Seiko has announced an ultra-slim watch featuring an electrophoretic display (EPD) that will be available in March 2006.

Called the Spectrum, the limited edition (only 500 are being made) watch features a microcapsule-type Electrophoresis display module, offering a thin flexible design that could bend around your wrist.

Seiko is promoting the benefits of the watch as having a high contrast display of pure black and pure white particles, which allow the same contrast as on a printed page and twice the contrast of a LCD panel.

The company is also boasting a thin design, low power consumption because you don't need a backlight and no restrictions in size.

The watch is the result of a joint development effort, combining ‘Electronic Ink' technology developed by E Ink Corporation in the USA and Seiko Epson's advanced display manufacturing and electronic circuitry techniques.

The watch will cost around £1000 when it is released next year.
