Grand Seiko has unveiled two headline releases for collectors and enthusiasts: the SLGW007 dress watch and a new Tentagraph, the SLGC006. Both pieces spotlight the brand’s hallmark high-frequency watchmaking and meticulous finishing, while offering distinct personalities—one refined and understated, the other bold and technical.
The SLGW007 is a direct follow-up to last year’s highly regarded dress models, now rendered in stainless steel while keeping the elegant proportions that made its predecessors so wearable. The case remains a svelte 38.6 mm in diameter and just 9.95 mm in height, delivering classic dress watch sizing with razor-sharp polishing and crisp case lines. Its textured navy dial is inspired by white birch bark under moonlight, pairing organic depth with a rich, nocturnal hue. The layout is minimalist and balanced, with dauphine-style hands, faceted hour markers, and the brand’s signature at 12 o’clock.
Inside is the debut of Caliber 9SA4, a new high-frequency, manual-wind movement that beats at 10 vibrations per second (36,000 vph) and stores an impressive 80-hour power reserve. This combination of a hand-wound architecture and Hi-Beat precision is a compelling proposition for purists who value both tactile winding and cutting-edge performance. The watch is fitted with a matching textured navy leather strap featuring a three-fold clasp with push-button release for security and comfort. The SLGW007 is priced at $10,000, with availability scheduled for October 2025.
Alongside the dress piece, Grand Seiko introduced the latest Tentagraph, the SLGC006. This high-frequency mechanical chronograph leans into sport-luxe elegance with a copper-pink dial bearing the distinctive Mt. Iwate pattern. The contrast of warm dial tones with premium materials gives it standout presence on the wrist. Its case and bracelet are crafted from high-intensity titanium for strength and lightness, while the bezel, crown, and chronograph pushers are rendered in 18K rose gold, adding a rich, elevated touch.
Powering the SLGC006 is the 9SC5 Hi-Beat 36000 chronograph caliber, delivering precise timing performance and a 72-hour power reserve—a robust spec for a high-frequency chrono. The new Tentagraph is a limited edition of 100 pieces, priced at $22,600, and will be available in October 2025.
