Angelus has returned to the forefront of contemporary high-end watchmaking with the U10 Tourbillon Lumière, boasting a radically deconstructed movement.Four years in the making, the U10 Tourbillon Lumière not only upholds the Angelus tradition of creating extremely inventive timepieces boasting finely-finished, in-house movements with long power reserves, it is also a timepiece of glorious contrasts.

On one hand the U10 Tourbillon Lumière is classic haute horlogerie. Its dead beat seconds complication – where the second hand advances in full steps of one second – derives from 17th-century high-precision pendulum clocks; the movement bridges and plates are in traditional nickel-silver that is bevelled and polished; and the traditional 2.5Hz / 18,000 vph of the screwed balance with Breguet-overcoil is a throwback to some of Angelus’ early pocket watches.

And yet, the modernist display, innovative engineering and state-of-the-art materials and finishing ensure that the U10 Tourbillon Lumière can equally be viewed as a paragon of cutting-edge, contemporary watchmaking.

Powering the U10 Tourbillon Lumière is an innovative, finely finished, in-house calibre complete with oversized, one-minute flying tourbillon, which is offset from the movement. The assertive, sculpturally-shaped case – in special annealed steel – features seven sapphire crystals. Visible from five sides in its own sapphire crystal showcase, the circular ballet of the tourbillon is on full display.

The imaginatively engineered movement, visible also through the display back, pays homage to Angelus’ 19th-century origins as a premium movement maker. The inspiration for the name U10 Tourbillon Lumière derives from the light (lumière in French) streaming through the three-dimensional sapphire windows and illuminating the mesmerizing tourbillon.
