Grand Seiko 37mm Spring Drive UFA Lake Suwa SLGB015 Review
The new Grand Seiko Spring Drive UFA Lake Suwa SLGB015 combines the most admired features of the Evolution 9 collection into a single 37 mm ever‑brilliant steel watch. It revisits the Lake Suwa dial pattern in a dark‑blue texture while retaining the classic hands, applied markers and date window seen on earlier titanium and platinum models. Housed in a compact case with a 44.3 mm lug‑to‑lug spread, the watch offers a comfortable 100 m water resistance, a screw‑down crown, and a sapphire‑crystal case back that showcases the ultra‑precise calibre 9RB2. This Spring Drive movement delivers an astonishing accuracy of ±3 seconds per month and a 72‑hour power reserve, with a visible indicator on the back. The bracelet features a three‑step micro‑adjustment clasp, allowing tool‑free fine tuning in 2 mm increments for a perfect fit. Released as part of the permanent collection in early September 2026, the SLGB015 is priced at €10 400, positioning it as a cornerstone model for enthusiasts who value both technical excellence and refined aesthetics.
