This is of course a matter of personal taste, but:

I usually set my watch a few minutes fast on purpose. I just use it to get an approximation of the time: "oh, it's nearly 5"

When I need the exact time I look at my phone, and naturally that's where my calendar reminders and such live as well. So I'm not missing any appointments if my watch is off, and if I did rely on my watch I'd be a few minutes early.

The two work well in tandem for me.

Of course, I also know lots of watch owners who prioritize accuracy from their wristwatches. If I was one of those people, I really couldn't imagine wanting to deal with a mechanical watch. They are wonderful, wonderful little machines and it's a miracle they're as accurate as they are... but, they are not as accurate as a $10 digital watch.
