About the Elegance family
Elegance is Grand Seiko's dress collection, with slimmer cases, refined dials often inspired by Japanese seasons and nature, and many hand-wound models. It is the line for buyers who want a classic watch rather than a sporty one.
The references in this catalog cover mechanical models with the hand-wound 9S63 and 9S64 calibers, hand-wound Spring Drive with the 9R31, automatic Spring Drive and quartz with the 9F61, mainly in steel. Dial texture and colour are central to each reference, so match them carefully, and check the case for over-polishing.
