For 2023, Citizen has introduced two new versions of its so-called “Ecozilla” dive watch.

The Citizen Promaster Dive “Ecozilla” comes in a sizable 48 mm diameter by approximately 17 mm thick stainless steel case made for diving. There are two new models, one in untreated stainless steel and the other in black DLC-treated stainless steel, the latter being extra resistant to scratches thanks to the coating.

Along with the oversized case are extra large hour markers and hands, which are coated with a generous amount of lume for excellent legibility. The date has been cleverly integrated into the 3 o’clock index, without clashing with the aesthetic.

Everything, from the knurled crown, located on the left case flank, and protected by crown guards, to the caseback, is sealed with a gasket, and the resulting depth rating is 300 meters. The rotating unidirectional dive bezel has engraved numerals and a lume pip and twelve, and because of the sheer size of the watch, can be operated, even with gloves on.

Driving the three hands and date is Eco-Drive caliber B873, which is powered by light that enters through the dial, and is accurate to +/- 15 seconds per month, much like Casio’s Tough Solar quartz movement technology. The “Ecozilla” name was derived from the similarities to the original “Autozilla” and due to the fact that this model has an Eco-Drive movement.

The Promaster Dive Ecozilla (Ref. BJ8058-06L – stainless steel case/yellow strap, BJ8057-09X – DLC-coated stainless steel/green strap) comes with a shatter-resistant mineral crystal that protects the dial and offers a clear view of the dial thanks to an anti-reflective treatment. A bright yellow or military green polyurethane strap with a stamped stainless steel pin buckle is paired with the respective model. The caseback is embossed with a diving helmet motif.

Retail is $595 for the stainless steel version and $675 for the DLC-coated stainless steel model.
