Jumping Hours Burma Jade ANDERSEN Genève x Asprey

ANDERSEN GENÈVE X ASPREY
JUMPING HOURS BURMA JADE

Limited Edition of 12 exceptional timepieces

ANDERSEN Genève, the independent specialist in artisanal fine watchmaking, is proud to present the very final edition in its celebrated Jumping Hours series. The Jumping Hours Burma Jade is launched in collaboration with Asprey, the famous British luxury house. The official presentation will take place in Japan at Takashimaya Osaka Exhibition on 6th July 2025.

This exquisite limited edition of just 12 hand-made watches pairs ANDERSEN Genève’s masterful take on the jumping hours complication with one of the world’s most prized and enigmatic precious materials: the translucent, green beauty of Burmese jadeite.

It is the second collaboration between ANDERSEN Genève and Asprey, following the 2022 Heures du Monde worldtimer, once again exemplifying the commitment of both “Maisons” to the highest standards of artisanal horology and aesthetic craft. As before, the dial is double-signed with the logos of both brands.

ANDERSEN Genève introduced its contemporary Jumping Hours series in 2020, with a minimalist style showcasing exceptional dial craftsmanship. As the sixth and final edition, the Jumping Hours Burma Jade brings an artful close to this elegant line. All previous editions are now allocated.

JUMPING HOURS: AN ANDERSEVE GENÈVE SPECIALITY

In 2020, ANDERSEN Genève marked its 40th anniversary by introducing a new series of watches dedicated to the Jumping Hours complication. With its pared-back clarity and effortless style – featuring merely an hour window at 12 o’clock, and a minutes subdial at 6 o’clock – the Jumping Hours has become a key expression of ANDERSEN Genève’s distinctive voice in haute horlogerie: quietly radical, technically refined, and deeply rooted in traditional craft.

The complication itself holds a special place in the brand’s 45-year history. In 1995, founder Svend Andersen created his first Jumping Hours display as part of a minute repeater commission. This led to a series of important bespoke works and culminated in the invention of the double-ended “Jour & Nuit” display, an ANDERSEN Genève hallmark later adopted by Cartier for a beautiful ”Pasha Jour et Nuit” limited edition, made by Svend and his team in 1998, that is today much sought-after.

In 2020, the brand launched a new Jumping Hours model, based on the complication module designed by Svend. Its ultra-minimalist display has made it a canvas for specialist dial-making crafts, exploring rare materials and artisanal techniques.

Versions have appeared with dials in hand-guilloché precious metals or delicately cut from black jade and mother-of-pearl; a handful of unique versions have also been commissioned. As with all ANDERSEN Genève watches today, each has a precious metal case that is individually crafted using traditional techniques. Much in demand from connoisseur collectors around the world, the Jumping Hours line has received repeated nominations in the Artistic Crafts category at the Grand Prix d’Horlogerie de Genève (GPHG).

Now, the Jumping Hours Burma Jade draws this chapter to a close with a watch of extraordinary delicacy and presence. Created in partnership with the legendary House of Asprey, and limited to just 12 pieces, each one unique in its way, this is a scintillating demonstration of ANDERSEN Genève craftsmanship.

BURMA JADE DIAL: A STONE OF LEGEND

The centrepiece of the watch is its dial, fashioned from a single wafer of pure Burma Jade, known in the gem world as ‘Type A jadeite’ – unbleached, untreated, and extremely rare. Revered for its fine grain, high translucency and rich green tonality, Burma Jade has been prized for millennia as a symbol of harmony, renewal, and spiritual energy.

Cut to a thickness of just 0.40mm, the jade dial demands absolute precision in its preparation. At its thinnest point – where the jumping hour wheel is recessed – the dial measures just 0.25mm. Any flaw or inconsistency in the stone risks shattering during finishing, making the successful creation of each dial an exercise in nerve, patience and world-class skill.

From a distance, the dial presents a gently effervescent green. Closer inspection reveals the unique veins and fibres within the stone, making each dial subtly different and distinct. Upon this, the printed minutes chapter ring and brand logos are rendered in blue, creating a visual identity of poise, gracefulness and unmistakable beauty.

