The Citizen NJ0170-83X is the fresh, modern color option of the NJ017 mechanical series, featuring an aqua blue / cyan dial that gives it a sporty, summer-ready look while keeping the design clean and wearable. The dial layout is simple and practical with luminous hands, luminous hour-dot markers, and a date display.
It’s powered by Citizen’s in-house automatic Caliber 8210, a proven and dependable movement that runs without batteries and winds from wrist motion. The watch is housed in a 43 mm stainless steel case and matched with a stainless steel bracelet for durability and everyday comfort.
Rated to 10 bar (100 m), it’s safe for daily wear and swimming. The crystal is crystal glass (mineral), keeping the watch aligned with its purpose: a rugged, affordable mechanical daily wearer with standout dial color.
