The Frederique Constant Slimline Moonphase Ladies Watch (model FC-206W1S6B) is an elegant Swiss-made timepiece from the Geneva-based watchmaker's celebrated Slimline collection. Founded in 1988, Frederique Constant is recognized for blending traditional Swiss craftsmanship with accessible luxury, and this model exemplifies that balance with its refined moonphase complication and understated aesthetic.

The watch features a 36 mm stainless steel case with an ultra-slim 8 mm profile, protected by an anti-reflective sapphire crystal for exceptional legibility and scratch resistance. Powered by the Swiss quartz FC-206 caliber, the silver-white dial displays hours, minutes, seconds, and a classic moonphase indication. The fixed bezel and clean dial design give the piece a timeless, versatile look suitable for both formal and everyday occasions.

A matching stainless steel bracelet measuring 12 mm in width secures with a fold-over clasp with push-button release for a secure and polished fit. The watch is water resistant to 30 meters (100 feet), making it suitable for daily wear. It carries Swiss Made certification and comes backed by Frederique Constant's international warranty.
