The SKYBRIDGE Spring Drive is a limited edition of 222 pieces, released exclusively in China. Although the case back is engraved with a number out of 222, Grand Seiko omitted all numbers containing the digit 4 due to its association with bad luck in certain cultures. As a result, only 182 pieces were actually produced.
Case: Brushed & polished stainless steel case. Sky blue dial with short brushstrokes pattern dial. Brushed & polished faceted hour & minute hands. Polished rose gold central seconds hand. Applied brushed & polished faceted index hour markers. Fine printed minutes/seconds track. Date window at 3 o'clock.
- Power Reserve Indicator:
- Located between 7 & 8 o'clock.
Bracelet & strap:
- Fitted on its original brushed & polished edges stainless steel bracelet with a push-button deployant clasp. The bracelet is fully linked & will fit up to an 8" wrist.
- Delivered with an additional original Grand Seiko blue alligator leather strap with a stainless steel push-button deployant buckle. The strap is unworn in brand new condition with its full wear life-span remaining.
Movement: Powered by a Grand Seiko Spring Drive caliber 9r65: The Spring Drive movement is for the most part mechanical, but with an electrical powered regulating mechanism resulting in an extremely accurate timepiece.
- No external source of power (such as a battery) is required.
- The unwinding force of the mainspring generates a slight electrical current. The electrical power is then used to activate & power a quartz oscillator which vibrates at 32,786 Hz & transmits a precise reference signal to the Integrated Circuit.
- The IC compares the speed from the oscillator to the speed of the glide wheel (which drives the gears) and applies a magnetic brake when it detects the glide-wheel turning too fast.
- The seconds hand moves in a continuous extremely smooth gliding motion and is accurate up to +/- 1 second per day.
- Contains 30 jewels & has an approximate power reserve of 72 hours (3 days).
Condition: In excellent near-new condition. We have had the watch very lightly & carefully spot-buffed to remove most light signs of wear that were present, however an effort was made to maintain the original factory 'zaratsu' finishing. We would now grade this watch at 96%+ overall condition. Delivered in its original box with the instruction manual (it does not have the factory warranty card).
