Based on the Thiem-Work Scope Clock Kit
Until now, David Forbe's Scope Clock Kit version 2 was the nicest scope clock I've ever encountered. This one, however, is my new favorite. IT is based off of the Thiem-Work scope clock kit (99,00 €). In terms of aesthetics, the exposed tube is a striking change from all other scope clocks that I've seen to date. The inner workings are presumably hidden under the aluminum housing underneath the tube. It is hard to get a scale since there aren't any other images avalable, but the CRT face is 13cm across.
There are some significant differences between this and the Forbe's Scope Clock. This unit appears to have a raster image display rendered using a vector CRT. If you look at the photos below, the images look a little pixelated which implies that the underlying hardware is generating a bitmapped version of the image and then rendering it on this display. In contrast, the Frobe's Scope Clock renders everything as vecor images giving the numbers on the face a much smoother appearance. The trade off is that the Forbes version is much more difficult to engineer but the image looks much crisper.
The other major difference is that the Forbe's Scope Clock uses a GPS for setting the time. The kit that this was based off of uses an internal oscillator. While it greatly reduces the cost and the complexity, it seems a shame not to include it on a clock of this caliber.
If Eric C ever decides to sell these commercially, I will be first in line to buy one!

This appears to be the same clock:

I don't have a lot of information about this clock
This has got to be the smallest CRT clock that I’ve ever seen. The inventor is a little shy on details but the presentation of this clock is simply astounding. Apparently the inventor digitized his own handwriting to use as the source for the typeface. Sadly, there aren't any schematics available or much else in terms of details. While the David Forbe's Scope Clock wins in features, this guy in size and style.
Chris - if you ever want to part with this clock, please contact me!
$999 / on sale soon-ish.
The second version of the Scope Clock is currently in production and will hopefully be on sale soon. The display of the clock is a CRT display originally intended for oscilloscopes. All of the display characters are drawn as vector images, unllike the AVR based Scop Clock kit sold by SparkFun Electronics.
In the updated version of the Scope Clock, the housing has been completely redesign to fit in a much smaller cylindrical housing. I can’t tell for sure but it appears to still be based on the 3RP1A CRT. The time is set via GPS. You need to program the UTC Offset and DST parameters but once it finds a GPS signal, this will be the most accurate clock in your house!
