The painting

A daughter no one ever painted.

Florence, 1499. Lisa Gherardini, wife of the silk merchant Francesco del Giocondo, loses a daughter in infancy. Four years later Leonardo da Vinci begins her portrait, the painting the world knows as the Mona Lisa. The child appears in no painting, and almost nowhere in the record.

Five centuries on, Alex Righetto asked what she might have looked like had she lived, and what she would look like today. His answer is Mona Lisa’s Daughter, an oil on canvas of 150 by 120 centimetres. Her face is vivid, young and exact; elsewhere the figure breaks into patches of colour, as if suspended between presence and disappearance. The artist calls it a memento mori.

In April 2023 the painting appeared for a week on two monumental screens in Times Square, before some two and a half million passersby. It was exhibited during Art Basel Miami in December 2025 and has been featured by Vogue, GQ and Vanity Fair. The canvas is not for sale.

The artist

Alex Righetto

A Veronese painter, trained at the Academy of Fine Arts in Verona, Alex Righetto lives and works in the United States. His figurative language reinterprets the legacy of Italian and European painting with a contemporary hand: anatomical precision that dissolves into abstract brushwork, colour that carries both life and its absence. Each of his collections is built as a narrative, from a single question.

In 2024 he presented Romeo and Juliet: The Metamorphosis at Windsor Castle and at Palazzo della Gran Guardia in Verona, where more than 13,000 visitors came. His work has been shown at the Kaiserliche Hofburg in Innsbruck, in London, Milan, Florence, Cannes and Miami, and in 2026 at Art & Luxury Monaco. He belongs to the network of artists of Tota Pulchra, the Rome association linked to the cultural sphere of the Holy See.

During my research I discovered that Lisa del Giocondo is believed to have lost a daughter. I wanted to give that child a voice.

Three Pièces Uniques

Three originals, one of one.

Case and bracelet are set entirely with baguette diamonds, in 18K yellow gold, 18K rose gold and platinum. Alex Righetto paints the dial and the micro rotor of each piece by hand, so that no two portraits are alike: three original works by the artist, each bearing his signature engraved on the case.

Each Pièce Unique is presented under a bell, in the Coffret Midwolda. Fifteen per cent of the price of each will be given to a charity, to be revealed in due time.

Pièces Uniques I, II and III in 18K yellow gold, 18K rose gold and platinum

Fifteen numbered pieces

The portrait in enamel.

Each numbered piece carries Mona Lisa’s Daughter on an enamel dial, with a micro rotor painted by hand by Alex Righetto and his signature engraved on the case. Five pieces are made in each of 18K rose, yellow and white gold, each numbered within its gold, and every piece is delivered on an 18K gold bracelet with a quick change mechanism, together with a leather strap.

Five per cent of the proceeds of the numbered pieces will be given to Tota Pulchra in Rome, the association that brings artists together within the cultural sphere of the Holy See.

The case back of a numbered piece: Calibre VBA01, the hammer, the gong and the micro rotor painted by Alex Righetto

She appears twice.

Once on the dial, and once more on the case back, painted by hand on the 18K gold micro rotor of Calibre VBA01, where she turns with every movement of the wrist beside the hammer that strikes the hour. Twice each hour the hammer falls: the largest hammer ever set in a wristwatch, carried by a movement only 2.5 mm high.

Height: 2.5 mm
Frequency: 5 Hz
Rotor: 18K gold, painted
Strike: Twice each hour

The presentation of the Pièces Uniques

The bell is the box.

A Pièce Unique is not placed in a box; it is placed under a bell. The Coffret Midwolda is a real bell, cast in bell bronze and tuned to the note of the watch’s gong, resting on a plinth of Dutch bog oak joined as a ship’s carpenter would join it. Lifted by its crown, the bell reveals the watch; struck with its hammer, it answers. The drawer holds a third portrait, a small oil on copper by Alex Righetto, for the collector alone.

The coffret travels in an oak sea chest, carried by rope beckets twisted in the blue, ivory and gold of the Van Bergen torse.
