Pre-owned Grand Seiko Evolution 9 Collection ref. SLGA023 (2025) couples the brand’s Evolution 9 design language with the remarkable performance of its next-generation Spring Drive movement. The highlight is the striking blue “Ushio” dial, whose deeply textured pattern is inspired by the powerful ocean currents surrounding Japan. Paired with a matching blue ceramic bezel insert, the dial creates a dynamic, ever-changing appearance that shifts beautifully as it catches the light. Beneath the surface is Grand Seiko’s Spring Drive caliber 9RA5, delivering an impressive five-day power reserve and extraordinary accuracy of approximately ±10 seconds per month. The Evolution 9 case and handset were designed to maximize legibility, comfort, and durability, making this watch every bit as practical as it is beautiful. With its distinctive textured dial, cutting-edge movement, and exceptional finishing, the ref. SLGA023 is an outstanding choice for collectors who appreciate innovation without sacrificing the craftsmanship for which Grand Seiko is renowned.
