The Frederique Constant Classics Index Automatic (FC-303NB5B6) embodies the brand’s philosophy of making Swiss luxury watchmaking accessible while preserving timeless elegance. Designed with a refined yet contemporary presence, this model showcases a perfectly balanced aesthetic rooted in classic horology.
Housed in a 40mm stainless steel case, the watch features a deep black dial with applied index markers and luminous hands, ensuring excellent legibility in all lighting conditions. A discreet date window adds everyday practicality without disrupting the clean dial layout. The dial is protected by an anti-reflective sapphire crystal, offering exceptional scratch resistance and clarity.
Powering the watch is the Frederique Constant FC-303 automatic movement, a reliable Swiss-made caliber that harnesses the natural motion of the wearer’s wrist. With a 38-hour power reserve, this mechanical movement delivers consistent performance without the need for batteries.
Finished with a classic black leather strap and traditional buckle clasp, the Classics Index Automatic is a versatile timepiece—equally suited for business attire, formal occasions, or refined daily wear.
