Watch Tuner Lite for Android

I tried this on a variety of watches. I tried watch crown to Android microphone. I tried wired iPod microphone. I turned sensitivity up and down. Noise cancelling on and off. I could not even get a remotely accurate measurement of beats per hour. I get too much noise or no signal. Two days of fiddling. Also does not work even with the case back taken off of a noisy watch.

I was a little bit skeptical before I got it, but it turned out to work well. Of course, it is less accurate than a Timegrapher for $100+, but it gives you excellent results nevertheless. The main hint is to put your watch and the mic into a box (preferably with thick walls), so it will catch far less noise than in an open environment (I used my Bose headphones case for that), and keep your phone outside the box to read the measurements.

While learning about how to regulate my mechanical watches, I game across this app. Buying a dedicated timegrapher seemed impractical. I used it to regulate the 7s26 movement in my Seiko SKX013. At first it gave me some strange results, but after playing with the microphone sensitivity it was reporting roughly what I’d been observing. It worked well using the built in microphone on my Android XS about 1 cm from the case (with case back on). I had the phone and watch on a desk on a mousepad in a very quiet room. I think a help screen would be nice, but after fiddling with it, it’s pretty straightforward. This combined with Marc’s video on how to regulate a movement on the Long Island Watch YouTube channel were extremely helpful.

This app may be OK for a watch. I thought it would work also for a grandfather clock, but it isn’t. The app collects a certain number of ticks, and for a watch that’s a minute or two. For a tall clock, with 3600 beats per hour, this takes a l-o-n-g time. Not a good buy for clocks :(

This worked exactly as expected. Like reallly really well. It’s obviously not a timegrapher, but if you use as directed you can set a Seiko 7s28 to within +\- 5 seconds/day or better. I hid in a quiet closet away from my loud kids and opened the caseback, set my Android wired earbuds mic on the case, and got a signal no problem. The measurement is way more accurate than your ability to push the 7s28 regulating lever, so it takes a few tries. I bought this thinking it might be a bust. It was so super good this is the only online review for anything I’ve ever written. If it’s not working for you, you’re not following the directions. The accuracy I have on an SKX007 is (for now) within 2 seconds/day and it feels like a million bucks because of it. Great job!
