Grand Seiko Updates its Classic Evo9 Collection Models with Spring Drive UFA Calibre and new Bracelet
Grand Seiko has updated its Evolution 9 collection with new Ever-Brilliant Steel cases and improved, more tapered bracelets. These mechanical and ergonomic refinements apply to the White Birch, Atera Valley, and Lake Suwa models.
Why it matters
This update addresses long-standing consumer feedback regarding bracelet comfort and material durability in luxury watchmaking.
What we re looking at now are evolutions of three existing watches: the White Birch SLGA009 , the Atera Valley SLGA025 and the Lake Suwa SLGA007 . All of these watches have been strong sellers for the brand and instrumental to its recent success. Based on the Evolution 9 style , all three were powered by the proprietary Spring Drive technology and the calibre 9RA2, a movement that marked a substantial upgrade over previous movements, such as the 9R6x architecture. But Grand Seiko decided to give these models some upgrades, mechanically and in terms of comfort.
