The Casio Pentagraph (1989)

This is my Casio DW-7200 Penta Graph Referee match timer which was manufactured in Japan in 1989 and a rather rare find today especially when it’s in almost perfect as new condition.  This model is from the DW 7000 stainless steel series and in regards Casio digital model, is just a little different from the ubiquitous resin cased ones at the time.

With its 200m Water resistance and heavy solid stainless steel case, contrasting gold bezel, plus gold plated pushers and large clear crystal, it is a very sharp and stylish watch.

This DW-7200 was supplied originally with a black rubber (resin) strap (the DW7200G was the bracelet version), but this one’s strap disappeared along the years and although I bought it with a solid stainless steel bracelet with a Casio buckle fitted which the seller had sourced and which complimented it very well, I decided I liked the black contrast and it seemed right to see how it looked, so I fitted this black silicon deployment band as an alternative, which I

show here.

I particularly like this model with the inset gold bezel effect in contrast to the stainless case, and style-wise even after nearly 30 years it looks as if it was made yesterday.

So what does it do?

As to functions – this clearly displays Time, Day and Date, Month, am/pm and features 5 independent Alarms plus an hour on/off signal.  A Chronograph and a Score Keeper for 2 sides – you can keep score while the timer is running in another mode.

It also features an amazing array of Competition Timers:  1 free timer, 1 auto timer and 9 other sports timers (Boxing counts 3 min-break-3 min, Soccer 45 min–15 min break -45 min and so on AND these can all be changed to suit changed rules and/or timings in the future or for different sports.  In other words this model is ideal for any number of timing tasks (find one that does that today!).

Named Penta Graph basically as it features 5 digital counter/graphs, including a selector display and of course the main Time and Calendar display @6.  It’s powered by a standard Lithium CR2016 battery.

With many of these vintage digitals, it can take some trial and error to see what’s what, but fortunately it’s not difficult to master, which is a plus point regarding these vintage modules – their ease of use and general intuitiveness.  However in this instance I do have the instructions Casio928PentaGraph which also covers 7 other modules.

Note this model sports a 200 m Water Resistance, courtesy of the circular solid stainless steel screwed back.  The Module and model number as usual are scribed on the back (I have obscured the serial number – an annoying consequence of the ease of Internet abuse).

This is a great addition to my little collection and it has a rarity simply owing to it’s terrific condition and unusual functionality, which I love and the fact that such complications have been integrated so seamlessly into such a stylish watch.  A bonus is that’s it’s also easy to use and yet accomplishes so much.

It’s odd when you talk of rarity and the likes of Casio, Citizen and Seiko in the same breath as these companies were and still are mass producers of watch models.  It’s not as if they produced Limited Editions in those days, but often the rarity is simply that these models are no longer around.  Unfortunately battery technology lagged well behind the module science and many watches stopped working owing to battery corrosion.
In many cases the owners simply chucked them in the drawer and probably bought the latest one as a replacement, with the old model eventually being chucked out at some future date.

So to find any 1970-1990 digital watch model in pristine condition is pretty much a rarity in itself, let alone being rare for any specific functionality.  This particular DW-7200 however scores on all fronts – great cosmetically, fully functioning module wise and unusual in it’s actual feature set.  And let’s face it where else can you get a “referee” match timer model today as stylish as this?

Note – I seem to recall a PGW-30 and 92, with similar functions but both were resin cased I think.  Also a Casio SW-110(512) Soccer Timer, but none quite as stylish as this model.

  1. Hi, yes the Casio Pentagraph is indeed rare. Believe it or not I have one too, in “As new” perfect condition. Mine still has the original strap, but its not rubber. Mine has a tan brown leather strap which I feel is a better compliment to this watch. I also have the paper instruction booklet that came with it.It cost £65 when it first came out nearly 30 years ago. No idea what its worth now. I don’t wear it any longer as it has no back-light and my eye sight cant make out the dials but my girlfriend at the time bought it me for my birthday. It must have worked as she is now my wife.

    • Hi and thanks for your comment. Nice to hear of another Pentagraph even without the backlight (maybe just a battery needed)and interesting to note that you say the leather strap is original. This seems unusual, whilst models did appear with resin, rubber, composite resin/steel and steel bracelet – I have never seen one with an original leather strap. The reason I say this is the watch was advertised with the 200M Water Resistance as a named feature and leather or even webbing would not have been the best choice unless oiled and water proofed, but who knows?
      Anyway I still wear mine often and I love the fact it draws comment every time. So yet another well designed and good looking Casio model from those days that still looks good today.

  2. Hi, I have just recently set about restoring my DW-7200 and when I replaced the battery I found that the beeps and alarm sounds do not work now. Do you know off hand if this model had an alarm spring?

    • I remember it had a standard Lithium CR2016 battery and there was a frame spring which contacted the screw back. Other than that I can’t recall anything else.
      I can’t recall anything that would prevent the alarm beeps from working – (apart from making sure the new battery is actually OK and not a bad one!).
