Astron:

The watch that always tells the right time. Worldwide. With the push of a button and using only light-generated energy, a Seiko Astron GPS Solar watch can connect to four or more satellites, identify the time zone, and set the hands to the correct local time. With a maximum deviation of 1 second per 100,000 years.

Perpetual Calendar:

Perpetual calendar that takes into account leap days and the length of the months, until the year 2100.

Titanium:

Titanium is a metal that is completely hypoallergenic. It's light to wear and strong.

Caliber 5X83:

The SEIKO 5X83 caliber is a prestigious analog GPS Solar Dual-Time Chronograph. This watch can easily set itself to the correct time zone anywhere in the world with the push of a button, displaying the correct local time. The GPS signal indicator on the dial indicates whether the watch is connected to the global GPS network. It also shows how many satellites it is connected to. Determining the correct time zone requires a connection to at least four satellites. When fully charged, the watch connects to one satellite up to twice a day to correct the time. This makes the 5X83 GPS Solar watch extremely accurate, with a deviation of only 1 second per 100,000 years. If necessary, the local time can also be changed manually. The smart Perpetual Calendar function ensures that the watch always displays the correct date until the year 2100. The watch features a Dual-Time function, in-flight mode, automatic DST adjustment, and a chronograph function. The stopwatch can measure up to 12 hours in 1/20-second increments. It also includes an intermediate time function. A second time is displayed on the subdial on the watch face, along with a separate AM/PM indicator. The watch's built-in micro-GPS receiver consumes so little energy that all functions operate optimally on solar energy generated by the solar dial.
