Blancpain Lady B
Petite. Spherical. Mechanical.
Celebrating the 70th anniversary of the Ladybird collection, Blancpain pays tribute to the 1956 Ladybird Bullet. This historic feminine timepiece was created by Blancpain, under the helm of CEO Betty Fiechter, the first woman to lead a Swiss watchmaking house. The Ladybird Bullet was a horological landmark featuring the world’s smallest round movement. Today’s Blancpain Lady B continues Blancpain’s mechanical miniaturization legacy.
Blancpain Lady B. An idea born in 1956
Blancpain Ladybird Lady B is not a reissue. It is the contemporary reinterpretation of a simple and radical idea born in 1956: to fit fine watchmaking into an object the size of a jewel. Faithful to the spirit of the Ladybird Bullet, it takes up its founding gesture without copying its lines. This vision guided the entire development of the watch. Its architecture was built around Blancpain's automatic caliber 615, whose technical specifications were embraced from the very beginning of the project. The spherical case, sapphire crystal, polished rehaut, integrated pass-through strap, and water resistance were all developed in parallel to accommodate the movement within an unprecedented volume. It resembles neither a traditional round watch nor a shaped watch. Its bracelet loop is integrated and passes directly through the case, with no lugs or visible attachment. Conceived in volume rather than surface, Ladybird Lady B is a mechanical bubble: a sculptural object to wear on the wrist.
B as in Bijou
Not simply a watch, nor simply a jewel. Like the Ladybird Bullet before it, Blancpain Lady B resists simple categorization. It is a watch. It is a jewel. It is a design object. And yet, beneath this apparent simplicity lies a conviction that has guided Blancpain since 1735: a watch must be, above all, a watch. Its value is felt in its restraint – expressed through a clean, unadorned case and a pristine dial that allow its pure proportions to shine. Blancpain Lady B reveals itself to the one who wears it and to those who know how to look. Beneath this apparent simplicity lies an in-house caliber decorated to the standards of fine watchmaking.
A watch conceived in volume:
2.9 cm3
Where the traditional watch is defined by its diameter, Blancpain Lady B is defined by its volume. 2.9 cubic centimeters. An unusual measurement in watchmaking,but perfectly suited to an object conceived in space rather than drawn on a plan. At 19 mm in diameter and 13.2 mm thick, it fits in the palm of your hand like a polished pebble. Its form naturally invites touch. Holding it in your palm is a sensory experience. Under your fingers, the oscillating mass comes into motion. A subtle vibration reminds you that a mechanical heart beats within.
The finishing of the tiniest details
Available in stainless steel as in 18K red gold, the case is entirely finished by hand. Polished, satin-finished, and micro-blasted surfaces are executed successively on an already-assembled watch, each area carefully protected before working on the next. Even the engravings are not entrusted to laser alone. They are machined with mechanical cutters to achieve the depth, sharpness, and finishing quality required by the Manufacture. Blancpain Lady B reminds us that in watchmaking, complexity does not reside solely in complications. It can also lie in the perfection of an object of just 2.9 cubic centimeters.
The heart of Blancpain Lady B
The Manufacture caliber 615 that powers Blancpain Lady B measures 15.70 mm in diameter and 3.90 mm thick. It comprises 180 components, 29 rubies, and a power reserve of 38 hours. It beats at 3 Hz, or 21,600 alternations per hour. Its plates are decorated with Côtes de Geneve. The geometry of the case back has been completely conceived to accommodate the specific trajectory of this rotor. Introduced in 1995, the Manufacture caliber 615 has undergone continuous refinement, benefiting from technical advancements such as the introduction of a silicon balance spring. Decades of evolution have established it as a proven movement, renowned for its reliability and robustness.
A watch worn like a jewel
Each Blancpain Lady B comes with a double-tour calf leather strap, available in a choice of seven colors: white, beige, mocha, burgundy, blue, coral or purple. Closed with a pin buckle, it wraps naturally around the wrist and transforms Blancpain Lady B into a true jewel. It complements a tailored suit, disappears under the cuff of a white shirt, dialogues with a collection of bracelets and rings, or speaks for itself. Blancpain Lady B is available in stainless steel and 18K red gold.
B as in Bubble-form
In the mid-1950s, the world looked toward the future with an almost naive confidence in progress. It was an era of technological optimism, soon extended by the Space Age, when science, innovation, and a fascination with the future profoundly transformed visual culture. Architecture, industrial design, automobiles, and fashion reinvented themselves. Straight lines gave way to organic forms. It was in this creative universe that the Ladybird Bullet was born. Blancpain Lady B now revives its spirit through its spherical case, heir to this biomorphic language of the 1950s.
R52/R55, The World's Smallest Round Movement
Blancpain's ambition behind the 1956 Ladybird Bullet was bold: not only to create the world's smallest round mechanical movement but one that would be robust. The result was a triumph, of miniaturization. With a diameter, of just 11.85 millimeters, the original Ladybird caliber thanks to two key innovations combined record breaking smallness with sturdiness. The first was the addition of a fifth wheel to the gear train. A conventional mechanical movement has four, from the barrel to the seconds wheel. Fiechter's solution was to add an additional one, controlling the force reaching the escapement and reducing the caliber's overall dimensions. The second was the inclusion of shock protection for the balance wheel—an element that most very small movements omitted, to their détriment in durability.
