I was visiting my nephew recently and he tinkers with watches. He did a few tasks for me and we adjusted a few bands. Just for fun we put my Invicta on the timegrapher and I was very surprised! Has a beat error of +3 seconds a day from the factory with no adjusting. Amplitude was a little low at 202 but all in all not bad for a low cost watch.
FYI it has a Miyota 9215 movement (a part of citizen) and the movement was designed around 50 years ago.
