  • Casio TGW-100 [827] Tri-Graph Stainless Steel

  • Here's another favorite of mine. Even though I have ... (I lost count) many many watches, this watch finds a lot of wrist time. Let me tell you why it is so awesome!

    Oh yeah I still haven't told you what it is.

    It's the Casio TGW-100, Tri-Graph stainless steel watch.



    This watch gives you very different first impressions depending on how you are introduced to it.

    When introduced through pictures, the first thing that pops out from this watch is its "Tri-Graph" dial. A design similar to these can be seen in modern G-Shocks, but these 3 circles actually serve a function!

    The left circle shows the current time in analog format, the middle circle shows if the alarm and/or hourly signal is set, along with AM/PM information. Finally, the right circle shows the seconds. Yes, that right circle actually has 59 individual display segments!

    If you handle the watch in person, the first thing you notice about this watch is its impressive all-stainless steel construction. It is a nice hefty watch made from a block of stainless steel. But it's not a boring shape, either. Casio managed to carve the stainless steel block into a quite fancy shape, as you can see below.





    And of course, it features a stainless steel screw-down back cover.



    Even the buttons are nice and sturdy. They are tiny stainless steel pieces with a tiny stainless steel spring & o-ring. The button is surrounded by a cylinder, as you can see in the pic. Casio drilled 4 holes into the stainless steel case, then inserted 4 small cylinders to house the buttons. I am not sure why Casio designed the buttons this way. Perhaps it increases the water resistance, or perhaps it is somehow cheaper this way. Or maybe they thought it looks cooler this way? Anyway, this is how it's made. Actually many vintage Casios have this button-cylinder configuration.

    Moving on...

    My only gripe is that my particular watch has a lot of scratches on it, and I don't have the original band. But it's extremely comfortable to wear and I love wearing this watch.



    Unlike many other Casio watches, this watch's dial is not painted directly onto the crystal. Instead, the dial is a piece of metal (or is it plastic..?) that floats between the watch crystal and LCD panel. A very nice design!

    Now lets go back to its features.



    I already described the main display screen. Obviously the large digital segment shows the current time, where as the small corner shows the date. If you press the top right button the large segment shows the date & day, while the small corner shows the year.

    The watch has 5 daily alarms, an hourly signal, one dual time, a timer and a stopwatch. The only thing missing, (and it's sorely missing!) is a light. There is no light on this watch, so I cannot enjoy its awesome screen at night. :(



    When you're setting the alarm , the current time is displayed where the date is normally displayed. The left circle will show the alarm time instead of the current time.



    In dual time mode, the analog and main LCD shows the secondary time, while the small corner shows the current time.



    The stopwatch is fun to use, because the rightmost circle goes around-n-around.

    Oh did I skip the timer?



    When the timer or alarm goes off, the watch makes a series of beeps just like any other Casio watch. The thing that's unique about this watch is that the dials go bonkers. Yes, I said it. BONKERS.

    Finally, I want to introduce the watch's family before I end this entry.

    Casio often makes several versions of the same watch. Sometimes, they would make a watch that comes in silver or gold. Or they would make one that comes in blue, green or black. Just as often, they would make a watch that comes in chromed-plated plastic or regular black plastic. Now in all those cases, Casio would use the same basic model number for all those variations. Sometimes they add the letter G to the model number to differentiate the colors, but the basic model number would stay the same.

    But once in a while, Casio would make watches that were identical yet totally different, with different model numbers. This watch is one of them.

    Here is the plastic version of this watch, the TGW-10. The inside module is 100% identical.



    They also made a desktop clock version of this watch too! It's called the TGQ-200. It is 100% identical, except huge. I love this clock just as much as I love this watch. One of these days I might attach a very large strap to it and wear it.



    Hope you enjoyed this entry!

  • » Hey man, this is cool, I was surfing over the net and stumbled upon your blog about this watch, it was and still is my only ever watch i,ve owned I got the one with the plastic case, but anyway.
    I bought the watch I think half way the eighties and payed 139,- gulden back then, probably around 100,- dollar, wich was a lot cause I was on allouwens back then. I love the ''bonkers'' part on it too, did you know if you press the lower left button long enough till it switches back to normal time, then it will do it all the time untill you press something then it will stop.
    And I still have it, the wristbands are long gone so I cary it arround in my pocket.
    Every other watch seems wrong to look at you know. Did you check out till when it will give the good date? mine will will stay ''good'' till the year 2019.
    So I have 10 years ''carrying time'' left.
    Greetings and have fun, Ray.

  • by: JLO, submitted Friday, June 26th, 2009 - 7:07 pm
  • » JLO, actually, that's incorrect. This watch does have an alarm which has a decent volume. If your alarm doesn't work, then something is broken or misaligned inside the case.

  • » I have one of these, I've been wearing it every day since I bought it in 1988. I also got it at Service Merchandise IIRC about $90. I replaced the band with a metal strech band b/c I am allergic to the black plastic stuff. It's pretty scratched up, I've dropped onto the pavement countless time and even run it over with my car once. But it still won't die! It's also only on its second battery.

