Good luck trying to counterfeit one of these nano-watermarked Swiss watches

Now, however, a Swiss startup named Nanoga has developed an innovative nanoscopic watermark intended to help luxury watchmakers distinguish their devices from counterfeits using only an ultraviolet flashlight.

Nanoga s method, dubbed DNAwatch, is impossible to detect with the naked eye, according to a press release from the startup.

Specific areas along the layers are then activated to respond to ultraviolet light.

Replicating the DNAwatch watermark is as complex as making a counterfeit Swiss 50-franc note, Nanoga claims.

Nanoga is based at the École Polytechnique Federale de Lausanne, a Swiss research institute that specializes in physical sciences and engineering.

This would mean even classic watches could be watermarked without affecting the watches aesthetics.
