Seiko DATA-2000 =============== After long decision process I finally have got the DATA-2000 smartwatch (just like these ones [1], sans the manual). Well, it's a device from 1980s so they are not as "smart" as modern things called "smartwatch". They are digital watches that can show time, data (day in a month, actually) and which have (rather basic) stopwatch and alarm functionalities. That's almost all that they have. Except one special function: they have two data areas called "Memo A" and "Memo B". These can be used to store texts (up to 1000 characters long) which can be viewed on the watch's LCD screen. To enter the text one has to use an external keyboard, however. It seems to be crazy and impractical today but it must be almost sci-fi technology when it was new. I have got them for practical reasons - I don't like to carry/use the smartphone (or PDA) when doing shopping. And I don't use modern smartwatches (I have terrible experience with the WearOS ones and my Pebble just have entered another round of issues). Thus these ones have been looking like a good solution - a wristwatch which can carry my shopping list or To Do list (the text can be arbitrary so it's compatible with the todo.txt !). Mine DATA-2000 aren't in perfect condition, of course. There are some dead pixels on two of characters in the bottom left corner. Actually, one line from the letter matrix is missing in both characters. I hope that this issue will not continue to expand. The only other functionality I found so far is the calculator. But it is very limited (it can do just + - * /) and it only works when the external keyboard is attached (there is no way to enter the numbers without this keyboard). Surprisingly, LCD contrast seems to be good for normal use (the screen is not backlit, however). So I think I will try to use them during my net shopping run...
