Legendary Swiss watch brand Angelus made a comeback in 2015 by unveiling U10 Tourbillon Lumière. This mechanical marvel pays tribute to to some of the most influential and forward-thinking designers from the 60s and 70s, such as Dieter Rams and Achille Castiglioni. With its unique design and especially its vitrine-type construction, the U10 offers an extraordinary platform to showcase not only its oversized tourbillon, but also miniature works of wearable art. Angelus now presents an artistic line based on the U10 platform.
The first unique piece from this Angelus U10 art collection pays tribute to the old tradition of Mexican Calaveras. These are part of a very ancient tradition of memento mori. The Calaveras are mainly used in the Mexican celebration of the Day of the Dead (Día de los Muertos), where people remember and honor those who have passed on with calaveras, poems and other forms of symbolism. The U10 Tourbillon Calavera is a unique piece in stainless steel, which launches the Angelus U10 art collection.
On one hand the U10 Tourbillon Calavera is classic haute horlogerie. Its dead beat seconds complication – where the second hand advances in full steps of one second – derives from 18th-century pocket watches; 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 Calavera can equally be viewed as a paragon of cutting-edge, contemporary watchmaking.
The generously-proportioned – 62.75 mm x 38 mm x 15 mm – case, which took over two years to develop, features no fewer than seven sapphire crystals. All the crystals are bevelled, polished and subtly protrude from the case, creating expressive three-dimensionality.
Four of these crystals – including one wrapping 90° over the end of the case – surround the tourbillon, allowing unfettered views to the beating heart of the timepiece. The large windows also let light flood in and shine a spotlight on this mechanical centrepiece. The vitrine aspect of the tourbillon space is cleverly enhanced by light-absorbing, matte black PVD finish on the interior walls encasing the tourbillon.
The stainless steel used to make the case is BO-988 specific steel. This annealed steel is of a higher quality than the usual 316L steel found in timepiece cases because it contains fewer impurities, is less liable to corrode and is more biocompatible. Its finer grain size allows for a better standard of polishing and higher level of finish.
With its generous 16.25 mm diameter, the hand-polished tourbillon cage is crafted from weight-saving stainless steel, while titanium has been chosen for the tourbillon bridge due to its strength and shock-absorbing qualities. The flying tourbillon configuration does not need an upper supporting bridge and offers unimpeded views to the top of the regulator. The combination of nickel-silver, titanium and stainless steel in a watch movement is unique and especially the magenta lacquer for the bridge of the tourbillon cage.
A large diameter one-minute tourbillon requires significant energy, which is amply supplied by the dual main spring barrels. When fully wound, the Angelus A100 calibre provides 90 hours of optimal power. The two mainspring barrels are optimally sized in a special ratio for a flatter torque curve, which maximizes accuracy throughout for the full 90 hours.
While the dead beat seconds hand’s step-by-step motion is the result of a traditional horological complication, the stepped seconds is also reminiscent of quartz watches. Completing the indications on the side of the case is the intuitive linear power reserve featuring a rhodium-treated hand filled with blue lacquer.
