Shopify Product Description
Citizen Promaster Eco-Drive GMT Diver 200M
Reference: BJ7111-86L
Built for travelers, divers, and everyday adventure, the Citizen Promaster GMT combines rugged dive-watch capability with the practicality of a true GMT display. Powered by Citizen’s legendary Eco-Drive solar technology, this watch never needs a battery replacement under normal use and delivers reliable quartz precision with tool-watch toughness.
The bold Pepsi-style 24-hour inner ring allows tracking of a second time zone, while the oversized lume-filled markers and aggressive bezel design give the watch a distinctly modern Promaster identity. With 200 meters of water resistance and a solid stainless steel bracelet, the BJ7111-86L is equally at home underwater, on the road, or as a daily sport watch.
This reference has become increasingly appreciated among collectors looking for unique Japanese tool watches outside the usual mainstream GMT offerings.

Heritage & Collector Notes
Citizen’s Promaster series has long been respected for producing serious professional-grade watches at realistic prices. While many collectors focus on mechanical GMTs, the BJ7111-86L offers something different: quartz-level accuracy, solar convenience, and true travel functionality in a rugged diver platform.
The angular case design, oversized markers, and bold bezel styling give this model a distinctly modern Japanese-industrial aesthetic that stands apart from traditional Swiss GMT divers. Among Eco-Drive enthusiasts, references like the BJ7111 have developed a loyal following due to their reliability and low-maintenance ownership experience.
