In-house movements
At our Albuzzano facility, we produce the components of our movements with the highest precision
CAD / CAM design
Using 3D CAD software, the movement is designed down to the smallest detail. Everything is meticulously controlled, with tolerances in the order of microns
Once the design is complete, the parts to be produced by Oisa 1937 – mainly bridges and plates – are extracted. The programmes that allow the CNC machines to operate are created using further software and extensive experience
Production with CNC machines
Machining always begins from a brass bar (a specific alloy for watchmaking), from which the required component is obtained. The machine carries out the machining using specialised tools.
Throughout the entire production cycle, the parts produced are inspected with sophisticated instruments (video CAD) and manual gauges.
Decorations and engravings
Once production is complete, the components are sandblasted and individually decorated. The more specialised processes are carried out using a programmable centre, which allows unique effects to be achieved thanks to the operator’s skill. Some decorations are our exclusive creations, unavailable elsewhere.
It is also possible to engrave inscriptions and logos directly onto the components by laser.
Assembly and testing
After decoration, the components move to the assembly workshop, where our watchmakers assemble the movement. Pre-assembly is carried out on bridges and plates for elements such as jewels, using specific tools. This is followed by full assembly of the movement, which is then tested using a timing machine: the parameters obtained must fall within predefined limits, otherwise the movement is checked again.
If everything is compliant, a dial and test hands are fitted to verify that the movement functions correctly for 60 hours at full wind.
Movement coding
The laser-engraved data matrix on the movements ensures that each piece leaving our facility is unique.
This code not only simplifies production monitoring, but also provides detailed information about the manufacturing processes – a traceability system that allows rapid and precise access to the movement’s specifications.
