              The Seiko Presage SPB529J1 embodies a masterful blend of Japanese heritage and modern craftsmanship. Its 40.2 mm stainless steel case is 13.0 mm thick and measures 46.0 mm lug-to-lug, striking a balance between elegant presence and day-to-day wearability. The gradient Shiracha dial, inspired by the soft brown tones favored during Japan’s Edo period, merges subtle heritage cues with rich visual depth.
Powered by Seiko’s in-house Caliber 6R55 automatic movement, this timepiece offers approximately 72 hours of power reserve, manual winding capability, and accuracy rated at +25 to –15 seconds per day. The dual-curved sapphire crystal with inner anti-reflective coating ensures clarity and protection. With water resistance of 10 bar (100 meters) and a see-through screw case back engraved with “Limited Edition,” it celebrates exclusivity while delivering practical performance.
