It's not a G-Shock, but wow does it look handsomely designed. I remembered seeing this model for the first time in 1985, when I ended up buying my DW-2000. The titanium case TW-7000 was way out of my price range, costing over $100. In retrospect, I should have bought it then... in addition to the DW-2000, and watch budget be damned. I could skip a couple of nights out to fund it. But alas, I didn't. And then I forgot about it for quite some time. Later, when I revived my interest in G-Shock watches, I took notice of this watch again. Unfortunately, their resale value has scaled up relative to other vintage CASIO watches, though not as bad as the Wide Temp and other very obscure low production models.

Bidding often goes quite a bit over $100 when these pop-up on that auction site, the most recent I spied finishing at $180 to some buyer in Spain (who'd be facing a hefty shipping charge too). I nabbed this rather used example for a very cheap price, because it wasn't working and has plenty of small scratches from use. The reason why it was non-functional was because some careless person misplaced the battery clip and substituted one that didn't work right. The seller had bought this in an estate sale and could get the watch to activate only temporarily. Although 548 modules aren't easy to find, they were installed in a number of older CASIO models and can occasionally be found for sale in beat up watch cases. Since the casing of this TW-7000 didn't look too bad, I figured if I won it that later on I'd eventually be able to get a donor 548 module sometime down the road.

Well, as luck would have it, the module was fine and I was able to modify the supplied incorrect clip, coaxing it to work as a surrogate with success. The watch came to life and works well! I even time adjusted it and it's looking like it'll be +2 sec/mo accurate. I'll eventually have to do a review of this watch and go into more detail about it and the 548 module. In the meanwhile, here are some photos to give you some idea about what the watch looks like. Note that the case has "TITANIUM" prominently imprinted upon it (as titanium watches weren't common then, so companies had to boast about it), while the band is actually stainless steel (yet fairly light weight and comfortable--I got lucky that it was sized perfectly for my wrist). It's also a screw back case, and the backing has "titanium" imprinted upon it as well.

I don't know why, but a screw back always looks like a proper watch, whilst the 4 x screw ones just don't - odd?? :think:

Yeah, a screw back always looks better to me, much more clean and solid. The 4 screws appear more like an obvious cost cutting measure. However, for models that go a very long while without battery replacement (like tough solar), it's not so bad as long as the case back is refined, with interesting imprints and chiseled edges giving it a more presentable look than the generic brushed steel back plate.

Cool and obscure piece -- nice find. Is that corrosion we see on the bracelet, or gunk that needs to be cleaned? Either way, this is a watch that would also look good on a resin strap....
It's gunk left behind after my superficial cleaning. I should give it a more thorough scrubbing with a toothbrush. I think they did have one version with a resin strap. I'll have to measure the lugs and see about a suitable replacement, to change up the look of the watch from time to time. :)

I wish Casio would come up with something like that again - full metal case, screwback, all digital, standard lugs - I'd be all over it in a heartbeat. Congrats on that beautiful piece! I remember someone posting a vintage Casio catalogue here once including this model - if I remember correctly it even has multiple alarms, right?
Agreed, and thanks! I'd pay a good $100 more than typical limited edition G-Shocks for a similarly designed solid looking titanium G-Shock with partial resin bezel to protect the edges and screw back case. If I had the appropriate software, I'd love to give a go at making a design based on the TW-7000. Alas, the module has only one alarm. The 242 module of that era is the one with 5 alarms. But what's great about this one is that the beep tone is LOUD, very close to a G-3010. Also, the hourly chime is half hourly as well (single beep @ 30 past), and makes a quad beep at 12AM/PM. Another thing... I don't know if it's the 548 module itself or just my particular example, but the LCD segments are extremely black with sharp edges. It's the best looking LCD up close of all my G-Shock watches. Watching the segments change under magnification is really cool. :-!

