Seiko Prospex Limited Edition ‘Blue Fire Crater’ SPB543J
Limited Edition. 2,200 pieces worldwide. Special Box. Serial number selection is not possible as watches are sent at random.
The Seiko Prospex Sea Limited Edition “Blue Fire Crater” SPB543J draws its inspiration from the otherworldly blue flames seen in volcanic craters, translating this natural phenomenon into a powerful and distinctive dive watch. The deep blue dial captures this dramatic visual identity, complemented by a matching blue silicone strap and a robust stainless steel case. Limited to just 2,200 pieces worldwide, this edition blends rarity with Seiko’s long-standing professional dive watch heritage.
Inside the SPB543J beats Seiko’s in-house automatic Calibre 6R35, powered by the movement of the wearer and offering a substantial 70-hour power reserve. Designed for reliable everyday performance, the movement operates with an accuracy of +25 to -15 seconds per day within normal temperature ranges and includes hand-winding capability. An analogue three-hand display with a date window ensures clarity and practicality for both daily wear and extended adventures.
Built to meet professional diving standards, this model features 200-metre water resistance, a unidirectional rotating bezel with timer scale, and excellent legibility thanks to Lumibrite on the hands and markers. The 45mm stainless steel case is protected by a sapphire crystal and secured with a screw-down crown, while the durable blue silicone strap provides comfort and stability in wet conditions. Delivered in a special presentation box, each watch is individually numbered, reinforcing the exclusivity of this Prospex Sea limited edition.
