Swiss luxury watch and clock maker Jaeger-LeCoultre introduced a special London edition - the Grande Reverso Ultra Thin 1931 - to celebrate the recent opening of its flagship store in Britain.

Only a few lucky ones will get their hands on the exclusive tribute edition as only 26 pieces are available. Similar to its predecessors - the Rouge and Chocolat models - this special London edition features a classy dartmouth-green lacquered dial, and a finely-chiselled engraving of the Palace of Westminster with Big Ben on the caseback.

Some other high-quality timepieces on display at this year's Masterpiece London included the Master Grande Tradition Perpetual Calendar Skeletonised, the Reverso Duetto Classique Set, the iconic Calibre 101 and the new Grande Reverso 1931 Seconde Centrale.
