ONEOF Accuracy

The Accuracy Boutique Edition is the first ever connected tool capable of measuring and demagnetizing a mechanical watch at once. It was designed in partnership with famous watch brands to deliver the most efficient solution to watch magnetization and thus solve the main problem directly at retail stores and boutiques. 20 % of after-sales returns concern magnetized watches which mean both a tremendous cost for brands and high throughput times with a drop in customer satisfaction. Less than 2 minutes are required to check the rate accuracy amplitude and beat error and to demagnetize the watch by a Accuracy Boutique. 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.

ONEOF Accuracy 2 – Watch testing made easy The Accuracy2 can measure the performance of your mechanical watch like rate accuracy, amplitude, beat error in just a few seconds. The device runs with an App for Android an iOS and the complete measuring electronics are incorporated in a compact, anodised aluminium unibody of 40 x 40 x 7.5 mm. Dragonfly technoloy – every sound counts Accuracy2 is made of an ultra sensitive sensor which is capable of detecting every single vibration in the movement of a mechanical watch. No jack connector – a step ahead While other connected measurement tools on the market works only with the analog audio jack connector a brand new digital audio electronic system based on the commonly used USB standard has been developed for Accuracy2. Absolutely plug & play The Accuracy2 is a stand-alone device, which requires no battery or power supply. Plug it and forget it. It is that simple. Measure your watch in a split-second. The new Accuracy app developed by our engineers automatically detects the presence of your watch on the sensor. Just after a few seconds of initialization, you get all the detailed technical information you need in a professional and user friendly app. 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. Only few brands are able to propose 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 minutes per day. Scan your watch. The new Accuracy app uses the integrated magnetic fields sensor of your device in order to check whether your movement is magnetized. Scan your watch on every angle and see if it suffers from magnetization.
