Never-late Watch

Short description: It's a watch that makes it so you're always on time.

A bit more detail: Watches nowadays are tied into smart phones and GPS systems, and could adjust themselves to ensure that even if you're usually late to things, you're always on time.

Okay, okay, here's how it works: Your watch always knows what time it is. But the time that it SHOWS doesn't necessarily have to be the same time. Your watch is connected to your smart phone, and therefore has access to your appointments. Thanks to GPS, it also knows when you're traveling and when you've presumably arrived at an appointment. If you're habitually late, it will cause reported time to run a bit faster in advance of your appointment, so that even if you get there five minutes “late”, you've really arrived right on time.

But what about for things that aren't in your calendar? Not a problem. Nobody schedules things for, say, 2:36. If you are traveling for a period of time, and then stop moving at 2:36, the assumption is (taking into account your previous degree of punctuality) that you were six minutes late for a 2:30 appointment. If that's a general pattern, the watch will eventually tend to run about six minutes fast.
