Keeping to tradition, Chopard always issues the first regular model of a new L.U.C movement in rose gold. (Special Editions are a different matter)
Usually, platinum is next and followed by white gold. There are not enough L.U.C movements to encase in steel nowadays.
Thus, it was unusual and we were highly honoured that the L.U.C 1963 Chrono PuristS Edition was in steel case, albeit issued one SECOND after the rose gold version!
The date display was mandatory for two traditions: the original L.U.C 1860 had a seconds display at 6 o'clock and it is uncommon to have an extra flat watch WITH a date display.
