The 2026 Grand Seiko Evolution 9 UFA update refreshes the collection with eight updated references spanning both Spring Drive UFA and Hi-Beat 36000 models, alongside the new Lake Suwa UFA variants, all featuring revised cases, a redesigned bracelet, and Grand Seiko's long-awaited tool-free micro-adjustment clasp.
The new 40 mm Spring Drive UFA models measure 11.7 mm thick (with a new 37 mm Lake Suwa at 11.4 mm) and are powered by the Calibre 9RB2, delivering 72 hours of power reserve and an industry-leading ±20 seconds per year accuracy. The refreshed Hi-Beat 36000 models retain the Calibre 9SA5, offering an 80-hour power reserve, 36,000 vph beat rate, and the same updated bracelet and clasp across the lineup. Case materials include Ever-Brilliant Steel and High-Intensity Titanium.
