The Frédérique Constant Classics Ladies Automatic Double Heart Beat [FC-313MAD3B6B] brings together natural gemstone beauty, mechanical watchmaking and jewellery-inspired refinement in a beautifully proportioned 36 mm design.

Its defining feature is a richly coloured natural green malachite centre dial. Recognized for its flowing bands and organic variations, malachite ensures that every example possesses an individual character. No two stone sections will display precisely the same pattern, giving each watch a subtle sense of exclusivity.

Surrounding the malachite centre is a finely textured outer dial set with eleven applied diamond hour indexes totalling 0.0429 carat. At 6 o’clock, Frédérique Constant’s signature Double Heart Beat aperture reveals the regulating mechanism beneath the dial, creating a captivating connection between decorative design and traditional Swiss mechanics.

More than simply an elegant accessory, the FC-313MAD3B6B is powered by a substantial La Joux-Perret-based automatic movement offering an impressive 68-hour power reserve.

The Return of a Frédérique Constant Icon

Frédérique Constant introduced its first Heart Beat design as a way of allowing the owner to see the mechanical movement operating beneath the dial.

The Double Heart Beat develops that idea through two gracefully intertwined openings. Positioned at 6 o’clock, the aperture creates visual symmetry while revealing the constantly moving escapement of the FC-313 automatic calibre.

This latest interpretation arrives approximately two decades after the original Ladies Double Heart Beat and presents the signature design in a more contemporary form. The proportions are confident yet elegant, while the natural gemstone dial gives the watch a stronger and more distinctive personality.

Rather than hiding its mechanical character, the Double Heart Beat celebrates it.

The Natural Beauty of Green Malachite

Malachite gives the FC-313MAD3B6B a depth and individuality that cannot be reproduced by a conventional painted dial.

The stone is distinguished by flowing bands of deep and lighter green. These natural variations catch the light differently across the surface, allowing the watch to change subtly depending on its surroundings.

Because malachite is a naturally formed material, variations in colour, pattern and banding should be expected and appreciated. Each dial is effectively unique.

The vibrant green centre is framed by a stamped, grained outer section, producing a refined contrast between organic stone and traditional watchmaking decoration. Polished hands and eleven sparkling diamond indexes complete the composition without overpowering the malachite.

Eleven Diamond Hour Indexes

Eleven applied diamonds mark the hours around the dial, with the Double Heart Beat aperture occupying the 6 o’clock position.

Together, the diamonds have a total weight of 0.0429 carat. Their restrained proportions introduce light and brilliance while keeping the watch elegant enough for regular wear.

The result is a well-balanced design: more distinctive than a traditional dress watch, but considerably more refined than an overly embellished jewellery watch.

A New 68-Hour Automatic Movement

Inside the watch is the Swiss automatic FC-313 calibre, developed on a La Joux-Perret base.

Operating at 28,800 vibrations per hour and fitted with 24 jewels, the movement provides smooth performance and an extended power reserve of approximately 68 hours. When fully wound, the watch can therefore be set aside for much of a weekend and remain running when worn again.

This is a meaningful improvement over many conventional Swiss automatic movements that provide approximately 38 to 42 hours of reserve.

The open dial allows the owner to observe the movement’s regulating organ from the front, turning an important mechanical component into part of the watch’s visual identity.

Elegant 36 mm Proportions

The polished stainless steel case measures 36 mm in diameter and 10.51 mm in thickness.

These dimensions give the watch a noticeable wrist presence while preserving the refined proportions expected of the Classics collection. The round case, polished surfaces and slender bezel place the emphasis firmly on the malachite and diamond dial.

A convex anti-reflective sapphire crystal provides excellent scratch resistance and maintains clear visibility across the dial.

With 50 metres of water resistance, the watch is designed to accommodate normal everyday wear while remaining first and foremost a sophisticated Swiss luxury timepiece.

Seven-Link Stainless Steel Bracelet

A polished stainless steel seven-link bracelet gives the watch a fluid, jewellery-like appearance.

The smaller individual links allow the bracelet to articulate comfortably around the wrist while producing multiple reflective surfaces. A folding clasp with push buttons provides a secure and neatly integrated closure.

Frédérique Constant also includes an additional green crocodile-pattern leather strap. The quick-release system allows the wearer to change between the steel bracelet and leather strap without conventional watchmaking tools.

The bracelet creates a polished, jewellery-inspired presentation, while the green strap produces a more colourful and traditional dress-watch appearance.

A Distinctive Alternative to Conventional Diamond Watches

The FC-313MAD3B6B occupies an appealing position between traditional Swiss watchmaking and contemporary jewellery design.

Clients considering diamond-set models from the Longines PrimaLuna, Longines Master Collection, Cartier Ballon Bleu or TAG Heuer Carrera Date families may appreciate the Frédérique Constant for its natural malachite dial, visible mechanical escapement and extended 68-hour power reserve.

Where many comparable watches rely primarily on brand recognition or diamond decoration, the Double Heart Beat offers several points of distinction:

• A genuine natural stone dial
• A visible automatic movement
• Eleven applied diamond indexes
• A long 68-hour power reserve
• An interchangeable bracelet-and-strap system
• Swiss mechanical construction
• A comparatively accessible luxury price

These qualities make it especially compelling for someone seeking a recognizable Swiss luxury watch that does not resemble every other piece in the category.

Designed for Milestones and Everyday Luxury

With its combination of diamonds, natural malachite and mechanical watchmaking, the FC-313MAD3B6B is particularly appropriate for milestone occasions.

It can commemorate an anniversary, professional achievement, birthday or important personal event while remaining practical enough to enjoy regularly. The additional leather strap also allows its personality to change according to the occasion.

On the steel bracelet, it wears like an elegant piece of jewellery. On the green leather strap, it takes on a more traditional and expressive dress-watch character.

This versatility helps the Double Heart Beat move comfortably between professional settings, formal occasions and refined everyday wear.
