A striking example of the jeweller’s art is this Longines evening watch with bracelet frame and case in 18 carat white gold. The blue dial nestles in a double frame of 21 diamonds and 27 navette sapphires. 186 brilliant-cut diamonds and 25 round sapphires gleam along the intertwined strands of the bracelet. These precious stones together weigh 26.07 carats. (LONGINES)
