I had one of these around 1988. I was working in a machine shop, and the calculator functions came in pretty handy. Unfortuately, the case cracked from shock while working, but it took a couple of weeks for it to stop working, even though it was constantly being soaked in cutting lubricant. I lost the job not too long afterwards, and I graduated to less dorky watches.
Best watch ever. Twenty four years after I got it as a gift, I’m wearing it on my wrist as I type this. The back plate gasket has disintegrated and I’ve chipped a corner of the front glass. But it continues to function as well as ever. In addition to scientific functions like roots, sin, cos, tan, log, pi, deg/rad/grad, parenthesis functions, etc. it also does very handy englishmetric conversions. And, of course, it has a stopwatch and alarm. It does standard or military time and has a light button for night viewing. To this day, no other device (watch or otherwise) has matched its performance and compact form factor. Though I too have less dorky, even stylish and refined watches, this one remains my favorite and I’ll mourn the day it dies.
Bought mine in 1981. Have worn it everyday since. The light is starting to go and the buttons are starting to stick a little but still work. I plan to keep wearing it for another 27 years (I will be 70 then). Other than replacing the battery every 12-18 months, it is a great watch.
I have a CFX-200 I bought while stationed in Korea in the early 80’s. I’ve lost the manual for it and haven’t worn it for years. I finally put a new battery in it but I’ll be darned if I can remember how to set it. If someone could e-mail me those of even a scanned copy I would be very appreciative. I would like to be able to use it again.
I had bought one CFX 20 in 1983. Its a marvell of functionality in tiny space.
It was very handy for navigation calculations while at sea. And functioned for over 8 years, before succumbing to humidity.
I still have the entire watch intact, no damage at all except for a little whitening of the buttons.
Would love to see it working again.
I had one of these. Why don’t they re-make them. Please! One of the buttons fell out and I sent it to Casio to see if it could be repaired and that was the last I saw of it :-(
Had everything you needed at your fingertips. I want one again
I had one of these in the mid 80’s. Bought at Best Co. near Washington DC, and once got caught using on a test in school I have been looking at these on ebay and considering paying a rediculous amount. I find myself being very nostalgic these days, I fear it is unhealthy and may need to see if they have a pill for this!
Hey lee - I’ve finally decided to sell my near-perfect CFX-20. It was seldom worn - I preferred keeping it in my pocket without the strap. Therefore, the strap almost unused! Has been in my drawer for near 25 years. Replaced the battery last year and it functions perfect.
I’ll eventually put it on Ebay, but it is available now. Can email my google account: 2poker2
I have this watch I bought in Bahrain in 1983. It is still working and I only need to replace the battery every 18 months
or two years . All keys are functioning and doesnt have any physical damage. I can sell it on good offer. Thanks
[…] I’m not sure if the 1983 Casio CFX-200 is the best balance of function and I-could-actually-wear-this-thing, but it’s the most wonderful usability trainwreck I can find. 23 buttons! Many of which are multifunction buttons. Surely this is the Audi R8 of calculator watches, in which misuse will almost certainly lead to death. Got a better one? I would loooooove to know about it. For now, you can check this baby out on eBay. Auction’s going on now. [eBay via Oobject] […]
Hey I know this is off topic but I was wondering if you knew of any widgets I could add to my blog that automatically
tweet my newest twitter updates. I’ve been looking for a plug-in like this for quite some time and was hoping maybe you would have some experience with something like this. Please let me know if you run into anything. I truly enjoy reading your blog and I look forward to your new updates.
