The Slimline Moonphase Manufacture is born out of Frederique Constant’s passion for high-quality horology. The Frederique Constant FC-700 caliber series, originally developed and launched in the 2009 Maxime Manufacture collection, is proof that wonderful technological advances can be made and are still incredibly easy to use. Over the past years, our designers, engineers, technical team, and dedicated watchmakers have all worked together to develop the FC-700 caliber series. What started as a relatively basic caliber, has evolved. Today, the full range of features and complications of any timepiece using an FC-700-series caliber can be quite simply adjusted via the watch’s single crown.

# Frederique Constant Slimline Automatic Moonphase Review by A.I. WatchMetrics
## Watch Summary
The Frederique Constant Slimline Automatic Moonphase is a refined dress watch characterized by its slim 40mm stainless steel case, opaline silver dial with guilloché accents and a captivating moonphase display at 6 o'clock paired with a date window at 3, powered by the in-house FC-705 automatic movement offering a 38-hour power reserve, perfectly suited for the style-conscious professional who values understated Swiss elegance and horological poetry in formal or business settings.
## Overall Watch Rating: 7.6/10.0
**Brand Metric (7.9/10.0)** - Frederique Constant punches in the entry-level luxury tier with consistent Swiss quality and in-house ethos, on par with Oris or Baume & Mercier.
**Dials & Design Metric (8.9/10.0)** - The guilloché opaline dial, blued feuille hands, and slim profile deliver exceptional dress watch aesthetics rivaling pricier Nomos or Junghans models.
**Complications Metric (8.2/10.0)** - The precise moonphase and date complication adds refined sophistication comparable to mid-range offerings from Montblanc.
**Material Metric (8.4/10.0)** - Polished stainless steel case, sapphire crystal, and premium leather strap provide a luxurious tactile experience akin to Tudor dress watches.
**Versatility Metric (7.8/10.0)** - Excels in formal and semi-formal scenarios with moderate casual adaptability, much like a classic Longines Conquest.
**Movement Metric (7.6/10.0)** - The decorated FC-705 automatic with 26 jewels and 28,800 vph beats reliably like an upgraded ETA 2824 in a Glashütte Original.
**History & Innovation Metric (6.8/10.0)** - Backed by 35+ years of slim complication expertise, it stands solidly against modern innovators like Nomos Glashütte.
**Functions Metric (7.3/10.0)** - Time, date, and moonphase deliver practical elegance for daily wear, similar to basic perpetual calendar previews in entry luxury.
**Rarity Metric (6.1/10.0)** - Its $3,500 price yields moderate exclusivity on par with popular Omega Seamaster variants.
## Total Performance Score (TPS): 4.1
## WM Collector Grade: C+
## Performance Insights
Exceptional design and complications shine alongside strong materials, while history and functions lag slightly, yielding fair value versus an implied price of $60,200 for equivalent performance.
## TPS Interpretation: Fair Value: The watch provides reliable functionality with a unique aesthetic at its price.
