CITIZEN PROMASTER
Marking 40 Years of the Aqualand Legacy: Citizen Launches a Limited Edition Tribute to the World's First Electronic Depth-Sensing Diver's Watch
The CITIZEN PROMASTER line of professional sports watches offers superior functionality to ignite the imagination. The latest release from the PROMASTER lineup is the "Aqualand 40th Anniversary Limited Edition," which commemorates the 40th anniversary of the world's first diver's watch equipped with an electronic depth meter.
In 1985, Citizen launched the world's first diver's watch equipped with an electronic depth meter, called the "Aqualand." This year, marking the 40th anniversary of its release, Citizen introduces a limited edition model that is a faithful yet contemporary tribute to the original design.
The crown at the 4 o'clock position, three push buttons, and the distinctive bulbous depth sensor at the 9 o'clock position replicate the shape of the original model.
The case features a gray matte brushed finish, while gold accents give it a special appearance befitting a 40th anniversary model.
In addition to displaying the time, calendar, alarm, and chronograph functions, the digital display also allows for depth measurement and dive time tracking in dive mode. It is also equipped with an ascent rate alarm function that sounds a warning when the ascent speed exceeds a certain limit.
The strap is made of BENEBiOL™*, a plant-based polyurethane. CITIZEN has adopted BENEBiOL for its straps as it is resistant to hydrolysis when exposed to moisture and has a lower impact on the environment.
The case back is engraved with a logo inspired by the iconic shape of the sensor to celebrate this momentous occasion.
