    11 things about Kello


    1. If this hand moves several times per second or appears to sweep along in a smooth, continuous motion, your watch is most likely mechanical and its precision can be measured by Kello.

    2. If you can hear a ratcheting sound as you turn the crown, your watch is most likely mechanical and its precision can be measured by Kello.

    3. Kello can automatically determine the frequency of the watch being measured based on eight of the most common frequencies used in mechanical watches.

    4. If the words "automatic" or "shock-proof" are written anywhere on the watch, there is a very high chance that your watch is mechanical and its precision can be measured by Kello.

    5. There are four simple ways to determine if your watch is mechanical and can be used with Kello.

    6. If the hand moves only once every second, it is very likely that your watch is not mechanical.

    7. Kello analyzes the precision of mechanical watches against the iOS system clock using a microphone.

    8. If the crown turns smoothly, your watch is not mechanical.

    9. If the word "quartz" is featured anywhere on the watch, your watch is not mechanical.

    10. These frequencies are standard among low-, middle- and high-grade mechanical timepieces and will accommodate the vast majority of mechanical watches produced in the past 100 years.

    11. The regularity of this sound can be measured against the more precise, internal time-signal of iOS devices, such as the iPhone, and the resulting difference in timekeeping is displayed by Kello.

    Kello Reviews


    • Don’t waste your money.

      Unable to get a signal on any watch I tried. Don’t waste your money. There are better apps available.

    • Dumb app

      Does not have signal waste of ten bucks. I want my money back!

    • Pointless

      When I first downloaded this app a while back, it worked ok. Now it just simply cannot hear the watch any longer. Don't bother.

    • Complete Garbage

      Simply the worst app I've ever purchased. Save your money!

    • Needs additional equipment or improvement

      This app is hit and miss. One of the holy grails for any amateur watch collector is a fast, reliable, easy way to measure accuracy in a mechanical watch. Kello tries, but ultimately fails with too many of my watches to merit an exceptional rating. Depending on the movement and acoustics of the case Kello typically has trouble trying to acquire a reliable signal, which if you're a dive watch collector happens annoyingly often. It's also been my experience that watches with a noisier escapement such as the ETA 2824 have a much easier time being measured than the quieter escapement of Miyota movements. I've followed the best practices in the how to guide and came up with the same result consistently.
