Jaeger Lecoultre Master Ultra Thin Perpetual Calendar White Gold Grey Dial. ( 2017 )
Unveiled in 2017, this version of the Master Ultra Thin Perpetual Calendar is quite eye catching with its grey dial and its white gold case.

Less cool or powerful than the steel black, it is actually more elegant and original.
The contrast with the blue sky of the moon phase is sublime, too.
Enjoy.
