There are many places where watch batteries are not readily available which makes the mechanical watch an important backup to the very accurate quartz watch. I recommend the Seiko 7s26 automatic mechanical movement which is affordable, simple , sturdy, and reliable. The best part about the 7s26 movements is that they can be easily regulated to better than ± 5 seconds per day.
