HAUTLENCE HL SPHERE 02 Limited Edition

Reconnecting with its original identity by going back to basics, Swiss luxury watch brand HAUTLENCE continues to revolutionise the hour display by giving time a new dimension with the HL SPHERE 02, equipped with the eighth manufacture calibre of the brand. Following on from the jumping hour disc and the half-trailing hour chain, it now presents a jumping hour that spins on a sphere.

A blue sphere occupies the left-hand portion of the case, magnificently showcased by a sapphire crystal with a small dome, attracting everyone’s attention. It features twelve engraved numerals and rotates on itself through three rotation axes to reveal the current hour. This hypnotic dance, which initially appears totally random, actually follows a strict choreography, dictated by a conical differential including four conical gears that move around two crossed spindles inclined at an angle of 21 degrees. Two polished titanium cases featuring a blue PVD treatment adorn this tri-dimensional complex system to form a sphere.

To the right of the sphere is a retrograde minute display with a hand that travels along a fine and elegant minute track that opens onto the movement and partly reveals the balance. This aperture brings the gear train into view, which slows down the course of the minute hand when it returns to zero, regulating its speed so as to reduce impact forces.

The differential and snail used to trigger the jumping hour can also be seen beneath the minute hand. The minute track and the applied diamond-polished and metal blue minute numerals are fixed to an intermediary rose gold grained dial. The design of this dial adds a delicate vintage touch to the HL SPHERE 02, contrasting with the utterly contemporary look of this creation.

The white gold case of the HL SPHERE 02 adopts HAUTLENCE’s signature TV screen shape. With its balanced proportions, the HL SPHERE 02 model is compact and can be worn in any occasion, sitting perfectly on the wrist. An alligator-leather strap, in the same blue shade as the sphere, adds the final touch to the piece.

The HTL 501-1 hand-wound calibre beats at the heart of the HL SPHERE 02 model. Entirely developed, designed and produced by HAUTLENCE’s watchmakers, this movement is the perfect culmination of technical and aesthetic expertise.

The skeletonised balance bridge allows the owner to admire the oscillations of the proprietary balance spring produced by Precision Engineering AG, HAUTLENCE’s sister company. The equally skeletonised drum and ratchet reveal the barrel spring, thereby providing a simple yet ingenious visual indication of the power reserve.
