# Citizen Elegance Triple Calendar Moonphase Review by A.I. WatchMetrics

## Watch Summary
The Citizen Elegance Triple Calendar Moonphase (ref. AQ4100-00A) is a refined dress watch in the Japanese brand's upscale Elegance collection, showcasing a guilloche-textured white dial with applied Roman numerals, a detailed moonphase subdial at 6 o'clock, and practical day-date-month windows powered by the innovative Caliber 8760 Eco-Drive solar quartz movement offering up to 210 days of power reserve, perfect for the style-conscious professional desiring low-maintenance sophistication and 100m water resistance.

## Overall Watch Rating: 7.2/10.0

**Complications Metric (9.2/10.0)** - Packing triple calendar and moonphase into a thin quartz case rivals pricier offerings from Grand Seiko.
**Material Metric (9.2/10.0)** - Stainless steel with sapphire crystal and refined polishing matches entry-level luxury like Oris.
**Dials & Design Metric (8.8/10.0)** - The intricate guilloche dial and classic Roman layout benchmark classic European dress watches from Nomos.
**History & Innovation Metric (8.2/10.0)** - Eco-Drive solar tech and quartz legacy place it alongside Seiko's trailblazing contributions.
**Movement Metric (8.1/10.0)** - Solar quartz Cal. 8760 excels in accuracy and no-service reliability over entry mechanicals like ETA 2824.
**Versatility Metric (7.8/10.0)** - Formal appeal with solid WR transitions well from boardroom to evening, outpacing rigid dress pieces.
**Brand Metric (5.1/10.0)** - Solid mid-tier dependability akin to Hamilton, solid but shy of Tudor's luxury cachet.
**Functions Metric (5.0/10.0)** - Core time plus calendars and moon deliver average utility comparable to basic multifunction quartz.
**Rarity Metric (3.8/10.0)** - Mass production mirrors ubiquitous models like Omega Seamaster equivalents.

## Total Performance Score (TPS): 4.1

## WM Collector Grade: C
