Japanese watchmaker Citizen has unveiled the latest addition to its professionally-focused Promaster line, the new Promaster Eco-Drive Aqualand 200m.

Its robust 50.4-mm steel case has a three-piece construction that imparts it a hardy and unique silhouette, flanked on one side by two chronograph pushers and a knurled screw-down crown, and on its other by a depth-gauge sensor. The depth gauge sensor in particular is a very interesting feature, as it not only gives the watch an additional functionality beyond timekeeping but also hearkens back to the original Aqualand unveiled in 1985 (below), which at the time was the first watch to feature a depth gauge with an electronic sensor.
The other details of the 200-meter water-resistant case include a bold-looking 60-minute unidirectional diving bezel, where we find the first major pop of color: its three three distinct colorways are blue, DLC red, and DLC green.
