Seiko Prospex HBC011J 1965 Diver Heritage Fan Select Limited Edition Wristwatch

The Seiko Prospex 1965 Diver Heritage Fan Select Limited Model HBC011J is the result of something unusual in Seiko's history: a collaboration with the people who wear the watches. The dial colour and design direction were determined by fan vote — a direct consultation with Seiko's collector community that produced a result no internal design process would have arrived at alone. The outcome is a watch that feels genuinely owned by its audience: a stone grey dial whose graduated depth shifts from the periphery inward, an applied Prospex logo in black, Lumibrite-filled sword indices that catch light with the clarity of a dive instrument, and an anti-rotation 60-minute graduated bezel in matte black. The case is the Heritage Diver form — a direct descendant of the 1965 150M Diver, Seiko's first diver's watch, with the distinctive cushion-shaped silhouette that defines the lineage. Caliber 6R55, 72-hour power reserve, pure titanium construction with Dia-Shield coating throughout, curved sapphire crystal with inner anti-reflective coating, screw-lock crown, screw caseback with "LIMITED EDITION" and individual serial number. Water resistant to 300 metres. World limited to 4,500 pieces with 2,000 allocated domestically in Japan. Available exclusively through Seiko Global Brand Core Shops worldwide. Releasing October 2026.

*Pre-Order! Estimated release and shipment from October 2026.*

Key Features:

• Fan-Selected Dial — A Direct Vote from the Collector Community: The stone grey dial colour and overall design direction of the HBC011J were determined by fan vote — a genuine consultation between Seiko and its collector audience that is reflected in every design decision on this watch. The result is a dial that resonates with the people who actually wear Prospex divers, rather than with a design brief written at a remove from that community.
• 1965 Heritage Diver Architecture — 300m Water Resistance: The cushion-shaped case directly references the 1965 150M Diver — the watch that established Seiko's diver lineage and set the proportional template that the Heritage Diver series continues today. The anti-rotation 60-minute graduated bezel, screw-lock crown, and 300-metre water resistance confirm this as a fully functional professional dive instrument, not a dress watch in dive clothes.
• Caliber 6R55 — 72-Hour Power Reserve: 24 jewels, approximately 72 hours of power reserve on a full wind, automatic with hand-winding, hacking seconds, ±25/−15 seconds per day. The movement is visible through the curved sapphire crystal screw caseback, which carries the "LIMITED EDITION" marking and individual serial number.
• Pure Titanium Dia-Shield — Curved Sapphire with Inner AR Coating: The case is machined from pure titanium and finished with Dia-Shield — exceptional scratch resistance, significantly lighter than stainless steel, and nickel allergy resistant. The curved sapphire crystal features inner anti-reflective coating for maximum legibility underwater. Lumibrite on all hands, indices, and bezel pip for dark-water visibility.
• Seiko Global Brand Core Shop Exclusive — World Limited 4,500: Available only through Seiko's designated Global Brand Core Shops worldwide, with 2,000 pieces allocated to Japan. The Core Shop exclusivity combined with the 4,500-piece world limit ensures genuine scarcity for what is already a historically significant model in the Heritage Diver lineage.
