Citizen celebrates 40 years of underwater innovation with the Promaster Aqualand 40th Anniversary Limited Edition, a tribute to the 1985 model that introduced electronic depth meters to professional diving. This $595 limited edition retains the iconic design elements of the original while incorporating modern materials and a commitment to environmental responsibility.
The first Aqualand was a breakthrough in 1985, being the world’s first diver’s watch with an electronic depth meter. This innovation transformed professional diving by providing real-time depth data alongside standard timekeeping functions, setting a new standard for underwater instruments.
The anniversary edition closely mirrors the distinctive look that made the original famous. The crown is positioned at 4 o’clock, three push buttons are thoughtfully placed, and the round depth sensor at 9 o’clock echoes the original’s signature feature. The updated model uses a gray, brushed stainless steel case with gold accents, lending a celebratory feel for the 40th anniversary.
Technically, the new Aqualand maintains the pioneering spirit of its predecessor. The digital display shows time, calendar, alarm, and chronograph functions, and in dive mode, it measures depth and dive time. The ascent rate alarm warns divers if they ascend too quickly, enhancing safety during decompression.
The BENEBiOL™ polyurethane strap is made from plant-based materials, offering durability in water while reducing environmental impact. This eco-friendly approach underscores Citizen’s commitment to responsible manufacturing without sacrificing performance in marine environments.
Powered by the Cal.C520 movement, the watch operates within ±20 seconds per month and supports full digital functionality. The watch meets ISO standards for 200-meter water resistance, making it suitable for professional diving. It features luminous hands and markers, a unidirectional rotating bezel, a screw-down crown, and a 1/100-second chronograph with a 100-minute counter for precise underwater timing.
The case back features a special design inspired by the original sensor, adding a unique touch exclusive to this anniversary edition. Limited to 5,800 pieces and launching in July 2025, the watch is aimed at both diving professionals and collectors who appreciate technical innovation in timepieces.
At $595, the Aqualand 40th Anniversary Edition offers a chance to celebrate the history of electronic diving watches while delivering modern performance, proving that thoughtful evolution keeps classic technologies relevant and reliable. Find out more at www.citizenwatch.com.
