First developed in the '30s, Jaeger-LeCoultre's 'Reverso' watch allows the wearer to choose between two elegant faces depending on the occasion. This 'Classic Duetto' version has a slim 21mm rose gold case and fine alligator strap that make it perfect for those with slender wrists. Its silver-tone guilloché dial is detailed with contrasting baton hands and numerals, while the black sunray-brushed reverse is set with rows of sparkling diamonds that will gently catch the light during evening events and candlelit dinners.
