There was a very limited edition in titanium without a date. I think it was inspired by an Italian fashion designer or something: there were initials on the dial but I do not remember which ones GL or GW something like that.
Probably 40 pieces or so (a real limited edition). Unfortunately, I cannot find any picture
There is also the Mellow Yellow in titanium which was similar, but which kept the date
It came with a Saab freebie included
