Introducing the Japan Grand Seiko boutique exclusive model, the SLGA003, equipped with a whole new Spring Drive caliber "9RA5" with a very limited production of 60pcs only to celebrate the 60th anniversary of the brand's birth.
The "Spring Drive 5 Days" is an evolution of "9R Spring Drive" that was born in 2004. It is a new-generation spring drive movement that is thinner and stronger than ever GS has produced.
The conventional Spring Drive has a maximum hoisting time of about 72 hours (3 days), this model equipped with the "9RA5" now using a newly developed two barrels design, the maximum hoisting time can be extended to around 120 hours (5 days), which greatly improved the long-lasting sustainability.
On the dial is a very beautiful and subtle deep green accented by golden yellowish highlights on the inner marker rim and seconds hand. The case design and polishing are finished by "Zaratsu polishing" as performed by a skilled polisher.
An extra reinforced silicone strap is included with matching green colour to the dial. The "Limited Edition" and serial numbers are engraved at the case back to mark the rarity of this incredible timepiece.
