Joining up with Elon Musks Mars expedition? This is the watch for you!<\/p>
This is a little known but true blue space watch that was used by a Japanese Astronaut on one of the shuttle missions. It spent a month in space. It is known as the Space Navigator and has a 6M23 movement which is just full of fun features. It dates to Jan. 1993.
Made of titanium, it has a sapphire crystal of about 1mm and measures 45mm in diameter including the crown. The pushers are screw down or actually screw loose to allow for pressure to bleed from the watch when in space. No crystal popping off as with the Omega Speedmaster ... This is a feaure unique to the space navigator and not seen on other 6M23s.
Another feature of this calibre is that in the chronograph mode the number of elapsed days is indicated by the date window! Yes, the space navigator uses the chronograph to count elapsed days together with the "Intelligent Calendar", which was an industry first when introduced in 1991. It is controlled by a stepper motor, and this enables the date ring to be used for chronograph operations as an additional counter.
For elapsed times under 24 hours, the date window reads the current calendar date. The 24 hour dial indicates hours, the minute hand minutes, and the seconds hand seconds. When you go over 24 hours, the date window will change from the current date to "1", and the 24 hour, minute, and seconds hands simply start over. After two days of timing, it will go to "2", etc. If you go from chronograph timing to normal time mode without resetting the chrono, you can watch the datewheel turn all the way from the number of elapsed days to the current date. Go back to chrono mode, and it goes back again to the elapsed days.
The orbital rule bezel is there to indicate the altitude and velocity of a space craft orbiting the earth at an altitude of 1400 miles or less. If you happen to be watching a shuttle taking off on TV, you can use the watch to time its orbit then use the bezel to determine how high it is and how fast its going.
The Calendar can automatically adjust for leap years up to 2099. The second hand indicates how many years have passed since the last leap year. The hour hand points to the month on the inner bezel. The date window has a very light magnification cyclops built into the crystal. The alarm and dual time features are there too...
