Silver-tone stainless steel case paired with a black leather strap. Features a patterned bezel made of stainless steel and a black dial marked with index and Arabic numerals for hours, plus minute markers around the outer rim. Analog-digital display type combines traditional hands with digital readouts. Includes luminescent coating on both hands and markers for enhanced visibility in low light conditions. Equipped with perpetual calendar functionality, accurately tracking dates until manually changed or encountering a leap year transition. Chronograph functions feature four sub-dials showing charge indicator status related to the solar-powered Eco-Drive mechanism; dual time zone capability allowing simultaneous display of two different cities' times typically via an analog GMT hand plus possibly digital indicators depending on layout configuration details from Citizen Caliber specifications; 24-hour elapsed timer dial for tracking durations during chronograph operation sessions lasting up to approximately seven days before requiring recharging. Powered by the Citizen Caliber Eco-Drive U680 movement, which harnesses light energy including sunlight and artificial illumination through its scratch-resistant sapphire crystal glass front to maintain accurate timekeeping without battery replacements unless component failures occur necessitating service center visits according to standard watch maintenance protocols involving disassembly only under authorized warranty conditions. Solid case back provides potential access for inspection though typically not user-serviceable by standard consumers due to specialized tools required per Citizen technical bulletins versus casual observation suitable for basic checks. Round case shape measures 46 mm in diameter offering a sporty profile with slightly larger dimensions proportionally balanced especially considering its intended use as reliable timekeeping during activities like diving or hiking where readability under various angles is crucial even when wearing multiple accessories simultaneously such as belts or pockets affecting wrist circumference dynamically throughout daily tasks; band width of 22 mm ensures comfortable fit for typical adult wrists while maintaining strap stability during rapid movements involving chronograph functions potentially causing slight adjustments in perceived tension due to dynamic interactions between the buckle clasp mechanism and watch components under acceleration forces when initiating complex sequences like time zone changes through button presses requiring coordinated internal mechanisms within Citizen's Caliber Eco-Drive systems designed to handle such transitions smoothly without user intervention unless interface complexities arise from specific design choices inherent to certain models versus standard complications. Water resistant up to 200 meters / 660 feet depth level suitable for recreational diving excluding very deep technical dives based on ISO standards distinguishing between casual splash resistance and certified dive watch capabilities which typically require higher pressure testing methodologies unlike some competitors who might specify different depths but Citizen's Eco-Drive U680 movement is inherently designed for reliable underwater operation maintaining consistent performance even after exposure to moisture from sweat during intense physical activities triggering alarms via integrated chronograph complications when functions exceed preset durations significantly impacting user experience through immediate auditory feedback until manually silenced by the wearer unless emergency protocols override standard behavior patterns allowing temporary disabling of alerts for critical situation management.
