**Background and History of the Grand Seiko 9587-8000**
**1. The Relaunch of Grand Seiko (1980s)**Grand Seiko began its history in 1960. While it pursued high precision through mechanical movements in the 1970s, the brand was revived in 1988 with high-precision quartz models.
The quartz models of this era, particularly the "95GS" series, are positioned as the first quartz watches to officially bear the "Grand Seiko" name (distinguishing them from the Grand Quartz of the 1970s).
**2. Features of the 9587-8000 (SBGS003)**The 9587-8000 is a quartz model from the Caliber "95GS" series, also known as the SBGS003.
Released in 1988, it features well-balanced dimensions with a 37mm diameter, a thickness of approximately 8mm, and a lug-to-lug distance of 42mm.
The movement is equipped with a **thermo-compensated quartz (Caliber 9587)**, boasting high precision with an annual accuracy of ±10 seconds.
**3. Collector Evaluation and Popularity**As a neo-vintage piece, the thin profile and understated champagne dial are particularly popular. It is highly regarded for balancing practicality with a refined design.
It is highly rated among collectors and strongly recommended as a model that excels in durability, design, and wearability.
**4. Market Trends and Pricing**In the secondary market, it typically circulates between 90,000 JPY and 120,000 JPY. Due to its popularity, listings tend to sell out quickly.
Furthermore, its valuation is relatively stable compared to the overall market and brand averages, showing relatively gradual price movements of +3.6% over the past year and -1.8% over the past five years.
**5. Manufacturing Year and Specifications (Supplementary)**According to Reddit posts, a unit manufactured in January 1991 was noted to have a 36mm case and 7mm thickness, suggesting that units of this generation were produced from their debut in 1988 through the 1990s.
Additionally, there are recorded sales of units manufactured in 1992 featuring a gold (cream) dial, complete with the original box and warranty papers.
