And even many digital clocks are still dumb devices that need to be manually synced. Such as most kitchen appliance clocks.
All of those clocks have drift and most of the wall ones are wrong by several minutes. We're also talking the drift of 1 hour over the course of 6 months. or .32 minutes a day, or 2.3 minutes a week. Most clocks will be drifting that much on weak batteries or grime if they're not quartz or digital.
Your fancy watch likely isn't on time unless you have only one, or you have auto-winders on all of them. And you're not going to miss an appointment because your Patek is off by .32 minutes a day 2.3 a week.
If you cared about accuracy you'd have a network clock synced to an atomic clock, oh wait, you do, its in your pocket. People wearing watches for fashion aren't using them for their calendar appointments or because they don't want to be late for an appointment with the King.
Also, 5 minutes of drift is still very noticeable for people. You don’t need NTP for that level of accuracy but you do need the clocks not to adjust their time zones by a minute every day.
