Overview
The Citizen BJ8050-08E, famously known among enthusiasts as the "Eco-Zilla," is an iconic, ultra-robust diving instrument engineered for saturation diving and extreme underwater environments. Part of the Promaster Sea collection, this watch is defined by its massive, reinforced stainless steel "tank" construction and its unmistakable circular silhouette. It is ISO-compliant for depths up to 300 meters and features a professional-grade design that prioritizes structural integrity above all else. With its oversized components and high-visibility layout, it is a dedicated tool watch built to be worn over a thick wetsuit in the most challenging maritime conditions.
Technical Specifications
Case Size: 48mm (Oversized, heavy-duty professional profile)
Case Material: Silver-Tone Stainless Steel
Movement: Eco-Drive (Caliber B873; high-torque light-powered movement specifically designed to drive large, heavy professional handsets)
Crystal Type: 6mm Non-Reflective Curved Mineral Crystal (Extra-thick glass designed to withstand immense underwater pressure)
Water Resistance: 300 Meters (30 ATM / 999 feet) — ISO Compliant for Mixed Gas Diving
Dial: Black dial with extra-large, high-contrast luminous indices and a date window at 3 o'clock
Bezel: Unidirectional rotating elapsed-time bezel with a deep-grooved "gear" edge for operation with thick neoprene gloves
Strap: Integrated heavy-duty black polyurethane strap with a stainless steel buckle and an included wetsuit extender
Special Features
Helium-Safe Construction: Designed to be used in saturation diving environments without the need for a dedicated escape valve, thanks to its specialized hermetic sealing.
Oversized "Pro" Handset: Features a massive, high-visibility orange minute hand, allowing divers to track elapsed time instantly even in turbid or low-light waters.
Screw-Down Security: Includes a reinforced screw-down crown located at the 9 o'clock position (Left-hand drive) to prevent the crown from digging into the wrist and to provide extra protection against accidental impact.
Legendary Lume: Equipped with Citizen's highest-grade luminous material on the hands and markers, providing a long-lasting, brilliant blue/green glow for deep-sea legibility.
Integrated Lugless Design: The strap is bolted directly into the underside of the case, a structural choice that ensures the watch remains securely attached under high-stress conditions.
Reinforced Case Back: Features a heavy-duty screw-lock case back with the Promaster Eco-Drive insignia, contributing to its 300m depth rating.
