Accuracy boutique edition

The new measurement tool for mechanical watch lovers.

The first in everything.

The ONEOF Accuracy boutique edition is the first ever connected tool capable of measuring and demagnetizing a mechanical watch at once.
It was designed in unique partnership with famous Swiss watch brands to deliver the most efficient solution to watch magnetization – a powerful and easy-to-use tool able to solve the problem directly in boutiques.



Magnetization: the main watch illness.

Strong magnetic fields are everywhere, generated by commonly used objects such as speakers, motors, electronic devices and even leather goods. Very few brands offer watch movements insensitive to magnetic fields. The main symptoms of a magnetized watch are generally a low amplitude of the balance wheel and, more critically, an important loss of precision up to several minutes per day.




Amazingly powerful.Absolutely plug & play.

Other demagnetizers available on the market require to be plugged into the mains power supply using a variety of dedicated adapters depending on the country. Accuracy boutique edition is based on the commonly used and cross-platform USB standard and requires no battery or power supply.
The integrated Temperature Compensated Crystal Oscillator (TCXO) ensures a precision of measurement lower than +/- 0.1 s/d.
