Patrick_y introduces the ONEOF accuracy testers, a new line of consumer-targeted devices designed to help watch collectors monitor the performance of their timepieces. His post highlights the frustration many collectors face with limited diagnostic tools and the often lengthy, expensive process of sending watches for service. Patrick_y explores how ONEOF aims to bridge this gap, offering solutions from basic accuracy checks to professional-grade diagnostics that were previously inaccessible to the average enthusiast.

Do you have multiple watches? 

"Yes, I do!"

Are all of them running perfectly? 

"I have a Jaeger-LeCoultre Master Ultra Thin that runs fast and a Patek Philippe that seems to run fast.  I wished that I had some kind of a tool to measure the accuracy of my watches and a diagnostic tool to identify potential problems!  The dealer has been NO HELP AT ALL!  They just want me to send the watch back to service which takes months and costs hundreds to thousands of dollars.  I've tried the compass test to see if the watch is magnetized, but the test was inconclusive."

We finally have a watch tester targeted at consumers.  ONEOF is a new tool that comes in three different levels targeted at watchmakers, boutiques, and collectors. 

I haven't tried this new tool yet, but I'm excited about it!  Apparently you connect it to your Android or Apple iOS device, it connects to an app, and you can monitor accuracy of the watch in various positions. 


Accuracy ^2 is the Collector's version.  Starting at a price of $320 USD (before taxes), it's a small pocket-sized sensor that you rest the watch on and it transmits data to your phone or tablet.  You can then see the accuracy of your watch! 

Accuracy Boutique Edition is intended for boutiques and collectors.  Starting at a much higher price of $1270 USD (before taxes) it provides more information and a Demagnetizer feature.  The sensor on this version is also sensitive as it uses a special microphone for exceptional accuracy, especially on thicker and denser watch cases that may inhibit the sound.  I'm surprised that even large watch dealers don't have such basic equipment.  The largest Authorized Dealer of high end timepieces in my city doesn't even have any sort of accuracy equipment or even a demagnetizer!  Boutiques ought to be better equipped! 

Accuracy Professional Edition is $3330 USD (before taxes) and it's for watchmakers and the seriously afflicted collector.  This is a professional level machine that can measure the accuracy of the watch in all the positions.  It will provided much greater detail of the operations inside the timepiece including oscillation inconsistencies (you see them as spikes or dip in the chart), amplitude, and more than what I can fully understand.  Large stores and watchmakers should have this tool!  And the serious collector would benefit from this tool. 

It's great to see these machines come down in price over the years.  Even today, the Witschi machines cost thousands of dollars (and require some maintenance to keep the calibration perfect) and it's just not feasible for the average collector to get a Witschi machine.  There are inexpensive demagnetizers on the internet that aren't specifically intended for watches and sometime do more harm than good!  I'm glad to see we have an easy to use solution with a promising User Interface now available for collectors! 

I also expect retailers to have these kinds of tools at their stores in the future!  These kinds of tools are very beneficial for clients and retailers should make this small investment to add value to the client experience!  I've met many young individuals who've decided to give up on mechanical watches and go towards smart watches because the retailer experience was very transactional and not satisfying.  I'm going to mention this to my retailers the next time I see them! 

Thank you for reading my post!  I always like to know how healthy my watches are, so this was something that caught my eye!  As always, I read all of your comments, let me know if you have any thoughts.  If any WatchProSite member already has been using one for a while, please share with the group! 




The picture above shows the Accuracy ^2, the collector's version at $330.  It's quite comprehensive, it charts the amplitude and tells you quite a bit about the operation of the watch! 








This is the $3330 USD professional version.  This has got a lot of detail!

Compared to the basic set up. You can buy a demagnetizer. Simple to use.

I have it and it works fine. The pro is definitely ease of use light and portable... If it's for a home usage a Timegrapher will do !

I wasn't familiar with this Timegrapher device. I have met two individuals who bought inexpensive demagnetizers on the internet. One of them said it didn't solve the problem (so that means either the watch wasn't magnetized, or it was but the demagnetizer wasn't able to make it work any better). And another individual says that the demagnetizer definitely made the watch significantly worse (I don't know how this could happen, but the individual is adamant and is somewhat qualified to make the st

Thank you for introducing the Timegrapher. Today is the first I've heard of it.

Witschi won't even sell to an individual directly. Some of their distributors will, but generally they're definitely not targeting individual collectors and really watchmakers and companies. This ONEOF brand is the first that seems to be much more consumer facing.
