The DTE model combines Dual Time with two tourbillons. In the A&S8513 calibre, they are connected by a common motor organ, a pair of barrels providing a running time of 90 hours. These barrels then supply each of the separate gear trains, which each end in a tourbillon. These independent components indicate the hours and minutes and ensure an exceptional level of timekeeping.

The symmetry of the indications – an Arnold & Son signature – is particularly evident on this DTE model. The two time zones – local time in Roman numerals and reference time in Arabic numerals – are superimposed at 12 o’clock and 6 o’clock respectively. The tourbillons mirror each other at 3 o’clock and 9 o’clock and appear to float in mid-air thanks to their hand-chamfered 18-carat gold bridges. The mainplate on the dial side presents a vertical Côtes de Genève finish. To add to the balance of this timepiece, the crowns are positioned at 2 o’clock and 8 o’clock, allowing each time zone to be adjusted independently.
