Seiko isn’t exactly afraid of color. Between bright Prospex divers, limited editions, textured Presage dials, and enough shades of blue to occupy their own Pantone book, the brand has given collectors plenty to choose from. Still, the new HBC011 Prospex 1965 Heritage Diver surprised me a bit. At first glance, this may be my favorite colorful Seiko release in recent years.
The new limited edition pairs a turquoise-blue bezel with a similarly vivid wave-pattern dial, all wrapped around Seiko’s familiar 1965 Heritage Diver platform. The color combination came from a global vote held in July 2025, when enthusiasts chose between four designs representing different times of day. “Daytime Blue” won, and 4,500 examples will go on sale beginning in October 2026.
The fan-voting exercise is interesting, though I’m mostly indifferent to how Seiko arrived here. Fans effectively selected a color direction for an existing watch. What matters more is that the winning combination works surprisingly well on a design that has spent much of its modern life looking backward. That’s where the HBC011 gets interesting.
The current 1965 Heritage Diver traces its basic design language to Seiko’s first dive watch from 1965, better known among collectors as the 62MAS. That connection has naturally resulted in plenty of restrained executions over the years. Black, gray, dark blue, and other vintage-adjacent treatments all make sense within that framework. Turquoise changes the conversation.
The matching dial and bezel give the watch a brighter, almost tropical personality, while the embossed wave pattern keeps the dial from looking like a simple color swap. Seiko says that texture references the wave mark historically associated with its divers, and similar dial treatments have appeared on recent Prospex limited editions. Here, however, the combination feels particularly well suited to the clean geometry of the 1965 Heritage Diver.
The rest is familiar territory. The stainless steel case measures 40mm across, 13mm thick, and 46.4mm lug-to-lug, with Seiko’s super-hard coating, a curved sapphire crystal, screw-down crown, and 300 meters of water resistance.
Inside is the automatic 6R55, offering approximately 72 hours of power reserve and a stated accuracy range of +25/-15 seconds per day. The bracelet also gets Seiko’s newer slide-adjusting clasp with 15mm of adjustment. Those details make the HBC011 a thoroughly modern interpretation of the 1965 design even before you get to the color.
The $1,400 price is another surprise. The standard black SPB453 sits at $1,300 in the U.S., leaving a $100 gap between the two. Considering the dial treatment, clasp, and limited production, Seiko has shown unusual restraint with the premium. And 4,500 pieces is enough that I wouldn’t get too distracted by the “limited edition” label. What stays with me is simply how much personality Seiko managed to pull from an extremely familiar platform. There have been plenty of colorful Seikos over the past few years, and plenty more limited editions. Few have grabbed me this quickly.
Of course, turquoise can be especially difficult to judge from press images, and seeing the HBC011 in person could change the equation. For now, though, this fan-selected Prospex may have produced my favorite colorful Seiko in recent memory, largely because the 1965 Heritage Diver seems so comfortable finally having a little fun.
