What time is it on Jupiter? Ask Seiko
To Seiko, going into space is no big deal. In fact, any old tat-timepiece will do. If, however, you are planning on venturing outside the speeding spacecraft, then you had better take one of these along with you. The Seiko Spring Drive (US$28,000) is built to work in the vacuum of space, and has been tested on actual spacewalks. Besides letting you know when it’s tea time at five miles high, this watch also gives you date and chronograph functions.