  • » I bought my Casio TGW-10 from Brendles in 1990 (http://en.wikipedia.org/wiki/Brendle's) and used it up to about 2006. Just today (Aug 25, 2009) I bought a new battery for it and replaced it like I did the one previous time it needed a new battery and this time nothing. It doesn't work. I looked at new Casio watches at the store and none had the 5 alarms, the ease of use, or the cool look of the TGW-10; so I plan to add this watch to my ebay watch list and hope to get a replacement soon (2 sold within the past week).
    P.S.
    I never saw the Tri-Graph Stainless Steel version of this watch and was especially surprised to see the clock version (TGQ-200), I must have the clock. It is so awesome. I like this watch so much I scanned it and planned to make a Flash version of it for the computer, but time is scarce so the TGQ-200 will do nicely.

  • » @ Glenk;
    1. Push lower left button once to go to 'alarms'.
    2. Scroll thru the 5 alarmswith the lower right button till you reach ':00'
    3. Activate this alarm by pushing the top right button.

    Now the signal will sound every hour.

    Richard

  • » @ Robert regarding no sound;
    If you put the back plate upside down when you replaced the battery, the speaker will not work hence no sound.
  • by: Tat, submitted Monday, September 21st, 2009 - 11:27 pm
  • » Regarding -No Sound.Don't forget that sometimes you need to use the "reset" inside the watch. (It involves "shorting" the back of the battery with a small round gold colored contact, my brother had a TGW-10 - as have I, purchased in September 1993 and still going strong - and took it to have a new battery installed for about £15, only to be told the watch had died (he had taken it to a professional jewelers), he then bought an identical watch (after being told it was no longer available, from the same jewelers). I "fixed it for him for 65 pence (the cost of a panasonic battery).

  • » Yea, got my tri-graph when I was 12 years old. Some where around 1988 or so. Its the all platic model and just starting to wear it again. Got a new battery installed and seems to be running perfect. Brings back old memories.

  • » I bought my TGW-100 in September 1992 for 200 Dutch Guilders (about €90.75)and after replacing my rubber strap band a couple of times I decided to put a Velcro one on it. Of course I kept the original metal Casio closure, just in case. After a while the two metal pieces (‘alarm chrono’ and ‘water resist’) on the top and the bottom of the glass came loose, but those I kept as well. Just in case...
    A couple of weeks ago I was in a nostalgic mood and I decided to "restore" my watch to its original state. So last week I bought a nice "close to the original" strap band on Ebay, and last night when I got it in I immediately mounted it on my watch, of course with the original metal Casio closure.
    The two metal text pieces were dented and the black lacquer was worn of on the edges, but after retouching them with some black permanent marker they are now close to their original state again! With some double sided tape (like the way they were originally fixed to the watch) they are now back where they belong and now I'm proud again on my first bought watch!

  • » What a watch! I bought a tri-graph in 1993 when i was 10 and wore it for 10 years when decided to go analog. still have it in a drawer and got an origional replacement casio strap in Aberdeen when it was still my daily wearer. I dont wear it now but i was really found of it. Why didnt casio but a micro light in it though??? It would have been the best spec digital ever then, after al if you want a calculator, use one. Those crazy japs and their 5 alarms.
    At least we all know it deserves cult status friends...
    Love it.

  • » I am so pleasantly surprised to find people who love this watch. I have a black plastic 827 TWG-10 and I am at the verge of tears because I replaced the battery (for the second time ever), but now it does not make a sound. This is my “war watch.” I am about to back to the war zone and it would be the first time that it does not go with me. I love the five alarm feature, but the best part is that the level of the sound is very powerful. Live long and prosper everyone.

    Woah what a great piece. I'm just discovering it and loving it.
    I wish I could find an original strap for it. For now Its gonna go on a Nato.

  • » Wow, I can't believe the love for this watch. I was given my TGW-100 by an ex-girlfriend back in the late 80's and have been wearing it almost every day since. The band has been replaced several times but I have only been through 3 batteries I think. I think I have timed the airtime of every flight I have been on over the last 20 years+ with this watch. I hope it lasts me the rest of my life.

  • » I rememered this site so i thought i'd pay it a visit again. So nice to discover people like this watch. The sound just gave in on mine a couple of weeks ago. Just red a lot of you guys who have posted here have the same problem. I checked all of the above, but to no avail, the sound is gone. But hey, i love this watch and i'll keep useing it till it's dead.

  • » I owned 2 of these and one G-Shock-ified version back in middle and high school. I was rough on watches. I had each alarm set to go off 2 minutes before class was over, as a signal to collect my books and such to make the trek to the next class across our enormous outdoor campus. Eventually, other students and teachers came to depend on it as a signal to wrap things up. One April 1st, I set it to 15 minutes before the bell. Hilarity ensued.

  • » I bought the TGW-100 stainless steel watch back in May 1988, and it's still my daily wear watch. I've used it for diving, snorkeling, and sports all over the world. Even use the timer for knowing when to up the blinds while playing poker. I have dress watches I wear when I need to but they don't compare to this one, at any price. The durability is out of this world! I've only had to replace batteries and straps every few years. That's the reason I ran across this site, I need to get a new battery but couldn't remember the type. Oh well, I'll just open it up.

    Oh, mine also died on me completely after a new battery replacement a few years back. I did the reset with a 3V lithium battery and some small wire leads and zapped it back to life.

    Great watch. I bet Casio didn't realize how long these would survive!!
