SEIKO Spring Drive Spacewalk Seiko unveils the SEIKO Spring Drive Spacewalk watch at the BaselWorld 2008, which will go into Space in October.

In October 2008, Richard Garriott, the renowned video game designer and adventurer, will become the sixth private space explorer. Richard will conduct his space mission aboard the International Space Station, and during his flight, he intends to conduct a spacewalk, which would make him the first private individual to do so. As steps out into free space, he will be wearing a SEIKO Spring Drive watch, specially designed and built for this purpose.

The first decision to be made was on the type of movement to be used. Without special treatment, battery-operated instruments are not appropriate for a spacewalk for safety reasons. Thus, quartz movements were not considered. The choice was therefore between mechanical and Spring Drive. The choice was decided by the need for safety and accuracy. As the watch will be exposed to a range of temperature from minus 20 degrees Celsius to plus 70, accuracy at extreme temperatures was the critical factor, and no mechanical watch can retain its accuracy in these conditions, because of the inherent instability in these conditions of the traditional escapement which regulates the time in all mechanical watches. Instead of a traditional regulator, Spring Drive has a Tri-synchro Regulator, an entirely new regulator that uses and generates mechanical, electrical and electromagnetic power, and is less affected by temperature variations. Thus, Spring Drive was selected as the perfect mechanism for the task.

The SEIKO Spring Drive Spacewalk has been custom designed and built with Richard's mission in mind. The mission of SEIKO's engineers was to build a watch that was light, air-tight, strong, easy to read and easy to use, as well as safe and accurate.
