Seiko Prospex 1965 Heritage Diver Fan-Selected Limited Edition Launches
Fans Choose the "Daytime Blue" Dial in Public Vote
Seiko has launched a new version of its popular vintage-inspired 1965 Heritage Diver, featuring a dial color selected by watch enthusiasts through a public voting process. The new HBC011 model, announced in August 2026, marks the 60th anniversary of the original 62MAS diver with a community-driven approach to design.
According to Hodinkee, Seiko presented fans with four variants of the watch, each inspired by different ocean tones throughout the day. The winning "Daytime Blue" color evokes the clear blue waters found in tropical locations under bright sunlight.
The Public Vote Process
Seiko launched the fan-selection campaign in 2025 to celebrate the 60th anniversary of the original 62MAS diver. The four options included:
- Daytime Blue - Clear tropical waters (winner)
- Bright Yellow - Sunrise tones
- Deep Green - Ocean depths
- Orange-Y Red - Sunset hues
The blue dial's victory was not surprising given its universal appeal, but each option represented a compelling take on the heritage diver concept. Seiko has not yet announced whether the other color options will receive production runs.
Technical Specifications
The HBC011 shares its specifications with Seiko's enthusiast-favorite SPB lineup of dive watches, specifically the '20MAS' generation released in 2024. This generation brought significant quality-of-life improvements including a refined case design and updated movement.

The 6R55 Movement
At the heart of the HBC011 is Seiko's 6R55 automatic movement, offering 72 hours of power reserve. The caliber provides hours, minutes, seconds, and date functions, with the date displayed at the 4:30 position — a design choice that has generated some discussion among enthusiasts.
The movement operates at 21,600 vibrations per hour (3Hz) and features 24 jewels, providing reliable timekeeping within Seiko's accuracy rating of -15 to +25 seconds per day.
Updated Clasp Design
One of the key improvements in the 2024 '20MAS' generation is the introduction of a new clasp with on-the-fly micro-adjustment. This feature, previously available only on more expensive dive watches, allows divers to adjust the bracelet length without tools — a significant practical improvement for underwater use.
The 1965 Diver Legacy
The 1965 Diver remains one of Seiko's most successful formats, striking a remarkable balance between vintage inspiration and modern sensibilities. The model line has become a cornerstone of the Prospex collection, appealing to both seasoned collectors and newcomers to watch enthusiasm.
According to Hodinkee, Seiko has done an excellent job iterating on the model, from major upgrades like the transition from SPB143 to SPB451, to smaller refinements between model generations.
Community Engagement Strategy
The fan-voting process represents an innovative approach to watch design that engages the collecting community directly. By involving enthusiasts in the decision-making process, Seiko created anticipation and investment in the final product before its release.
This strategy mirrors broader trends in the watch industry where brands increasingly seek to build direct relationships with their customer base through social media and community engagement.
FAQ
What made the Daytime Blue the winning color?
The blue dial's victory was consistent with broader trends in the watch market, where blue dials have become increasingly popular across all price points. The color evokes tropical ocean waters and offers versatile styling that works with both casual and formal attire.
How does the HBC011 differ from the SPB511?
The HBC011 shares the wave dial design and updated clasp with the SPB511, but features the fan-selected Daytime Blue colorway and removes the ghost bezel of the previous model. The core specifications remain identical.
Will other colors be released?
Seiko has not confirmed whether the other three color options (yellow, green, and orange-red) from the voting process will receive production runs. The brand may gauge market response to the HBC011 before making additional announcements.
