Arnold & Son presented two new versions of its UTTE Tourbillon, part of the Instrument Collection which is characterised by dials with off-centred hours and minutes to allow for the display of other complications without one overlapping the other. In line with this design aesthetic, the tourbillon of the UTTE occupies the lower portion of the dial.
Also the movements have different finishes. The red gold watch houses a rhodium-treated calibre decorated with Côtes de Genève rayonnantes with a precious hand-engraved bridge. The movement of palladium UTTE version has a more contemporary touch with NAC grey treatment and straight Côtes de Genève pattern decoration.
The UTTE has a movement that is just 2.97 mm thick and a case thickness of only 8.34 mm, making the UTTE one of the thinnest tourbillon watches on the market. With a diameter of 14 mm, the tourbillon cage takes almost half of the movement space allowing one to fully admire the mechanism.
It's interesting to note that the flying tourbillon cage is not inset into the calibre, as it happens often, but instead rises out of the movement achieving the same height as the hour and minute hands.
Two barrels delivers a power reserve of at least 90 hours, which is a remarkable result for an ultra-thin tourbillon.
Retail prices in Switzerland including taxes are 68,420 CHF for the red gold version (ref. 1UTAR.S02A.C120A) and 59,400 CHF for the palladium one (ref. 1UTAG.S04A.C121G).
