Only three examples of this derived version of Model 25654 are documented in the production records. The first and only one in yellow gold was launched in 1989. It was not until five years later that the next two models appeared in platinum, ruby or sapphire. To this day, none of them have surfaced in the auction world, and there is only one drawing of this version with an emerald lacquered dial.
Sales from 1989 to 1994: a total of 3 units, of which: 1 in yellow gold (1989) and 2 in platinum (1994).
Derived from Model 25654 (1987).
