This is an absolute gem. And Montblanc have also sweated the details to make it right for the years to come - i.e. the parts in contact with the skin are bronze tinted titanium for allergy reasons on the one hand and to keep discolouration more sensible. Matching movement colour scheme to the case is also something one will not do at the Tudor price level but that is well within the reach here - showing MB did not just go for the easy buck.
I guess this will not be a beach beater with its limited WR, so verdigris is unlikely 
All in all I may well rescind my white metal watch preference in this case
