What to know
Grand Seiko’s renewed Evolution 9 mechanical collection reaches its announced October release window with four references. The black-dial SLGH029 interprets a birch forest after dark, pairing its textured face with High-Intensity Titanium. It is part of the broader renewal announced in June, rather than a newly announced October design.
The 40 mm case is 11.7 mm thick and houses the automatic 9SA5 calibre. Grand Seiko specifies a 5 Hz frequency and approximately 80 hours of reserve, supported by twin barrels and its Dual Impulse Escapement. A revised clasp offers tool-free adjustment in three 2 mm steps. White, green and pale-blue mechanical variants complete the refreshed group; the photograph specifically shows SLGH029.
