The new Double Balancier now gleams in 5N red gold with a black gold
and enamel dial. With this latest version, Robert Greubel and Stephen Forsey
emphasize Double Balancier’s dramatic heart. The dial-side theater is set with
a black gold dial, minute-circle numerals, hour markers and power reserve
in champlevé grand feu enamel functions. All this focuses attention on a
timekeeping duet of the two balance wheels connected by the constant differ-
ential. An indicator, fitted to the differential, executes one complete turn in
four minutes.