Congratulations Gary, with a good find, nice work and a great looking watch :)

I imagine, it'd look cool on a James Bond Nato strap like this: http://i.ebayimg.com/t/RAF-Military...-G10-Nylon-Keeper-/00/s/MjYyWDI2Mg==/$(KGrHqJ,!qUE88fkHsuFBPU8ooGbh!~~60_39.JPG

One thing I really like about this model, is how un-cluttered the face are, it got a much cleaner look, than most other Casios :)

PLEASE Casio, make a new edition of this one - same clean case w. screwback and high contrast display and loud alarm. And only add 5 alarms, one snooze, EL and not much more.

That's an awesome looking Casio.

I think this has been said many times, but Casio doesn't make watches like they used to anymore
No, they certainly don't. While they have made some outstanding modules, and introduced a few great casing designs, so much of their focus seems to be on rehashing the easily made stuff. I do appreciate refining a successful style. It's no accident that the Porsche 911 still lives on today, that same base design element from the early 1960's carried forward to the present 997 series, gradually refined along the way. Similarly, though not as extensively, the venerable DW-5000C has undergone a number of revisions with the same basic casing design intact. Functionally there have been numerous improvements, but... we seem to find the 5000/5600 series pretty much capped with solar and atomic as the last improvements. Maybe they'll manage to introduce a compass at some point, or perhaps a bright LED for alerts and momentary illumination, but certainly there can't be much else introduced...

I wouldn't mind seeing the TW-7000 re-introduced, slightly thicker with a G-Shock dampened module. No EL-backlight, but instead an LED with mirrored end piece to reflect the light and fully illuminate the face, reminiscent of the old style bulb. No solar. No atomic. Just a really nice clean face and a double-calibrated movement so that it's within +/- 2 sec/mo.

You're welcome. Yeah, it's more like what I'd want the 5600 to look like. With less label clutter you can pick up on some subtle but nice design cues, like the slightly raised trim around the LCD opening, with a slight "picture frame" indentation around the inside. I really hope to find a near mint example sometime in the future, but I expect I'd have to pay dearly for it. Yesterday, a DW-3000 (all titanium 300M watch with same module) was up for sale on that auction site, closing just under $300. A hefty price given how it was a B+ grade example, especially since the location meant a $25 shipping charge to people in the USA and Europe.

A Casio digital watch made of titanium? I'm in. Amazing find Gary. I love it that you've get your hands on this classic and brought it back to life. A modern version with a titanium case and bracelet is quite welcomed.

Edward, I'll make a guess and assume that you talked to some jeweler who scratched your watch and told you this false information. It couldn't be farther from the truth. Screwbacks can be removed by anyone with the proper tool and know-how. And, a very decent tool costs as low as $10 (cheaper ones can be had, but they aren't precise and wear out prematurely). So, in essence, there's no problem with a screw caseback watch except for lack of knowledge on how to open it.

One easy way to prevent a scratch is to simply use a sticky rubber mat (it'll tighten plenty enough for most purposes). The other is to put painter's masking tape over the holes, in case of unforeseen slippage with a tool.

Totally agree! Mine was more expensive - ÂŁ5(!), but I've never scratched a back either...

Good advice - if I'm doing a friend's watch, I'll use tape. Mine, I'm fairly confident to go ahead without...

I still wear this watch frequently. It's so great in many respects, with my only complaint being the dim lighting (tiny bulb is just barely enough to read the time). I truly wish CASIO would re-issue a limited edition version of it. Meanwhile, one day I'll have to track down someone who can modify an old 548 module, swapping out the bulb with a micro LED! ;-)



The white face version provides a nice contrast, but I find the gray version slightly more appealing.

^ He got it on that "other" auction site, in Japan. ;-)

They still pop up from time to time, but usually in pretty well used condition. He got a pretty good buy, I think. The sound wasn't working after a battery change, but it turned out to be a bent prong. And the bracelet was just a tad short, so he got a bracelet extender that worked very well.

Do you ever regret letting go of yours?
