Why the "Ecozilla"?
Nicknamed for its massive, overbuilt construction and unstoppable Eco-Drive power system, this is the watch that earned a cult following among serious divers, collectors, and watch enthusiasts.

Eco-Drive Technology:
Citizen's proprietary Eco-Drive movement converts any light — sunlight, office fluorescent, LED — into electrical energy stored in a rechargeable cell. Once fully charged, the B873 caliber can run for up to 6 months in total darkness. No battery changes. No winding. Sustainably powered for the life of the watch.

Dive-Ready Engineering:
This is not a fashion diver — it is a professional-grade dive instrument. The 300-meter depth rating, screw-down crown, screw-back case, and 6mm crystal are engineered to maintain structural integrity under extreme underwater pressure. The left-side crown placement prevents wrist interference during diving operations. The unidirectional bezel clicks positively and can be operated with gloves or in cold water.
