergies, this technology is now available to the watchmaking market without compromising on quality or performance. The O.R.A. is produced and assembled according to each customer’s specific plans. It includes all the key components of the regulating organ – the balance-spring, balance and balance-staffs – machined to micrometric tolerances and with finishes equivalent to burnishing. The degree of precision achieved guarantees optimal chronometric performance and increased stability in the face of magnetic disturbances.
Six Acrotec entities collaborate in producing this solution: Sigatec, KIF Parechoc, Mimotec, Petitpierre, STS and Acrotec R&D. Final assembly and customer relations are handled by Sigatec, ensuring a one-stop shop approach, true operational efficiency and total confidentiality.
Environments saturated with electromagnetic waves pose a growing challenge to the regularity of mechanical watches. A complete, reliable and industrialised non-magnetic regulating organ is becoming a key competitive advantage. Acrotec’s offering is aimed at both established companies and independent brands wishing to integrate this technology into their product strategy.
