Notes: Representing the pinnacle of mechanical watchmaking from Shizukuishi Watch Studio, the reference SBGH005 is one of Grand Seiko’s most celebrated modern creations. Housed in a classic 40.2mm stainless steel case executed with Zaratsu distortion-free polishing, this timepiece features a deep black dial with subtle radial sunburst finishing inspired by the ridges of Mount Iwate. Powered by the legendary high-frequency Calibre 9S85 automatic movement beating at 36,000 vibrations per hour, this 12/2025 papered example is offered in mint condition as a complete set.
Condition Assessment:
Overall Condition: Pre-Owned - Mint; the case and bracelet exhibit flawless factory lines and razor-sharp bevels throughout, showing virtually zero signs of wear across all Zaratsu mirror-polished and satin surfaces.
Dial, Hands, & Crystal: The deep black radial sunburst dial, razor-sharp hands, and multi-faceted applied hour markers are in pristine condition. The dual-curved high-definition sapphire crystal with inner anti-reflective coating is completely clear and defect-free.
Case & Bezel: The 40.2mm stainless steel case and fixed bezel retain flawless geometry with zero scratches, dings, or scuffs. The screw-down crown with engraved GS logo operates crisply and smoothly.
Strap/Bracelet & Clasp: The solid three-link stainless steel bracelet retains total structural rigidity with zero stretch, fitted with its original three-fold clasp with push-button release.
Technical Specifications:
Reference: SBGH005
Case Size: 40.2mm
Case Material: Stainless Steel
Dial: Black Radial Sunburst Dial with Applied Multi-Faceted Indices and Date Window at 3 o'clock
Movement: In-house Automatic Hi-Beat 36000 Calibre 9S85
Power Reserve: Approximately 55 Hours
Water Resistance: 100 Meters / 10 ATM
Notable Details: High-frequency 36,000 vph (10 beats per second) movement; Spron 610 mainspring and Spron 530 balance spring alloys; MEMS-manufactured escapement components; Zaratsu mirror-polishing technique; sapphire exhibition caseback.
What Makes the Heritage Collection Special:
The Grand Seiko SBGH005 holds a landmark position in modern Japanese watchmaking history. Introduced as the benchmark model to showcase Grand Seiko's mechanical resurgence, it re-established the Maison's high-frequency capability—a legacy that dates back to the historic 1968 Calibre 61GS. Encased in an architecture that directly honors the legendary 44GS design grammar of 1967, the SBGH005 highlights flat surfaces and sharp angles designed to interact with light and shadow in perfect balance.
At the heart of the SBGH005 is the high-beat Calibre 9S85, operating at an astonishing 36,000 vibrations per hour (10 beats per second). Beating 20 percent faster than standard mechanical watch movements, this high-frequency rate delivers exceptional resistance to external shocks and superior rate stability. To achieve this while maintaining a robust 55-hour power reserve, Grand Seiko engineers utilized Micro-Electro-Mechanical Systems (MEMS) precision technology to manufacture featherweight escapement parts alongside proprietary Spron alloys for the mainspring and hairspring.
The visual hallmark of the SBGH005 is its rich black dial, which features a subtle radial pattern inspired by the dramatic topography of Mount Iwate, visible through the windows of the Shizukuishi Watch Studio where the piece was assembled. Combined with hand-polished Zaratsu mirror surfaces that reflect light without distortion, the SBGH005 stands out as an absolute titan of Japanese haute horlogerie.
