TechSpot reports that the watch [3]was based on the Casio Mini personal calculator first released in the early 1970s — even offering a keypad using the original fonts (with numbers separated by grid lines):
> Even the mode button, colored red, is a nod to the calculator's power indicator. The watches' calculator function can add, subtract, multiply, and divide up to eight digits. As for watch functions, you get dual time, an alarm, stopwatch functionality, and more...
>
> Casio's [4]original personal calculator debuted in 1972, and cost $59.95. It featured a six-digit display, was a quarter the size of its competitors, and cost just a third of rival products. The calculator was an instant hit for Casio, selling a million units in the first 10 months on the market and more than six million units over the span of the series.

This Brings me Back to the mid 1980's (Score:4, Informative)
When I started at UCLA in 1985 for my first degree I did not have a lot of extra cash, so I got a used calculator watch as my first calculator. It worked quite well for the limited calculations I needed that first tri-mester. Alas, the watch battery died the morning before my Chemistry Final and I hurriedly bought a Sharp EL-506P Scientific Calculator for the final. I still have it. For the 2nd Degree I tried out an HP-41C that had been given to me. Used it for the Semester and during the last final for that year I accidentally dropped and broke it. Bought a HP-48G during Christmas break and have used those ever since.

When I was at UCLA, calculators were prohibited in chemistry exams. Slide rules were allowed, and I believe that the exam pages had a log table either as an extra page, or printed on the back side.

A couple of years ago I picked up a Sharp EL-5100. The screen has sunburn but you can buy replacement LCDs. It wasn't too hard to fit the new LCD, used some UV glue to to attach the plastic cover without any bubbles. The PCB need a bit of cleaning and solder mask replacement where the batteries had leaked.
It's a great calculator, and the slide action on the case is immensely satisfying. I'm happy to have fixed it too, saved from landfill.

And then you came to the realization that the buttons are small and awkward to push, and immobilizing your watch hand while you push the buttons with your other hand is less good than just pushing buttons on a pocket calculator.
By the time I went through gradeschool in the 90s, they'd given up on the "calculators dull the mind" dogma and handed out school-approved calculators for math class. There were still arithmetic drills, of course. But after the obligatory speed test at the start of math class, in which Mrs H would hand out mimeographed sheets, face down, containing 30 arithmetic problems, say "Go!" and give a special sticker to whoever go the most right in 90 seconds, she would hand out the calculators and proceed to the real meat of the curriculum where mathematical reasoning was the objective and arithmetic accuracy was important but also incidental.

Your text below seems to indicate otherwise. The drills you mention are precisely designed to offset the negative effects of going 100% calculator.

Calculators had become an established tool. Students needed to learn how to use them too. However the drills avoided a phenomena called equipment dependency.

I've seen what happens when students don't drill their multiplication tables and it isn't pretty. Kids with parents who drilled them anyway have a significant advantage in math and science. It shows up as early as long division, but really becomes apparent when they st
Too bad it doesn't come with digital invaders (Score:4, Informative)
Some of the Casio watches back then had a game on it called digital invaders where numbers would "invade" from the right, and you had to match the numbers streaming in to destroy them. There is a standalone version on Google Play: [1]https://play.google.com/store/... [google.com]
I've also seen other versions on the web... There may be an iOS version as well.
Anyways, those watches were highly prized as they could provide much needed always available boredom relief back before cell phone games. I'm surprised that casino's current models (or this one) do not host the game. It would be a trivial cost and effort to add it on with today's technology.

It does all the things you'd expect of a scientific calculator.
