WWTC

Finally will be getting a worldtime chrono , have been looking at various models for the last years-RG,titanium,bracelet/straps/rubber.
Its thick and heavy(except the titanium).
Finally found the black&white dial titanium on strap.
This model is not seen in Asia's AD.Was it an Italian market model and how does titanium wears/look like say after 20 years?
thanks.
