What color strap with my new Archimede Pilot Watch?

I have the Tangente Datum and because of its thin bezel look, the dial makes the watch looks deceivingly big (comparable to many 40 - 41 mm cases). I believe w/o the date you lose 2 mm or so (35.5) which is noticeable when compared side by side, but not so when you wear it.
As in probably all general cases, the white dial/black strap will make any watch look more formal. Light brown will always make it casual and go better with jeans and a t-shirt. Dark brown is a good compromise, imho
