Seiko Spring Drive Spacewalk Limited Edition SPS005

Seiko Spring Drive Spacewalk Limited Edition SPS005 Arizona Fine Time is extremely proud to announce the epic return of the incredibly rare, unbelievably unique, and one of the most collectible timepieces in Seiko’s history, the Seiko Spring Drive Spacewalk Limited Edition!  After nearly 2 years of waiting, asking and hoping, Seiko USA was finally able to track down, and bring back the monumental Spacewalk back to AZ Fine Time.  This is one of our all time favorite pieces and allow me explain why…

Seiko Spring Drive Spacewalk Limited Edition SPS005

The Seiko Spring Drive Spacewalk was the 1st watch in the world to be custom made from scratch, specifically for space travel.  There, of course, are many watches made and modified for space travel, but this is where the Spacewalk differs.  Starting in 2002, Seiko started researching how to make a mechanical timepiece work flawlessly in space.  The emphasis was solely on functionality, and testing of prototypes began at NASA with microgravity and vibration tests.  All of which were successful.  The next step followed at the Aerospace Lab at USC, where they tested the prototypes in radiation, lack of atmosphere, rapid changes in temperature, and in vacuum chambers.  After all of this testing, all the prototypes stayed in perfect sync, showed no signs of deviation, and the test was considered to be a huge success.

Seiko Spring Drive Spacewalk Limited Edition SPS005 A man named Richard Garriott was a big part of the Seiko Spacewalks existence.  Richard’s father, Owen Garriott, was an astronaut (who actually brought Seiko watches with him to space) which lead Richard on his pursuit to become an astronaut himself.  Not only that, but he lived in a neighborhood surrounded by NASA employees.  Naturally, Richard wanted to follow in his fathers foot steps, but due to issues with his vision, was not qualified to become an astronaut.  While attending college, Richard designed video games, as what seemed to be a hobby, but ended up making a fortune in the process.  With the success of his games, Richard was able to pay off college and even start his earliest investments, one of which was Spacehab.  Through the rest of his life, Richard was an adventurer, going canoeing in the Amazon, meteor hunting in the Arctic, reaching the bottom of the Atlantic to see the Titanic and even gorilla tracking in Rwanda.  This, however, did not satisfy his dreams of going to space.

Seiko Spring Drive Spacewalk Limited Edition SPS005 Once Garriott went to Russia for his near year long training, the production Spacewalk watch went with him.  Accompanying him through all his tests including rotating chairs, tilt tables, hyperbaric chambers, vacuums, and centrifuge training  (simulating 9g re-entery), the Spacewalk proved its perfection.  The entire design was made to withstand all the extreme rigors of space, be perfectly functional and keep perfect time.  You will see the Spaewalks bullhead design putting the extra large crown and pushers at the top of the case.  This allows for ease of use while wearing the gloves of your space suit, and still be comfortable on your wrist while wearing without.

The 48.7mm wide, proprietary, High-Intensity Titanium case is very strong, but 40% lighter than steel weighing only 92.5g.  In order to develop this case, Seiko had to 1st create a new CNC machine in order to manufacture it, and they did so completely in-house.  This allowed for the hollowed out case design that eliminated weight, but also allowed for a large legible dial.  The case is completely air-tight, which is essential because of the vacuum of free space.  In order to achieve this air tightness in extreme temperatures ranging from -4°F to +158°F, Seiko had to develop a new rubberized material for its gasket.

The dial arrangement was very well thought out for easy legibility.  Your continuous running seconds are located at 6:00, with chronograph counter minute and hour sub dials on the upper half of the dial.  The power reserve indicator is located right next to the date at 3:00, using a fuel like indicator reading from full to empty.  The colors for the dial and bezel were to simulate the view of Earth from space, using the bronze colored bezel to symbolize the land, blue accents to symbolize water, and the white to symbolize the clouds.

The strap attachment for the Spacewalk is a Ballistic nylon strap with titanium buckle and velcro fastening.  The piece comes with 2 straps, one for normal wear, and one for outside of a spacesuit that can adapt to normal wrist size.  The use of this material is for its strength and also for ease of use.  The strap used by Garriott (the one for the spacesuit) worked perfectly, and was very easy to take off, put on, and adjust.

Seiko Spring Drive Spacewalk Limited Edition SPS005 Seiko’s Lumibrite material was used for the darkness of space, giving greater legibility in the dark than ever before.  This natural lume applied to the specifically designed hands and indexes are applied in additional layers, which makes it about 3 times brighter than normal.  There is even a luminescent ring around the second hand sub dial allowing you to see its position in complete dark.

In Oct. of 2008, Garriott finally went on his private space mission.  For the movement on his custom watch, the 5R86 Spring Drive movement was utilized.  Quartz was not considered safe, and mechanical is not as reliable, so ultimately, the hybrid known as Spring Drive was chosen for its supreme accuracy, durability, and consistency on Garriott’s mission.  The features include chronograph, GMT hand, 72 hour power reserve indicator and date.  With 416 components, 50 jewels, and and an unbelievable accuracy rating of +/- 15 seconds a month, it is an impressive movement.  Even more impressive, is that the Spacewalk not only functioned perfectly on the 4.5g entry, kept full 72 hour power reserve with the lack of gravity, functioned perfectly (both in time keeping and chronograph function) for 5 hours and 38 minutes outside of the spacecraft  while on the wrist of a Russian cosmonaut, and also withstood the potential 17,500mph re-entry.

As you can see, the Seiko Spring Drive Spacewalk SPS005 required an abundance of research and development from the ground up, which is one of the things that makes it so unique.  The Spacewalk was awarded Sports Watch of the Year at the Grand Prix d’Horlogerie de Genève  in 2010 and one of the pieces that actually went to space, No. 6 of 6 actually in space, sold at Antiquorum auction for $45,600 with proceeds from the lot going to the two charities Richard Garriott supports, the Nature Conservancy and the Challenger Center.

The Seiko Spring Drive Spacewalk commemorative edition is limited to only 100 pieces (thought to have been completely sold out) and retails for $28,000, making it still the most expensive Seiko product to ever hit the US market.  Once again, the legendary Spacewalk is available at AZFT.  As always, if you have any questions, please feel free to call us at 1-800-486-3996 or submit an inquiry through
