Micro-CT and 3D Modeling Unmask Fake Luxury Watches

Published on May 04, 2026 | Translated from Spanish

High-end watch authentication has taken a quantum leap thanks to the combination of Micro-CT and 3D modeling. In a recent forensic analysis, a suspicious luxury watch was subjected to tomographic scanning with a Nikon CT scanner. The result was devastating: the generated 3D model revealed structural defects in the rubies and surface finishes incompatible with Swiss artisanal manufacturing, proving that industrial technology is the new ally against counterfeiting.

Forensic workflow: from Nikon CT to SolidWorks 🔍

The process begins with data acquisition using a Nikon CT scanner, which captures the internal geometry of the mechanism without disassembling it. The data volume is processed in VGSTUDIO MAX, where critical components, such as synthetic rubies and plate finishes, are segmented. By comparing actual tolerances with factory standards, discrepancies are detected: internal inclusions in the stones, bubbles in the polish, and anomalous clearances in the axles. Finally, the model is exported to SolidWorks to generate an exact digital twin, allowing experts to measure micrometric deviations that no human eye could detect.

This case demonstrates that digital goldsmithing is not only useful for designing new pieces, but also for protecting the integrity of existing ones. The ability to scan and compare a watch against its master CAD model turns each piece into a verifiable document. For artisans and collectors, Micro-CT is emerging as the definitive authentication standard, making counterfeiters, trapped between their own defective rubies and imperfect finishes, lose the game on the field of absolute precision.

What is the minimum level of detail a Micro-CT scanner must capture in a watch to distinguish an authentic piece from a counterfeit through 3D modeling?
