Arnold & Son Ultrathin Tourbillon Dragon & Phoenix "Eudialyte"

Ultrathin Tourbillon echoes Arnold & Son's uncompromising watchmaking excellence with its unequivocally timeless look and its ultra-thin tourbillon. When introduced in 2013, it was the thinnest tourbillon in the market, and today, it is one of the most recognisable and popular watches by the maison. The timepieces within the collection thrive on elegance, and that's not limited to the design. The in-house calibre is a sophisticated piece of machinery; it is only 2.97mm thick and houses a one-minute flying tourbillon.

Design And Aesthetics

The Arnold & Son Ultrathin Tourbillon collection seamlessly combines pizzaz with understatement. It carries a classic round slim case where clean lines and elegant curves rule the roost. The watches get their extra character from the dials, which have been a canvas for aesthetical experimentation. Since the debut model, the decoration and finishing on the dial have served as the lodestone. Hours and minutes are to be read from the sub-dial at 12 o'clock, while the perspicacious tourbillon escapement gets the pride of place at six. The rest of the dial design is sparse and has been well-utilised by the brand to flaunt its exceptional craftsmanship.

Movement

Arnold & Son owns a treasure trove of impressive movements. The Ultrathin Tourbillon collection is primarily powered by the manual-winding calibre A&S8200, which promises a power reserve of 90 hours. Arnold & Son later updated this in-house movement to create a calibre A&S8300 that offers a running autonomy of a whopping 100 hours. The line-up also houses a skeletonised version driven by calibre A&S8220.
