SEIKO Spring Drive starts its second year with two new creations, the Moon Phase and the GMT

For 2006, the international Spring Drive collection has been expanded to include two new calibers, expressed in three new references, and bringing the size of the total collection to nine watches. These additions provide a new vision of the 'circle' design concept that characterises the whole collection and yet maintain their own individual appeal.

The SEIKO Spring Drive Moon Phase

In another graceful expression of the natural and continuous motion of time, the silver color moon-shaped plate on the blue mother of pearl disc creates the serene and refined appeal of this elegant new timepiece, marking the continuous progress of the moon across the night sky.Not only the dial conveys the magical imagery of the moon. The movement itself is engraved to complete the harmony of the complete design, with the bridge and rotor portraying the fan-shaped pattern of moonlight radiating out from the glide wheel. The true and universal nature of time is thus represented in every part of the watch.It is offered as a limited edition of just 200, with the individual number engraved on the movement, visible through the sapphire case back.

The SEIKO Spring Drive GMT

With its high accuracy and complete energy autonomy, Spring Drive is the perfect watch for the traveler. With the addition of the 24-hour hand, the SEIKO Spring Drive GMT becomes the ideal timepiece for the international set. Time zone adjustment could not be more simple. Just by turning the crown, a different time zone can be set without affecting the precision on the second hand. The power reserve indicator is set deep into the dial to allow the time-of-day and 24-hour hand to glide over the dial surface, thereby maintaining the integrity of the original design.

SEIKO launches Spring Drive, the only watch in the world to represent the true motion of time.

Spring Drive is the most important new movement created by SEIKO since the quartz Astron in 1969. It is based on the foundation of all mechanical watch technology, a mainspring, but uses an entirely new system for time regulation that delivers the equivalent to 1 second per day accuracy, and, uniquely, glide-motion hands that represent the continuous, even motion of time. Spring Drive. The Quiet Revolution.
Spring Drive in numbers
Spring Drive is an important milestone in the history of watch-making, and will take its place alongside other developments like the creation of the escapement, the invention of the mainspring and the harnessing of quartz, as defining moments in the story of time. The launch of Spring Drive is a breakthrough moment for the science of timekeeping. Its technological advances are many and varied, as its numerical statistics reveal:

" 0.025 mm. The thickness of each layer of alloy in the coil block.
" 1 second a day accuracy, 10 times better than the chronometer mechanical standard.
" 3 types of energy are controlled by the Tri-synchro regulator: mechanical, electrical and electro-magnetic.
" 5 craftsmen and women. Only Seiko's 5 most skilled craftsmen and women are entrusted with the assembly of Spring Drive.
" 8 times per second. The precise speed at which the glide wheel turns within the electro-magnetic braking system.
" 13 generations of prototype were built in the development phases.
" 15 microns. The width of the wire in the Tri-synchro regulator's coil.
" 18 layers of amorphous alloy in the coil block.
" 25 nanowatts. The minute amount of power needed to activate the regulator, less than half that needed in all other watch circuits.
" 28 years of research and development invested in the project.
" 30 percent improvement in winding efficiency achieved through the improved Magic Lever system.
" 30 jewels in the movement. 32 in the small second hand version.
" 72 hours of power reserve. " 92 years since Seiko built its first wristwatch.
" 124 years of Seiko's expertise in time keeping.
" 230 patents have been applied for in Japan, USA and the EU.
" 276 components in the movement. 280 in the small second hand version.
" 600 actual prototypes were built between 1997 and 2004.
" 25,000. The number of times the coil is wound, for maximum energy efficiency.
" 28,800. The number of times the glide wheel turns per hour.
