Hi Edwin,
The current model of Tourbillon from Journe is the
dead seconds and is available in 38 or 40mm case in
platinum or rose gold.White gold(silvery grey colour)
or rose gold dial available with both cases.
The original tourbillon with rementoir partly visible on
the dial is only available in 38mm in plat or rg with yellow,
white or r gold dial.This model is discontinued but there may
be some still available at authorised dealers.
Can any of the purists experts please correct me if I have any
details wrong.
