Some collectors might have experienced it: sending back your beloved mechanical timepiece to a service center, waiting for 3 or 4 months for it to come back, and learning that in fact, a service was not really needed or that the watch was simply magnetized. However, there might be a solution, for home-testing. ONEOF Accuracy measures the accuracy of your watch with real-time analytics. And there is more – the “boutique” edition will even allow you to demagnetize your watch!
This has been one of the cooler finds at EPHJ (the Geneva trade fair for watchmaking, jewelry and micro-technology – late June 2017). ONEOF Accuracy measures the accuracy of your watch with real-time analytics. Plus, if you go for the “boutique” edition, it can even demagnetize your watch.
The use of ONEOF Accuracy devices could not be simpler – you just need to plug the device into a mobile phone or tablet using the brand’s App (ONEOF Accuracy), which is available on iOS and Android. The user-friendly device measures the following data from your watch: rate, frequency, amplitude and beat error. You can save data for your different watches if you want to keep track of how these perform over time.
It is a stand-alone device, so it requires no battery. You simply need to plug it into your mobile, and it is ready, no calibration is needed. Just watch the following video.
A simple, quick test of the accuracy of a COSC certified Brellum Duobox, still operating with superb accuracy after several months (movement: valjoux 7750) – The video is slightly shortened as the process takes about 30 seconds.
The ONEOF Accuracy operates thanks to a sensor detecting the vibrations in the movement of your mechanical watch, which are amplified and digitalized in order to be processed by the device. It covers the vast majority of mechanical watches but not those with unconventional escapements (meaning that over 99% of mechanical watches will be recognized). The connection is made with the USB port, with no jack connector. Finally, a magnetic field sensor allows you to check whether your movement is magnetized, even on the standard edition.
ONEOF has now just released an even cooler device with their “boutique” edition that allows you to easily demagnetize your watch. Magnetic fields are everywhere, and they can affect your mechanical watch, with a loss of precision up to several minutes per day. A significant portion of visits to aftersales services are often simply due to magnetization and do not require other operation, other than demagnetization. Well, you can now manage this easily at home, controlling and demagnetizing your watch in less than 2 minutes. You basically just need to place your watch on your Accuracy Boutique edition and tap the “demag” button on your app. The operation often needs to be repeated with the watch in different positions to be fully efficient.
The ONEOF Accuracy devices come in sleek brushed aluminum housings, are entirely Swiss Made and, we have had the opportunity to visit the production facilities near Neuchatel. They combine great design and cool features, plus are very easy to use. There are only a few minor shortcomings to note. For a start, they only allow you to test your watch in a limited number of positions, which is perfectly fine for non-professional use. And, if you are an iPhone user, you will need to purchase an adapter from Apple (ONEOF is not an Apple distributor so it is not officially authorized to sell their products – don’t worry though, it is super-simple to buy from Apple and will be delivered within a couple of days).
Priced at just $199, it is indeed a cool accessory for watch lovers to have next to a collection. The boutique edition, at $990, is more expensive but the ability to demagnetize your watch yourself is indeed super-useful. For people with 10 luxury watches or more, this can even be a relatively interesting investment, knowing the prices of servicing at certain high-manufactures.
