Frederique Constant Slimline Heart Beat Automatic – Silver Dial – Stainless Steel Case 40 mm [FC-312S4S6]

Refined minimalism meets mechanical grace in the Frederique Constant Slimline Heart Beat Automatic FC-312S4S6, a slim, elegant timepiece engineered for those who appreciate understated sophistication. Encased in a polished 40 mm stainless-steel shell, its slender profile slides effortlessly under a shirt cuff — the ideal companion for business attire or formal wear. The silver sun-ray dial reflects light with subtle radiance, while the signature “Heart Beat” aperture positioned just below 12 o’clock reveals the beating balance wheel — a poetic window into the heart of Swiss automatic watchmaking.

Applied polished indices, slim hands and clean dial architecture allow the open-heart display to shine without distraction, offering a harmonious balance between classical restraint and horological transparency. Inside, the automatic movementprovides reliable timekeeping and a comfortable power reserve, while the exhibition case-back invites the wearer to admire the movement’s decorated rotor and finishing. The watch is completed with a high-quality black calf-leather strap, enhancing both comfort and elegance. Whether worn to an evening gala or daily office routine, the Slimline Heart Beat Automatic delivers timeless elegance and mechanical honesty in one graceful package.
