For those of you thinking smartwatches is a new thing, let me remind you of this: The Casio Databank Telememo - DB-1000, from 1984
It had a calendar, a phone book, a notification system, a stopwatch for exercising, and it was touch-based
."50 pages of contacts with eight characters and 12 numerals per contact. All contacts are alphabetized. The watch has a search feature where the user can type the first few letters of the desired contact to look up that contact's information. Applications: Schedule and Time Table tracking. The ability to keep track of appointments or a schedule. Calculator: 8 digits Alarms: Five separate alarms Stopwatch: 59 minutes, 59.99 seconds Accuracy: +/- 15 seconds per month""Using a grid of touch sensitive lines under a protective film over the LCD, Casio was able to create a watch that recognizes letters, numbers and symbols. The user can input up to 50 contacts with phone numbers by actually drawing each letter and number on the keypad. The same goes for calculations. If you want to calculate 2+2= you would first go to CAL mode. You would see a "0" on the display, just as you would with a regular calculator. Then you simply draw the number two on the face of the watch with your finger."
Other Casio smartwatches at the time, like the TS-100 from 1989, had a built in thermometer so that it could tell you about the weather, and a world time format that would be displayed on a map ... yes, a map: http://goo.gl/iA8WW4
...and all this was 30 years ago.
