Source note

Added 2026-08-06. Specs confirmed via Seiko USA (seikousa.com/products/srpe57), Seiko Watch Corp official site, and retailer listings (Long Island Watch, 5seeker). Stock crystal is Hardlex (confirmed -- sapphire is a common aftermarket mod for this case family, not stock). MSRP $315 is Seiko USA's own list price, not a retailer estimate. Also sold under SRPE57K1 / SBSA047.
