Update: 4/10/2018
After using for more than a week I am still happy with my purchase. I have had no problems with accuracy and my watch has never completely wound down. About the only thing I do not like is that the buttons for changing the day of the week and day of the month are prone to being pressed by extreme wrist movements, but it doesn't happen to me often enough to make me dislike this watch.
But without my glasses I have to have perfect lighting to tell which day of the week and day is. Astigmatism can be like that.
Other than finding a tool with the perfect tip to change the year and day of the week, setting it was rather easy. Just read the directions.
The watch band seems nice, but I had better put mink oil on it soon.
