Collection: Watch Measurement Tools

Dragonfly Technology. Every sound counts.

Each of the Accuracy tools are made of an ultra sensitive sensor which is capable of detecting every single vibration in the movement of a mechanical watch. Each of these small vibrations is converted into an audio signal, highly amplified, digitalized and transmitted to the device where every second, complex algorithms process tens of thousands of data.
