Frederique Constant Watch Classics Premier FC-301S3B5. A subtle combination of tradition and elegance, the Classics Premiere timepieces are housed in a delicate 38,50mm diameter case. On the dial, the applied indexes evolve around a mother of pearl, diamond setting or a colimacon decoration. Through the open caseback, which features a glassbox giving a magnifying glass effect on the back of the watch, one can admire the Cotes de Geneve enhancing the G100 La Joux Perret movement.
