Here's a E-Paper watch that interacts with your android phone: http://www.kickstarter.com/projects/...droid?ref=live

Edward beat me to the punch. I was going to mention the Pebble which looks a LOT better than the one in the OP. Granted, I don't think those Phosphor watches look terrible... But, I would take the Pebble over it any day of the week.

Agreed, the watches in the OP are ugly.

A "screensaver" clock on the Kindle wouldn't work, because the screen never gets updated when the Kindle is asleep. It would simply show you the time that the Kindle went to sleep, which doesn't sound terribly useful to me .

There is an kindle clock "screensaver" in the Dev Corner. The kindle periodically wakes up to update the clock image (not too often, to save battery). You can set it for 1 minute or 5 minute eink updates, I think...

P.S. It is usually not safe to say the something is impossible (or "wouldn't work"), because somebody will eventually (or already has) proven you wrong. It is much safer to say that you do not know how to do it. Speaking in "absolutes" is always risky. If you leave a sleeping 3G kindle sitting near amplified computer speakers, you may have noticed that it sometimes wakes up and "phones home", when you hear a burst of "cellphone noise" through the speakers, which proves that a kindle can be programmed to periodically wake up.

There is a distinct difference between e-ink and e-paper. The Pebble watch is e-paper which is essentially a special type of backlit display that is viewable in direct sunlight. I'm looking foward to receiving mine in September.

You have to hack your Kindle to do this though, right?

Native mode programs such as the clock do not need to hack very deeply into the kindle. Just a background task that updates the eink framebuffer at periodic intervals. It helps to know that background tasks can be scheduled to wake up periodically even when the kindle is "asleep". Because updating the eink display consumes a significant amount of battery energy, they should not do it too often.

I have a Motorola F3 eink phone. It is phone only, it can't do any fancy thing.

If color eink could ever get deep saturation, I would love an eink display for my Vespa GPS.

[geekmaster]

The current color EINK technology is just the black and white eink we are familiar with, with a color filter overlay on the screen to tint the white particles under it. Because this blocks a significant amount of light (absorbed by the color filters), it will never have saturation anywhere near what you get from light-emitting displays (LCD, CRT, OLED, or plasma).

However, there are different eink-like passive color display technologies that may have better color saturation, but the ones so far available appear to have a very narrow viewing range that shows this color saturation (off axis viewing has very low saturation).

Technology has some catching up to do to bring us the eink color technology with the display quality we crave, but it WILL happen (right after we invest a significant amount in a lesser-quality passive-color device).

Its other major issue is that it halves the linear resolution of the display, because each colour "pixel" on the screen is actually a 2x2 block of four pixels on the actual device, so a screen with a "native" resolution of 200dpi becomes only 100dpi with the colour filter.

All these e-ink watches seem like they're reinventing the wheel. A $10 Casio tells time perfectly, lasts 3-4 years on a single battery and is viewable day and night.
