Lepsi Watch Scope (Review) – Watch Analyzer In The Palm Of Your Hand?

Today we are gonna look at a watch analyzer to read how accurate is your movement from a Swiss company called “Lepsi“. But this is no ordinary watch analyser as it fits in the palm of your hand easily and I already can think many situations where this could be really handy.

So the company Lepsi has been making this watch measuring device since 2016. I remember that I saw it on a couple of watch blogs and videos, but somehow it didn’t catch that much interest in the watch world as there isn’t a lot of information for watch people about this in my opinion amazing device! Lepsi actually are the first ones that made a watch analyzer this small and everything is made in house in their shop in Switzerland, so it is a 100% Swiss Made product!

The Lepsi Watch Scope comes in a very nice small wooden box. Inside you will find the Watch Scope itself and a 3,5mm high-quality audio wire. The device is very well packaged and when I took it out it feels like a solidly built product and not some China made crap that you get from eBay.

The Watch Scope is basically a little round case that holds a microphone, which – through a jack plug cable – connects to your phone or any device that uses iOS, Android or Windows 10. The Watch Scope is made of high-grade aluminium that has this black coating. All the markings and Lepsi logos are laser etched. The top where you place the watch has this soft material that looks like carbon fibre and in the center, you can see the microphone hole. That is the top part where you place the watch. The diameter is 36mm, height is 12mm and the weight is only 10g so you can see how small it is!

So how do you start measuring the accuracy of your watch? Well at first you will need to download the free app on your phone/tablet (works with iOS, Android or Windows10). The app is called Watch Scope. Then you plug in the audio cable into your phone and the second end into the Watch Scope. There will be a setup process, but it is pretty straightforward and fast.

When you’re all set, open the app and click the play button at the bottom of the screen. And then the counter on top will start counting back from 18 seconds, the pulsating symbol appears in the centre of the screen which shows that the device is picking up the movement ticking, and before the seconds are up the result will appear in seconds per day. You can switch the view between sound or graph (I choose the graph as I understand it more) to see how the performance differs while Lepsi changes into a continuous analysis when the 18 seconds are up. When you want the measuring to stop just tap the stop sign at the bottom of the screen. In settings, you can choose between “standard” or “watchmaker” mode. “Standard” only gives you basic info of your watch’s accuracy while “watchmaker” mode display further metrics like rate variation, beat error or amplitude. I choose the watchmaker mode as it shows a more detailed report of the watch accuracy.

A very handy feature with this app is that you can clock the notepad-and-pen icon on the top right corner of the screen. This allows you to save the results. You can measure your whole collection and store each watch’s data in the app. Later you can edit, ad photo of the watch, update or perhaps delete these results. In the app, you also have other features. At the top we have “Quick measure” but we already talked about that. The next one is “Magnetism detector”. If you click on it the on-screen description tells you what to do to make the feature work. You can also download a separate free app with the same function if you want to use your phone as a device to detect whether your watch is magnetized or not.

The idea is simple, iPhones have built-in compasses and those contain a magnet. The software uses that magnet to detect if the object you hold close to it also has magnetization or not. To calibrate this feature, you need a piece of magnet (any magnet will work fine). You have to move it across the screen without touching it and where you see the highest result is where the compass located on the phone. Tap the screen there, the app saves the spot and from now on once you move your watch over this area the app will tell If it has magnetization or not.

The third menu is the “Collection” feature. As I mentioned above, you can save the measurements of your watch and store it here. You can name your watches, upload their own photos and update the measuring whenever you have the watch serviced or experience change in its performance.

Measurement report, the fourth point, creates a pdf of the watch’s diagnosis. You can either print it from your phone directly or email it to someone. The fifth and sixth features are in every app: “Parameters” which is another word for settings and “Help”. Well, that is self-explanatory.

Overall this is a very good thing to have. As it is very handy to know when you need to service your watch or maybe just adjust the accuracy or maybe check if the watch is magnetized. Also, it is very helpful when buying watches, especially vintage ones. You can go and check the watch out and even measure the accuracy. Of course, I took it to my local watch geek meetings and the Watch Scope was the star of the meeting and I ended up checking everyone’s watch accuracy.

If you would like to invest in a Lepsi Watch Scope the price is 249 CHF (€ 219). And that for some may be the biggest downside of this as you can buy a Seiko for that money, but if you are constantly buying watches or maybe you review watches like me or you are a watch dealer who buys watches every week to sell, this is a very handy thing to have! It shows very accurate readings and I tested it by going to my watchmaker and he tested the exact same watch (Spinnaker Dumas) we had here for the test and the big timegrapher showed the same results as this little device that is maybe 100 times smaller and cheaper.

Lepsi also has a bit bigger device called Dock which also measures watch accuracy, but with more precise readings and a lot more features like automatic watch demagnetization, wireless connection (no wires) and much more. They also sell their own watch winders, watchmaker toolkits and other products.
