Grand Seiko Heritage Watch SBGA439G
A moonlit sky at night has a tantalizing and ever-changing hue which is captured perfectly in this midnight blue dial. Sometimes, the warmth of the blue is to the fore and, at others, the dial seems almost pitch black. Whatever its aspect, this dial is the perfect backdrop against which the diamond-cut hands and hour markers stand out in sharp relief.
