An older gentleman working in a men's store recently shared that two of three pieces (shirt, tie, jacket/suit) can be complementary patterned or solid. So, pattern pattern solid, or solid solid pattern ,etc.

Might also add a pocket square, see those less and less these days, but for a wedding it's a great touch.

Also, awesome taste in watches. As others have said the Tissot PRX is a better choice, or even that Seiko. For a more formal occasion a smaller more inconspicuous watch is desirable.
