Promaster Aqualand 40th Anniversary - Ltd Ed 5800pcs Ref. JP2008-06E

In 1985, Citizen made history with the launch of the world's first diver's watch featuring an electronic depth meter — the legendary Aqualand. Four decades on, Citizen proudly commemorates this groundbreaking innovation with a 40th Anniversary Limited Edition. A tribute to the original design that captivated professional divers and enthusiasts alike, this special release blends vintage charm with modern advancements. As part of the esteemed Promaster collection, it continues Citizen's legacy of pushing boundaries in professional sports watches, engineered for those who dare to explore the depths.

Let's talk presence. The Citizen Promaster Aqualand 40th Anniversary Limited Edition doesn't just rest on nostalgia; it commands attention with a case that's unapologetically bold. Crafted from stainless steel, the case measures 50.7mm across (including the unmistakable depth sensor at 9 o'clock), 47.3mm lug to lug, and 14.8mm thick, wearing with the confidence of a true professional diver's tool. The matte gray brushed finish sets the stage for serious underwater functionality, while gold-tone accents seen on the pushers and crown infuse it with a celebratory glow befitting a milestone piece.

Staying faithful to its groundbreaking predecessor from 1985, this limited edition brings back the original's iconic silhouette, from the bulbous depth sensor to the asymmetrical case design and the crown positioned at 4 o'clock. The three gold-tone pushers not only echo the original's layout but add a luxurious contrast against the utilitarian case. It also retains essential diver characteristics, including a unidirectional rotating bezel with a clear 60-minute scale, ensuring precise tracking of elapsed dive time. The gold-plated sides of the bezel feature a tactile pattern that provides excellent grip, even with gloves on. Rated to 200 meters of water resistance, this timepiece isn't just a collector's keepsake.

Beneath the mineral crystal, the black dial comes alive with a subtle radial sunburst effect, giving the watch an added sense of depth and energy. Large printed stroke hour markers offer excellent legibility, and the minute hand, rendered in a vibrant orange, stands out boldly — a thoughtful touch that reinforces its critical role in dive timing. Both the hands and hour markers are coated with luminous material for visibility in low-light conditions. In a nice detail, even the counterweight of the central seconds hand is lumed, showcasing Citizen's attention to functional finishing.

Multi-finished case

True to the Aqualand legacy, this model doesn't just tell time. It equips the wearer with vital dive data. The digital display seamlessly integrates with the analog design, offering access to time, calendar, alarm, and chronograph functions, while also providing depth measurement and dive time tracking when in dive mode. Adding to its professional functionality, it features an ascent rate alarm that sounds when the diver is surfacing too quickly, enhancing underwater safety. It's a clever fusion of analog charm and digital utility, staying loyal to the spirit of the original while embracing modern diving technology.

Powering all these advanced features is Citizen's in-house quartz Calibre C520, a reliable and purpose-built movement with an accuracy of ±20 seconds per month. All of this is securely housed beneath a screwed-in case back, which not only enhances water resistance but also adds a touch of commemorative pride. The case back is beautifully engraved with a logo inspired by the iconic shape of the depth sensor, a fitting tribute to this momentous 40th anniversary edition.

Citizen’s proprietary luminous glow in the dark

Completing the package is a black strap made from BENEBiOL™, a plant-based polyurethane material that reflects Citizen's commitment to both performance and sustainability. Selected for its resistance to hydrolysis when exposed to moisture, BENEBiOL is not only durable enough for marine environments but also carries a lower environmental impact compared to conventional materials. For added versatility, the watch includes a strap extension that allows it to be comfortably worn over a wetsuit. The strap is secured with a reliable pin buckle, combining practicality with comfort for everyday wear and diving adventures alike.

As a celebration of four decades of innovation beneath the waves, the Citizen Promaster Aqualand 40th Anniversary Limited Edition is both a nostalgic tribute and a fully capable modern dive instrument. With its bold design, professional-grade functionality, and thoughtful updates, it captures the spirit of the original 1985 Aqualand while meeting the expectations of today's divers and collectors. Limited to just 5,800 pieces worldwide, this commemorative timepiece is more than just a watch. It is a symbol of Citizen's pioneering legacy in dive watch history. Whether you're venturing into the deep or adding a milestone model to your collection, this is a fitting tribute to a true icon.
