Jaeger-LeCoultre Grande Reverso Lady Ultra Thin Duetto Duo
The Grande Reverso Lady Ultra Thin Duetto Duo is a decorated ladies (Duetto) model featuring the ability to display the time in two time zones at once (Duo). First offered for sale in 2013, the Duetto Duo is part of the Grande Reverso Lady Ultra Thin line. The case measures 40 mm tall by 24 mm wide like other models in this range but is 8.9 mm thick due to the Cal. 864A hand winding movement.
The Grande Reverso Lady Ultra Thin Duetto Duo was produced in both stainless steel (Ref. Q3308421) and 18 karat pink gold (Ref. Q3302421).
The entire Reverso line was revised in 2016 and the Grande Reverso Lady Ultra Thin line was replaced by the Reverso Medium Duetto and Reverso One, Reverso One Duetto, and Reverso One Duetto Moon, though there is not yet a dual timezone "Duo" model as of 2019.
