This variant features multiple cuts of diamonds that are set on the dial to make up the fan motif which extends past the dial and onto the lugs, case sides, and case. Overall, there are 689 diamonds on the 37mm watch. All the diamonds are set on 18k white gold. Each diamond is set by hand and requires hundreds of hours of craftsmanship to get right.
You’ll find on the 7 o’clock case side, a diamond-set fan-shaped charm that doubles as the activator for the minute repeater. When you pull this repeater, the watch will chime the hours, quarter hours, and the minutes past the quarter hour using two tiny hammers and a gong. The calibre used in this watch is apparently the world’s thinnest repeater movement.
