The “Ice Forest at Dawn” Spring Drive U.F.A.

 

Last year, Grand Seiko introduced its groundbreaking Calibre 9RB2 – with an annual deviation of only ±20 seconds – in two variants of the Evolution 9 line: 

  • one in platinum (SLGB001) 
  • and one in titanium (SLGB003).

This new ref. SLGB006 offers an 18k yellow gold version. 

Note that UFA stands for “Ultra Fine Accuracy”.



The jet-black dial inspired by an “Ice Forest at Dawn” features innumerable gold-colored specks realized through a coating technique. 



According to Grand Seiko, “their effect on the dial is reminiscent of a sun  pillar, a phenomenon that can be observed on winter mornings when emerging sunlight reflects off ice crystals suspended in the air to create the illusion of a towering pillar of light.”



The case measures a rather compact 37 x 11.4 x 44.3 mm.



The Spring Drive U.F.A. (“Ultra Fine Accuracy”) caliber 9RB2 isn't visually appealing, but it provides an annual accuracy of ±20 seconds.



The applied faceted markers have a strong presence, especially the large one at 12 o'clock, but I find the overall look of this watch very nice.



The SLGB006 is a limited edition of 80 pieces, which will be available in June 2026 at Grand Seiko Boutiques.



I know that not much attention will be paid to this release, but I find it interesting and quite appealing...



... and I like it much more than the platinum and titanium Spring Drive U.F.A. from last year.

And the titanium SLGB003 with its light blue hue “Shinshu Ice Forest” dial:



How do you feel about the new yellow gold SLGB006?

Do you share my interest?

Do you prefer the platinum or the titanium variant?
