Four decades after revolutionizing underwater timekeeping, Citizen’s Promaster Aqualand returns with a commemorative edition that captures everything collectors love about the legendary “Pingo.”
Limited to 5,800 pieces at $595, this 40th Anniversary model resurrects the coveted two-tone aesthetic that made vintage Aqualands so desirable while packing the advanced digital dive capabilities that established the line as essential gear for serious underwater explorers. Available July 2025, this release proves that some innovations become more relevant with age, not less.
Deep Time
The Aqualand’s enduring appeal lies in its unique position as both nostalgic design icon and cutting-edge dive computer.
While modern smartwatches offer similar functionality through apps and connectivity, the Aqualand delivers dedicated dive instrumentation in a purpose-built package that doesn’t depend on software updates or battery-draining wireless features. This analog-digital hybrid approach creates a tool watch that feels both timelessly functional and refreshingly focused on its core mission.
At first glance, the 50.7mm width might seem intimidating, but the protruding depth sensor accounts for much of that measurement—the actual case wears like a 44mm watch with distinctive character.
The grey matte finish combined with yellow gold plating recreates the two-tone aesthetic that made certain vintage Aqualands so sought-after, while the black sunray dial provides perfect contrast for both analog and digital displays. This isn’t mere retro styling; it’s a thoughtful recreation of design elements that proved both functional and visually striking.
Digital Dive Technology
The heart of the Aqualand’s appeal remains its sophisticated depth measurement system, housed in the characteristic 9 o’clock protrusion that gives the watch its distinctive asymmetrical profile.
Beyond simple depth readings, the Cal.C520 movement provides comprehensive dive computer functionality including dive time tracking and ascent rate alarms—potentially life-saving features that separate this from typical dive watch offerings. The ability to cycle through time, calendar, alarm, and chronograph functions via the digital display creates versatility that modern divers genuinely appreciate.
Technical specifications reinforce the serious tool watch credentials: 200-meter water resistance, unidirectional dive bezel, and screw-down crown provide the foundation for professional underwater use.
The 14.8mm thickness accommodates the complex electronics while maintaining reasonable wrist presence, though this is clearly a watch that prioritizes function over discretion. The 24mm lug width provides substantial strap presence that matches the watch’s bold character.
The BENEBiOL™ biomass-based polyurethane strap represents Citizen’s commitment to environmental responsibility while delivering the quick-drying, salt-water resistant properties essential for dive watch use. The included strap extension ensures proper fit over dive suits—a practical detail that demonstrates understanding of how these watches actually get used.
Gold-toned printed indices and matching hour hand create visual cohesion with the yellow gold case elements, while luminous treatment ensures legibility in the low-light conditions where depth measurement becomes most critical. The sunray finish on the black dial adds premium visual interest that elevates the overall presentation beyond typical sports watch territory.
Perhaps most importantly, the $595 price point makes genuine dive computer functionality accessible to recreational divers who might otherwise choose between expensive dedicated computers or basic timing devices.
The 5,800-piece limitation creates collectibility without artificial scarcity, allowing enthusiasts to acquire a meaningful anniversary piece while ensuring broader availability for those who actually plan to dive with their Aqualand.
