first wrist calculator



Litronix, primarily an LED supplier to the other vintage digital watchbrands including the first Hamilton-Pulsar digital watches. Featured here are these two experimental prototype calculator concept watches Litronix was considering for development.
But what makes this strange watch special is the unusual feature of sliders instead of buttons. Likely an attempt to improve the data entry from Multiple miniture buttons to a more tactile sliding mechanism. The sliders move over a commutator which is a pc board segment. I assume you move them to the desired number and press down for selection but it sure seems like a waste of time. I guess that's why it never went into production, huh? Maybe someone can let me know if this slider function has ever been developed into another product from that time.

  1. I have never heard of a calculator watch. Looking at the picture I can see why no one would want to buy one, let alone wear it. It looks pretty ugly. The concept is there, but most people have cell phones that have calculators in them. Cell phones look much better than that watch.

  2. This looks like way to much work to add up a few numbers. When I was a kid I had a calculator watch and i thought it was the coolest thing. The problem was the screen was small and the buttons were to small. Great concept.

  3. I have never heard of this, it is a very good and convient idea. Hopefully, not many people would then forget to bring their calculator to class. However, it is looking a little complicated to use. But a ti-89 probably looks complicated too.

  4. This invention has great insight as to what is to come for the future of nano-technology. Although this product doesn't appear to be all that impressive or highly advanced its concept shows promise.

  5. This is a rather cool novelty, but even a pocket calculator is better than this. That watch can't even tell time. How useful is that? As stated above, a number of cell phones have calculators now.

  6. Ive seen plenty of different calculator watches i even think my math teacher in high school had one. I love that guy. Math is my least favorite subject but he was my favorit teacher. This wrist calculator looks crazy i dont think i could figure out how it works. I feel like it would be more time trying to figure out the answer on it then doing the math by hand

  7. That's really a vintage watch. The buttons are always the first thing to die. Here's a thought - I wonder how man 20 somethings or younger where a watch of any kind. Who needs a watch when you have your cell phone. I predict wrist watch sales will experience a slow steady decline for years and that "land" phones will be a thing of the past.

  8. It's convenient if you wear a watch on regular basis. I don't, but I carry my cell phone all the time. So, I also think cell phone calcuators are much more practical for today's times.

  10. I remember getting a calculator watch for Christmas one year in middle school and it definitely didn't look anything like that! It's a marvel at how much we have advanced in every way in society, even through wrist watches.

  11. Wow when I saw this picture I thought it was some kind device to measure something not a calculator watch. I have never seen one of these it looks pretty interesting. It looks complicated to use but at the same time it looks very interesting.

  12. I remember the geeks in middle school had calculator watches and the teachers always collected them when we had math tests. I always thought it was useless because the buttons were so small. I guess it never took because it is too impractical. It seems very James Bond-ish though.
