The Frederique Constant Classics Index Automatic Men's Watch (Model FC-303NN5B6) is a Swiss-made timepiece from the Geneva-based luxury watchmaker. It features a 40mm polished stainless steel case with a thickness of 11mm, housing a striking navy blue dial with silver-tone and luminous indices as hour markers, matching alpha-style hands, and a date window positioned at 3 o'clock. The anti-reflective, scratch-resistant sapphire crystal protects the dial.

Powering the watch is the Caliber FC-303 Swiss Automatic movement featuring 26 jewels, a frequency of 28,800 vibrations per hour (4.0 Hz), and a 38-hour power reserve. The movement is visible through a solid caseback. An anti-shock system provides added durability. The watch is water-resistant to 50 meters (165 feet).

The navy blue leather strap features alligator embossing, a nubuck finish, and distinctive off-white stitching at 20mm width, secured with a standard signed buckle. This combination of the deep navy dial and coordinating leather strap creates a refined, versatile aesthetic suitable for both dress and casual wear.
