What is it? Grand Seiko’s latest Ninjutsu-inspired collection!
This just in! Grand Seiko has revealed a brand new collection consisting of two models. The first of the duo is titled the Grand Seiko Ninja Spring Drive while the second is dubbed the Grand Seiko Kunoichi Automatic. The former, as you can tell, is aimed at men while the Kunoichi is designed for ladies.
While technical specs and dimensions remain a mystery for now, we know that the Ninja Spring Drive is based on the Grand Seiko ‘Snowflake’ SBGA211G. That means you’ll get the same 9R65 Spring Drive movement that is accurate to +/- 1 second per day. Power reserve is a healthy 72 hours.
The most notable feature on the both the Ninja and Kunoichi models are the Shuriken-like appendages on the case. Though the ‘blades’ are Zaratsu polished, Grand Seiko states that it “will never accidentally hurt or scratch anyone.” Ninjutsu practitioners, however, can utilise the watch to hurt someone on purpose.
Moving on, the Grand Seiko Kunoichi Automatic is based on the reference STGK002J. As such, expect a case fashioned out of 18K rose gold and a bezel with 37 diamonds. Inside the watch beats Seiko’s 9S25 calibre with 33 jewels. The movement boasts an accuracy of +8/-3 seconds per day and has a power reserve of 50 hours.
About Seiko’s Spring Drive
For those who are unfamiliar with Seiko’s Spring Drive, it is, in short, a combination of the best bits of a quartz and mechanical movement. Seiko first introduced Spring Drive in 1999 after two decades of R&D. In Seiko’s words, it “combines the power derived from a mainspring with the high accuracy of a quartz crystal.” Visually, Spring Drive movements possess an impossibly smooth sweeping seconds hand due to the nature of the calibre.
Speaking to Centre Seconds, sources close to Grand Seiko have revealed that the Ninja and Kunoichi are available on a made to order basis starting on April 1 2018. I repeat, April 1 2018. Prices for the Ninja and Kunoichi begin at Ƀ277,451.
