Collectors distinguish this reference from the earlier SLGH005 by its Spring Drive Caliber 9RA2, which provides a five-day power reserve and a movement accuracy of +/- 0.5 seconds per day. The 40mm stainless steel case follows the Evolution 9 design language, featuring a lower center of gravity and wider lugs for stability. The dial utilizes a pressed pattern inspired by white birch forests in Shizukuishi, characterized by shallower, more subtle textures than its high-beat predecessor. On the secondary market, the SLGA009 typically trades between $6,500 and $8,000 depending on condition and completeness. A notable technical distinction of this reference is the relocation of the power reserve indicator to the caseback side, resulting in a more symmetrical dial layout compared to previous Spring Drive models."}, "listing_stats": {"count": 4, "median": 6450.0, "low": 6150.0, "high": 100000.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_8035586965826", "title": "Grand Seiko Evolution 9 Spring Drive 'White Birch' 40mm SLGA009", "brand": "Grand Seiko", "model": "Evolution 9 Spring Drive 'White Birch' 40mm SLGA009", "reference": "SLGA009", "price_usd": 100000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "watch-affinity", "merchant_name": "Watch-Affinity", "image_url": "https://cdn.shopify.com/s/files/1/0683/2449/1586/products/18400337_1.jpg?v=1669845260", "detail_url": "https://mostexpensivewatches.net/listing/h_8035586965826", "buy_url": "https://mostexpensivewatches.net/out/h_8035586965826", "available": false}, {"id": "h_6934830252107", "title": "Grand Seiko Grand Seiko Evolution 9 Hi-Beat 36000 White Birch SLGH005", "brand": "Grand Seiko", "model": "Grand Seiko Evolution 9 Hi-Beat 36000 White Birch SLGH005", "reference": "SLGH005", "price_usd": 6450.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/Grand-Seiko-Evolution-9-Hi-Beat-36000-SLGH005-10-10-GRS-85MCA1-372b99fedaa3.jpg?v=1707575566", "detail_url": "https://mostexpensivewatches.net/listing/h_6934830252107", "buy_url": "https://mostexpensivewatches.net/out/h_6934830252107", "available": false}, {"id": "h_6863537471563", "title": "Grand Seiko Grand Seiko Evolution 9 Hi-Beat 36000 White Birch SLGH005", "brand": "Grand Seiko", "model": "Grand Seiko Evolution 9 Hi-Beat 36000 White Birch SLGH005", "reference": "SLGH005", "price_usd": 6450.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/Grand-Seiko-Evolution-9-Hi-Beat-36000-SLGH005-10-10-GRS-RSZC95-d6c6f0a720c3.jpg?v=1698521309", "detail_url": "https://mostexpensivewatches.net/listing/h_6863537471563", "buy_url": "https://mostexpensivewatches.net/out/h_6863537471563", "available": false}, {"id": "h_6859040817227", "title": "Grand Seiko Grand Seiko Evolution 9 Spring Drive SLGA009", "brand": "Grand Seiko", "model": "Grand Seiko Evolution 9 Spring Drive SLGA009", "reference": "SLGA009", "price_usd": 6150.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/Grand-Seiko-Evolution-9-Spring-Drive-SLGA009-10-10-GRS-V9ZHMU-2991c3957154_22bea815-4b59-431c-9d79-1fe9c34d3530.jpg?v=1701113760", "detail_url": "https://mostexpensivewatches.net/listing/h_6859040817227", "buy_url": "https://mostexpensivewatches.net/out/h_6859040817227", "available": false}], "auction_lots": []}
