# Longines 1832 Moon Phase Review by A.I. WatchMetrics

## Watch Summary
The Longines 1832 Moon Phase is an elegant dress watch in the Heritage Classic line, featuring a 40mm stainless steel case with polished and brushed finishes, a refined blue guilloche dial with applied indices and Arabic numeral at 12, a date window at 3 o'clock, and a detailed moonphase subdial at 6 o'clock powered by the in-house automatic Caliber L899 offering a 72-hour power reserve, perfect for the sophisticated professional or collector who appreciates 19th-century pocket watch aesthetics reimagined for modern wrists.

## Overall Watch Rating: 8.1/10.0

**Cohesiveness Metric (9.5/10.0)** - As a standalone heritage piece, its unified classic styling evokes the coherence of a Vacheron Constantin Patrimony without the ultra-high price tag.

**Dials & Design Metric (9.4/10.0)** - The intricate guilloche texture, blued dauphine hands, and poetic moonphase rival the dial artistry found on vintage Patek Philippe Calatravas.

**Material Metric (9.4/10.0)** - Stainless steel case paired with AR-coated sapphire crystal delivers the durable polish of an Omega De Ville at accessible luxury levels.

**History & Innovation Metric (8.7/10.0)** - Longines' 1832 founding legacy and aviation heritage provide established prestige comparable to early IWC pilot watches.

**Versatility Metric (8.7/10.0)** - Suited for formal occasions and casual elegance, it transitions like a Baume & Mercier Clifton but shines brightest suited up.

**Brand Metric (8.5/10.0)** - Longines offers renowned Swiss craftsmanship akin to entry Omega models with deep heritage appeal.

**Complications Metric (8.6/10.0)** - Date and accurate moonphase execution matches the reliability of Jaeger-LeCoultre Master Moonphases in a simpler package.

**Movement Metric (8.4/10.0)** - The L899's 72-hour reserve and smooth 4Hz beat perform on par with upgraded ETA movements in Tudor Black Bays.

**Rarity Metric (6.1/10.0)** - Common production volumes place it similarly to standard Rolex Oyster Perpetuals in availability.

**Functions Metric (4.0/10.0)** - Limited to time, date, and moonphase, it trails multifunction Grand Seiko Sport models in everyday utility.

## Total Performance Score (TPS): 4.3

## WM Collector Grade: C

## Performance Insights: Exceptional design, materials, and heritage shine brightly, but modest functions and rarity limit standout value against the $3,800 retail price.

## TPS Interpretation: Modest Value: The watch delivers refined elegance and strong build quality with classic complications at a price where more versatile tool watches compete effectively.
