Hello,
Looking for help trying to find a side knock mechanical pencil. I lost it 12 years ago and since then I been trying to find a replacement without luck.
Pencil description: it was a metal body, silver color side knock pencil. And at the end of the pencil, it had some kind of word count or watch built in it, (it was broken when I got it and was trying to fix it).
If anyone can give me any leads where to find a similar mechanical pencil. Would be very appreciated
Thank you
Did it have a button on the side or was it a body knock, meaning you bend the body to push out the lead?
Sorry about that, it is a body knock
Yes!!!
These in the photo are called the Pentel Windom. You can sometimes find them on eBay, Mercari (Japan), and Yahoo! Japan auctions.
Thank you very much for all your help!!
You bet! Have a great day!
Note that a few other brands made these. KOKUYO from Japan and rOtring from Germany.
Here’s a rOtring example, up for sale on eBay: https://www.ebay.com/itm/115372374728
Did they also provide them with the digital clock?
I am not sure. I’ve never seen a rOtring with a built-in clock, though.
Neither I. That’s why I suggested the Pentel. @pearsonified may know if anyone else has a body knock with a digital clock.
Those clocks take very tiny LR41 batteries, usually 2 of them… and they last about 1 year. More of a novelty than practicality…
Please don’t get it as mockery, but I think about the mentioned word count feature … With the KT mechanism this should be possible, right? At least for writing in cursive script – I think it would be a fun feature 
That was my in the meantime replacement pencil
The Windom is one of Pentel’s most generic offerings—the same pencil appears in Kokuyo’s and rOtring’s body-knock lineups.
I assume the only reason Pentel greenlit this pencil is because their version was noticeably different from those offered by Kokuyo and rOtring; namely, Pentel’s version included a digital clock.
As far as I know, this is the only body-knock pencil with a clock.
Interestingly, the “pencils with clocks” era now looks like a brief marketing frenzy in hindsight. Pilot produced versions for itself and for Platinum (same basic chassis with Pilot’s best-in-class precision etching), and you really don’t see much of this from the major OEMs in any other category of pencil.
A bit like those massive wrist watches with a calculator keyboard.
I can only curse myself for not having had one!
(well I was too young in 80s, it was something that you’d see in engineering students which were 10-15 years older than I was)
Yeah, there was definitely a short-lived “rage” period where all of these LCD pen-clock models came out. Zebra, PILOT, Platinum, and even Sailor – these big name brands all made pen-clock models. Some even have tiny buttons so you can alternate between time and date, even seconds. Others just show time. There’s usually a flush mounted button for pressing with a tooth pick or pen tip, to put in setting mode.
Or maybe it does come true one day? 
UNI actually has released patent on writing amount counting device, based on kurutoga…
But even though recent UNI purchase announcement mentioned the issue of dealing with future digital inputs, I still don’t believe this could be serious patent. These attempts are more like they’re proving that traditional industry can still have a place in the future era, rather than become future industry itself
