Whats new in Kello v2.49

6 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.

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.
