Chester Active WX
Overview
Chester Active WX, designed by CHESTER WATCH FACES, is a premium digital watch face engineered for smartwatches running Google Wear OS 5.0+ (API Level 34 and above), including devices such as the Samsung Galaxy Watch 7, Galaxy Watch Ultra, and Google Pixel Watch series. The watch face is structured for active users who require high-density meteorological forecasting, physical fitness telemetry, and immediate application access directly from their smartwatch display.
Chester Active WX is built using Samsung and Google’s declarative Watch Face Studio and conforms to the modern Watch Face Format (WFF). Unlike legacy Wear OS watch faces that executed standalone Java or Kotlin background runtime code—which often introduced CPU wake-locks, memory overhead, and battery drain—the Watch Face Format is a purely declarative XML specification. The Wear OS system server handles the parsing and graphical rendering of WFF faces directly, shifting execution to low-power co-processors and significantly improving battery longevity.
The defining functional capability of Chester Active WX is its integrated meteorological suite. The watch face provides real-time ambient temperature, daily minimum/maximum ranges, humidity percentages, and ultraviolet (UV) index measurements. Users can toggle the primary forecasting complication between an extended 4-day synoptic outlook and a granular 4-hour micro-forecast. And it offers 30 curated color themes.
Biometric and activity monitoring are tightly integrated into the layout. The lower section displays real-time heart rate readings, cumulative daily step counts, dynamic distance calculations (switchable between kilometers and miles), and battery status indicators. In addition, Chester Active WX includes a celestial moon phase indicator, an unread notification counter, and multiple interactive tap zones that launch system calendars, battery menus, or user-assigned applications. The Always-On Display (AOD) profile maintains essential time, date, and weather elements while heavily dimming non-essential pixels to prevent OLED burn-in and minimize battery drain.

Which smartwatch devices are officially compatible with Chester Active WX?
The watch face supports circular Wear OS smartwatches operating on API Level 34+ (Wear OS 5.0 and above), including the Samsung Galaxy Watch 7/Ultra and Google Pixel Watch 2/3.
Can the weather forecast display be switched between hourly and daily modes?
Yes. The watch face settings menu permits users to select between a 4-day daily forecast and a 4-hour hourly micro-forecast.
Why is Chester Active WX incompatible with rectangular smartwatches?
The graphical coordinate architecture and complication geometry are compiled specifically for circular smartwatch displays, causing visual clipping on square viewports.
How does the Watch Face Format (WFF) reduce smartwatch battery consumption?
WFF eliminates standalone background executable code, allowing the Wear OS operating system server to render the interface efficiently on low-power co-processors.
How are custom color palettes and complication tap zones configured?
Users customize the face by long-pressing the active watch screen, tapping "Customize," and swiping across the color palettes and complication mapping slots.
