NTT DoCoMo, Inc. , one of the largest mobile communication companies in Japan, put the WRISTOMO™, the world's first commercial wristwatch-style Personal Handyphone System (PHS) mobile phone, on sale from May 7, 2003. The WRISTOMO works on the PHS mobile network in Japan.

The wristwatch costs 37,000 yen (excluding tax) and comes with a standard accessory kit including battery charger, cushioned pad and adjustable wrist band. An optional cable (SI1001) that connects the WRISTOMO with a PC to exchange data costs 6,200 yen (excluding tax).

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

The WRISTOMO is compatible with the "PALDIO E-mail" service to send/receive e-mails up to 6,000 alphanumeric characters. No Internet connection contract is required to use the service.

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

The WRISTOMO can automatically exchange data with a PC to synchronize information, such as the address book or journal in Microsoftoutlook®. Whenever information stored in the WRISTOMO or PC is changed, the other device is automatically updated via the mobile Internet or an optional cable.
