Casio throwback calculator watches - gentzel - 11-16-2024 08:19 PM
Man, this brings back memories!
Casio's new calculator watches will take you back to 6th grade math class

They look pretty nice. I was just thinking I might want to start wearing a watch again. Not a smart one. But this one isn't exactly dumb! I'm curious what architecture they will be using and whether it will have 17digits+ of precision of their latest range of calculators.

Bring back the DBC-150, damn it!

In the mid 1980's I owned a Casio CA-50x (all metal) calculator watch with metric conversions. I bought it cheap at a market in Genoa, Italy. However it died and is long gone. These days they're considered "rare" and sell for a lot on eBay.
Some years ago I purchased one of these out of nostalgia.

In the early 1980s, one friend of mine had one of those Casio watches that played tunes.
(Such as on a birthday, it would play "Happy Birthday" on the hour.)
A mutual friend got tired of listening to it, and cooked it in a microwave oven!
He then replaced our friend's watch with a Casio Calculator watch.

The Casio calculator watches I've seen a basic 4-bangers. No memory or sqrt(). 8-digit. No scientific notation.
Only useful (IMO) if you're out shopping/traveling etc. and you want to perform basic arithmetic.
With the exception of metric conversions the one I have now has the same functionality as the stainless steel one I had in 1985.

PS: I rarely wear a watch these days.
PPS: I had to look up the exact model number of my 1985 one. A rare (to find working) CM-321 as pictured below.

Although I have hundreds of watches (my compulsive collecting vice is not limited to caculators) I almost never wear one. Only when I go hiking with my wife because she always wants to know how many kilometers we did. For that I use a smartwatch with built-in GPS receiver that I bought new from eBay for 20 Euros. When I don't wear it, a charge lasts over four weeks (eat this Apple watch!) so it is almost always ready to wear.
And regarding calculator watches: There can be only one! (or rather zero-one) :-)

Can be only one? Would that be the Hewlett Packard Model One Digital Wrist Instrument, a.k.a. the HP-01? Or possibly the Casio scientific calculator watches (CFX-200 and such)? I've had both and worn both considerably. Amazing for their times!
