Kirazuri-Inspired Dials: A Tribute to Japanese Artistry
Unique Dial Design
The dials of the SBGA507 and SBGA509 are inspired by Kirazuri, a traditional Japanese woodblock printmaking technique that uses mica powder to create a textured, sparkling effect.
This artistic approach gives the dials a distinctive, elegant appearance that catches and reflects light beautifully.
Color Variations: Lake Suwa Inspirations
The SBGA507 features a “cool blue” dial, inspired by the evening skies over Japan’s Lake Suwa, while the SBGA509 boasts a “dusty rose” hue, reminiscent of the sunrise above the same lake.
These color choices add a layer of elegance and uniqueness, making each watch a conversation piece.
Under the Hood: The Spring Drive Movement
Caliber 9R65: Precision and Power
Both limited edition watches are powered by Grand Seiko’s Caliber 9R65 Spring Drive movement.
Celebrating its 20th anniversary, this movement offers a 72-hour power reserve, 30 jewels, and an impressive accuracy of +/- 15 seconds per month.
The movement can be admired through the watches’ exhibition case backs, adding to their allure.
Power Reserve Indicator
The power reserve indicator is strategically placed at the 8 o’clock position, providing a clear view of the remaining power.
This practical feature ensures that the wearer is always aware of the watch’s status, enhancing the user experience.
Heritage Collection: A Legacy of Excellence
Attention to Detail
Grand Seiko is known for its attention to detail, and the SBGA507 and SBGA509 are no exceptions.
From the silver dauphine-style hands to the rectangular hour markers and the black-on-white date window at 3 o’clock, every element is carefully designed for both functionality and aesthetics.
