Introducing Grand Seiko Introduces the Evolution 9 Moonlight Birch

Grand Seiko’s Birch series first debuted in 2022 with the inaugural white-dial version. Since then, the collection has expanded with several variations. That design now returns in stainless steel with a navy blue dial, unveiled as the Grand Seiko “Moonlit Birch.”

The watch is housed in a stainless steel case measuring 38.6mm in diameter, 45.0mm lug-to-lug, and just 9.95mm in thickness, giving it an elegant and refined profile. A box-shaped sapphire crystal with anti-reflective coating on the inner surface ensures excellent legibility while maintaining a classic look. 

The see-through sapphire caseback, secured by four screws, reveals the finely finished movement within, adding a modern touch to the timeless design. With its slim proportions and narrow bezel, the case embodies the understated elegance characteristic of a Grand Seiko dress watch.

The navy blue dial is described by the brand as “an ode to the moonlight scene of Iwate’s birch trees,” near the birthplace of mechanical Grand Seiko timepieces and the Hiraniwa Plateau, known for its vast white birch forests. These trees have long served as a source of inspiration for Grand Seiko, and here, the dial’s intricate and irregular texture takes on a deep navy hue, “expressing the beauty of white birch trees appearing faintly in the moonlight.”

True to Grand Seiko’s philosophy of simplicity, the dial retains a clean and symmetrical layout, with polished steel hands and applied indices. To preserve this balance, the power reserve indicator has been discreetly placed on the movement side.

Powering the watch is the in-house, manual-winding Calibre 9SA4, a high-beat movement operating at 5Hz (36,000 vibrations per hour). It delivers precision with an accuracy rating of -3/+5 seconds per day. Designed for long-term stability, the movement is equipped with twin barrels that provide a generous 80-hour power reserve.

Completing the watch is a cow leather strap that matches the dial in both texture and tone, secured by a stainless steel three-fold deployant clasp.

The Grand Seiko Evolution 9 Moonlit Birch joins the brand’s permanent collection, priced at EUR 10,200, equivalent to AED 43,900.
