Surprisingly effective

After a full service center overhaul of my Omega Seamaster I decided to use Twixt to check the accuracy. Even though my watch had just been serviced Twixt measured that it was gaining just over 6 seconds per day (the threshold for chronometers). I took this info to the service center and they were able to get the gain down to about 1.3 seconds per day. Without Twixt I wouldnt have known my watch was out of spec and would have just accepted poorer accuracy than necessary.

The app itself is clean and easy to use. I didnt expect it from just photographs of the watch face but the accuracy is impressive: it matched the Omega service centers measurement exactly.
