Itâ€™s safe to say that the Seiko Astron watch line is one of the coolest watches on the planet.
Recently featured in our 8 Spaced Themed Watches That Are Out Of This World, the Seiko Astron is accurate to one second every 100,000 years. How? Thanks to the atomic clocks in every satellite around the world.
The worldâ€™s first GPS watch, this piece remains accurate even while on the move across borders and itâ€™s calendar will not need to be manually adjusted until February 28, 2100. Itâ€™s safe to say that youâ€™re more likely to breakdown before this watch ever does.
