Watches

For me personally it is 3 folds.

1. it is guaranteed to "go bad" and need adjustments every 2 months, sometimes less than that
2. you can't even set it whenever you want. You need to adjust past 3am first and before that, you need to figure out the am/pm on your watch. It's annoying
3. because of #2, you can't just go straight to adjusting the date and call it a day. You always need to make sure the am/pm is correct. It is always a 2 step process, never 1

All these combined with the fact that I'm quite "date-sensitive" means that I don't need the date that much. I need it the most at work and I have my work computer for that, and when I'm off work, I would remember what date it was while I was working just a few hours ago and know without having looking at my watch.

The fact that most modern dress watches have date annoys me.
