These three Longines designs, made specially for Montres et Bijoux Genève 1987, feature 18K gold cases with fluted middle. Left : a pair of extra-slim models with quartz movements, featuring flexible, wristhugging bracelets composed of polished gold links and diamond-pavé, sunray patterned dials. Right : a timepiece in the grand tradition, with openworked seifwinding movement. 64 diamonds are set into the bezel so as to follow its curvature - a technique mastered only by the most experienced jewellers.
