NTT DoCoMo to Market “WRISTOMO,” Wristwatch-style PHS Mobile Phone


NTT DoCoMo, Inc. announced today that it will soon begin marketing the WRISTOMO™, the world’s first commercial wristwatch-style Personal Handyphone System (PHS) mobile phone.

Marketing will be handled exclusively through the Internet at, which will be opened today at 3 PM (Japan Standard Time). Customers can begin placing orders on the product launch day (to be announced).

An actual waterproof wristwatch, the phone opens up into a functional PHS handset when buttons on either side of the watch face are pressed.

The WRISTOMO is compatible with the “PALDIO E-mail” service, which enables users to connect send/receive e-mails up to 6,000 alphanumeric characters via the Internet without having to sign up for a provider.

The wrist phone transfers data at up to 64 kbps. The WRISTOMO can access the “Browserphone Content” web pages of DoCoMo’s mopera service, as well as sites based on a subset of HTML, designed for mobile internet services such as i-mode (compatibility will depend on the site). The WRISTOMO is also equipped for DoCoMo’s “Location based Web Sites,” which provide information about restaurants, weather, transportation and other content based on the user’s current location.

The WRISTOMO comes with an information synchronization feature that automatically exchanges information with PCs, such the address book or journal in Microsoft Outlook. Whenever information stored in the WRISTOMO or PC is changed, the other device is automatically updated either via the mobile Internet or an optional cable.
