Frédérique Constant Classics Slimline Heart Beat Automatic 40 mm Silver-Tone Dial Black Leather Strap [FC-312S4S6]

The Frédérique Constant Classics Slimline Heart Beat Automatic FC-312S4S6 distils the Maison’s signature open-balance display into an exceptionally elegant dress watch. Its hand-polished 40 mm stainless-steel case measures only 8.61 mm thick, framing a refined matte silver-tone dial with curved, applied stainless-steel indexes and hand-polished, stainless-steel-plated hands. At 12 o’clock, the signature Heart Beat aperture reveals the oscillating balance in motion, while an anti-reflective sapphire crystal provides lasting clarity and protection.

Inside, the slim FC-312 Swiss automatic calibre—based on the Sellita SW300—incorporates 25 jewels, operates at 28,800 vibrations per hour and provides approximately 42 hours of power reserve. A transparent exhibition caseback offers another view of the movement. Completed by a traditional black leather strap and fold-over clasp, this beautifully proportioned timepiece is an understated choice for business, formal occasions and refined everyday wear.
