Seiko pays tribute to space travel with special edition exclusive to the US


Seiko has introduced a new Prospex LX U.S. Special Edition timepiece, inspired by the moon.

In tribute to space travel too, it is designed to connect its proprietary technology to its rich history, featuring Seiko’s in-house Spring Drive movement.

In development for over 28 years, Seiko’s proprietary Spring Drive movement continues to function when confronted with harsh conditions on earth, in the sea, or in outer space and can achieve an accuracy of +/- 1 second per day (+/- 15 seconds per month).


This is due to the Tri-Synchro Regulator which uses a combination of mechanical energy to drive it, electrical energy to power the integrated circuit and quartz crystal, and electromagnetic energy to regulate the speed of the glide wheel to minimize friction, ensuring the timepiece’s accuracy and longevity.

The glide wheel spins in only one direction, and this combined with the precise braking system and regulation of the Spring Drive mechanism helps achieve the smooth, true sweep second hand.

Spring Drive has passed the rigorous testing required for space travel and maintained its accuracy and functionality while on board the International Space Station.

Building on the success of its LX line, Seiko has this week launched the Prospex LX U.S. Special Edition.

It features an intricate gray patterned dial representative of the silvered lunar surface and a multi-tone gray sapphire GMT bezel reflective of the light and shadows cast on the moon by other bodies.

A blue GMT hand echoes the view of the earth from the moon, while tracking the time in a second time zone.

Exclusively available in the U.S. market, the case and bracelet are crafted from lightweight and durable titanium with a super-hard coating for superior scratch- resistance.

The case is finished with beautiful Zaratsu polishing to perfectly reflect light and is structured with a lower center of gravity ensuring that the timepiece is comfortable to wear.

The LX U.S. Special Edition SNR051 will be available in January 2022, at select Seiko Luxe retailers, with a suggested retail price of $5,500.
