User reviews

Very handy app

This app excels at two things: 1. Tracking the offset / accuracy of your mechanical watch, 2. Helping you to easily set your watch.

As far as tracking the accuracy of your watch, I really like the ‘time was set’ option so that you don’t have to start a new timing run just because you update the time of the watch.

As for setting the time, I really like the atomic clock with the loud ticks and beep at the top of the minute, and find it to be a very thoughtful feature.

I recently regulated my Seiko automatic watch using TG, and it's very satisfying to be able to see the fruits of my effort using this app.

Big thanks to the developer.
