Seiko Astron - SBXC103

When it comes to tool watches the Seiko Astron is unparalleled in its functionality. Containing a laundry list of 'can do's' it's easier to mention what it won't do than to list what it does. It can't do your taxes, it can't clean your apartment, and it can't save the Marvel Cinematic Universe!

But it will give you world time functions in upto 39 time zones. It will constantly monitor GPS signals to give you the most accurate time measurement possible. It will constantly adjust the time so you don't have to. And there's a perpetual calender until the 28th of Feb of 2100 .. so, if you still need that in about 75 years time .. well done you :P

Sporting a dual curved sapphire crystal, titanium case and lumibrite on the hands set this technical marvel will be sure to keep you informed of the time .. no matter what.

Full kit, box and papers. This watch was originally from Japan and so the warranty would not have been valid in Canada, but as we're authorized service agents for Seiko you're in good hands with us. So buy with confidence.
