CITIZEN ECO-DRIVE RADIO CONTROLLED WORLD CHRONOGRAPH (CALIBER H804): IDENTIFICATION
This is a modern Citizen Eco-Drive chronograph, likely reference AT8113-04H, featuring a rose gold-tone stainless steel case. The complex dial architecture utilizes applied rose-gilt indices and tracks multiple functions driven by the Caliber H804 movement. A 24-hour indicator sits at 9 o'clock, a 60-minute chronograph counter at 12 o'clock, and a dual-function subdial at 6 o'clock indicating the day of the week and 1/20th second chronograph measurements. The outer chapter ring displays 26 city abbreviations for the world time function, while the inner flange at 9 o'clock features radio signal reception indicators (NO, RX, OK). The watch is fitted with a 22mm brown leather strap.
PRODUCTION & REFERENCE HISTORY
COLLECTOR NOTES
Citizen's first radio-controlled watch, released in 1993, required a central antenna placed precisely in the middle of the dial, a design constraint entirely overcome in modern calibers like this one.

Confidence Factors
WATCHMAKER'S ASSESSMENT
Vintage Watchmaker & Horology Specialist
The dial layout uniquely identifies the movement as the Citizen H804, and the case/dial color combination matches known references from the AT811x series. The visual evidence strongly supports the identification without major ambiguities.
CONDITION & GRADE
Grading breakdown
Dial and hands are flawless. Case shows only minor surface scratches with no deep dings or plating loss. Strap has visible but acceptable wear.
Condition
The case exhibits superficial handling marks and light micro-scratches on the polished surfaces, consistent with careful use. The rose gold plating appears fully intact on the visible lug edges without significant rub-through. The 22mm leather strap shows mild creasing near the buckle holes but remains structurally sound. The caseback displays standard light scuffing.
