The Jaeger-Le Coultre Reverso watch is, quite simply, a design classic. With its patented reversible design and classic silhouette, this timepiece has been much admired but never equalled. With its Art Deco form, the concept and shape of the watch has changed very little since its inception in 1931, and this Jaeger-Le Coultre Grande Reverso Ultra Thin ladies watch stays true to the classic Reverso style. Presented in pink gold, accented by 30 bezel-set diamonds at the top and bottom, the reversible timepiece has hour and minute functions on a white guilloché dial, struck numerals and Bâton hands. Like many of the post-1980s Reversos, the Lady Ultra Thin Duetto Duo watch is a 'Duoface'. With one simple movement, a second dial (the verso), with a different personality and a different time zone, is revealed. Decorated with mother-of-pearl marquetry, this pearlescent dial has hour and minute functions, Dauphines hands and a single frosted numeral at 12 o'clock. The Duoface timepiece works on the principle of 'two dials, one movement': the self-winding Swiss-made Calibre 864A. Water resistant to 30m, the slim-profile Jaeger-LeCoultre Grande Reverso Lady Ultra Thin Duetto Duo watch measures just 9.3mm deep and is presented on an alligator leather strap with a double folding buckle.
