I wear an automatic Seiko. I like that I don’t have to worry about a battery staying charged/wearing out over time. I just have to take a second every couple weeks to set it forward to account for it losing a few minutes. Another factor is when I looked at the smart watches that were available last time I got a new phone and they were all very large and I have small wrists which I don’t want to emphasize. My current watch fits well.
I would like to get a bracelet or something that tracks biometric data but from what I saw when I was investigating those is that they all have watch functionally as well and I don’t want to wear two watches.