JUMPING HOURS: PURITY AND POISE

First used in the pocket watch era, the minimalistic clarity of the Jumping Hours complication has long been admired as one of the most elegant solutions to timekeeping, but one that requires significant technical dexterity.

In ANDERSEN Genève’s execution, the complication is built on an ultra-thin module created in-house and integrated with the ultra-slim Frédéric Piguet 11.50 calibre, a high-grade movement with dual barrels, generating a 70-hour power reserve. The Jumping Hours mechanism demands exceptionally fine tolerances and meticulous calibration to manage the sudden release of stored energy required for the precise, instantaneous jump at the top of each hour – a far more abrupt and forceful action than the continuous sweep of a traditional time display.

Moreover, to preserve the watch’s svelte proportions, the hour wheel is recessed into the underside of the dial, which is carefully hollowed out by hand to a thickness of just 0.25mm. This helps ensure an exceptionally slim profile of just 9.22mm in height, an essential aspect of the watch’s over-all elegance and integrity.

THE HAND-FINISHED CASE: AN ANDERSEN GENEVE HALLMARK

Each case is made from solid 950 platinum, entirely hand-finished and measuring 38mm in diameter. A variety of traditional machining and handcraft techniques are required to build the case and achieve its flawless finishes, including satin-brushed flanks and a mirror-polished bezel.

The curving, sculptural lugs are created separately and individually soldered, a rare technique that harks back to the golden age of watchmaking and one that distinguishes every ANDERSEN Genève case as a handmade object.

The case-back reveals the movement in all its beauty: hand-chamfered bridges, Geneva stripes, perlage, mirror-polished screwheads, and a rotor in hand-guilloché 18ct pink gold, finished in the classical “grains d’orge” pattern.

Surrounding the movement is a ring of 21ct BlueGold – an ANDERSEN Genève signature, formed by mixing gold with iron elements and heat-treating it to achieve unique tonalities. In this edition, a spectrum of purples, greys, and blues appears depending on the angle of light. The ring is hand-engraved with the dual signatures of the collaboration: ANDERSEN Genève & ASPREY, along with the individual number of the piece (X/12).

ASPREY – A LEGACY OF TASTE AND EXCELLENCE

Founded in London in 1781, Asprey has long been associated with connoisseurship, refinement and royal patronage. For over two centuries it has been the chosen house of monarchs, diplomats and aesthetes, admired for its craftsmanship across jewellery, leatherware, silver, and horological objects.

Asprey’s relationship with fine watchmaking stretches back to the 19th century. It played a pivotal role in introducing Patek Philippe to the UK and is famed for rare co-signed dials from the 1950s and ‘60s with makers such as Patek Philippe, Rolex and Jaeger-LeCoultre, which are now especially sought-after.

In 2022, this historic connection to horology found a new form with ANDERSEN Genève’s first collaboration with the English maison, the ANDERSEN Genève x Asprey Heures du Monde, a sumptuous worldtimer in red gold, limited to 24 co-signed pieces.

With the Jumping Hours Burma Jade, this collaboration continues, honouring the commitment of both brands to traditional craftsmanship and exquisite design.

ABOUT ANDERSEN GENÈVE

Founded in 1980 by master watchmaker Svend Andersen, ANDERSEN Genève has become one of the most exclusive Ateliers in Swiss watchmaking. A founding member of the Académie Horlogère des Créateurs Indépendants (AHCI) – an organization co-instigated by Svend – it is one of the few brands to specialise in bespoke haute horlogerie, working one-on-one with collectors around the world. It is known for its imaginative complications, refined worldtime watches and artistic craftsmanship, bringing a deeply artisanal approach to every creation. 

Since 2015, ANDERSEN Genève has been owned and directed by Pierre-Alexandre Aeschlimann, working in close collaboration with Svend Andersen (83 years old), Marco Poluzzi (83 years old), and a small, in-house team of talented watchmakers.

Operating from its original workshop overlooking the Rhône in the historic Saint Gervais area of Geneva – once home to the city’s famed cabinotiers watchmakers – and since 2022 with a second Atelier for case-making in La Chaux-de-Fonds, ANDERSEN Genève creates around 50 watches per year, each one a rare and lasting work of art. In fact, fewer than 1,400 timepieces have been manufactured since 1980.
