Citizen did not disappoint. The Citizen Promaster Eco-Drive Professional Diver 1000m (Reference BN7020-09E) is the world’s first solar-powered saturation capable diving watch. It is also Citizen’s second 1,000 meter diver. This watch is one of the few watches that can be define as an extreme dive watch. It is capable of exceptional depth and not suited for formal wear. It has been given the nickname “Solarzilla”.
The Solarzilla follows the design philosophy of its predecessor, the Autozilla. Slightly larger than the Autozilla, the Solarzilla is different in a few aspects. First, it is an Eco-Drive instead of automatic. Second, the new diver comes with an additional locking system that has a visual indication to show when the timing bezel is unlocked. Third, the addition of a power reserve reserve indicator.
