Frédérique Constant Classics Heart Beat Automatic FC-310MC5B6 – Silver Dial, 40 mm Stainless Steel

The Frédérique Constant Classics Heart Beat Automatic FC-310MC5B6 embodies the essence of Swiss horology — combining classical design with visible mechanical artistry. Its refined 40 mm stainless-steel case houses a silver dial decorated with an intricate Clous de Paris guilloché pattern and a signature open-heart aperture at 12 o’clock, allowing a glimpse of the movement’s oscillating balance wheel.

Powered by the automatic calibre FC-310, this timepiece offers smooth self-winding precision and a 38-hour power reserve. The Roman numeral hour markers and Breguet-style hands enhance its old-world charm, while the sapphire crystal and exhibition case-back highlight its craftsmanship.

Paired with a black leather strap, the FC-310MC5B6 strikes the perfect balance between timeless sophistication and contemporary refinement — a hallmark of the Classics Heart Beat Automatic collection.
