With a history that dates back to 1764, Arnold and Son makes some of the most stunning timepieces.To further underline their superb watchmaking prowess, we now have what is called the Arnold and Son UTTE. Available in 18k rose gold and paladium, it reveals the manual wound calibre A&S8200 from its sapphire caseback. This movement houses a 14mm tourbillon which including the case, measures only 8.34mm thick making the Arnold and Son UTTE one of the thinnest tourbillon watch in the market. Aptly named then as UTTE stands for "ultra-thin tourbillon escapement". Because of this, it wears comfortably despite its 42mm case diameter. Boasting of an 80 hour power reserve, it further indicates hours and minutes through a subdial above the tourbillon. While the rose gold Arnold and Son UTTE is more decorated and the paladium version a bit understated, both have an extremely beautiful finish.
