Why SEIKO Spring Drive? The challenge ofa watch that could operate not only during a space flight but also outside on a spacewalk is a daunting one, and is precisely the kind of challenge that brings out the best in SEIKO's engineers. The very first decision to be made was on the type of movement to be utilized. Without unique Replica Baume & Mercier 8345 Hampton Men's Watch 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 Replica Baume & Mercier 8427 Hampton Ladies' Watch. 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 Spring Drive Spacewalk.The SEIKO Spring Drive Spacewalk has been custom created 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. (i) The air-tight case Because of the vacuum of free space, the watch case needs to be completely air-tight. Based on SEIKO's long experience with Divers Replica Baume & Mercier MOA8669 Riviera Watch Men's that can withstand pressures up to 1,000 meters, Spacewalk was created with unique features that will guarantee air tightness.In addition, to maintain the air-tightness in the huge temperature changes that occur in the vacuum of free space, and especially in cold temperatures, it was necessary to develop a new type of gasket using a rubberized material.
