One of Holden’s Grails
Grand Seiko Elegance Iwao Blue
The Grand Seiko Elegance Iwao Blue (SBGY043) is a dress watch from Grand Seiko: a 38.5 mm stainless steel case, 10.2 mm thick and 43.7 mm lug to lug, with a manual 9R31 movement.
Going by its 43.7 mm lug to lug, it should sit within the flat top of a wrist of about 5.9 inches (15.1 cm) or larger.
Research found it at $9,800 list in the US (checked August 2026).
The same thin Elegance case as the Omiwatari, with the blue Iwao dial.

- First bracelet execution in this line — more wearable day-to-day than croc [2]
- Deep indigo iwao texture with diamond-cut furniture [2][4]
- No-date purity retained [4]
Weaknesses
- Full-retail proposition: boutique exclusive, $9,800, no used market to exploit [1][2]
- Splash-resistant only, despite the sportier bracelet framing [1]
- Bracelet micro-adjust and taper undocumented so far
- Too new for long-term owner data
