I used to worry about this a lot but I have learnt that only a miniscule fraction of people pay attention to watches at all and if they do they are not unlikely to also be enthusiasts and appreciate them for what they are. I work in academic medicine and very few people have any clue what I have on my wrist and even fewer care. I don't have any watches that fit your definition of flashy however, although I do have some that are expensive out of proportion to what would be expected from my line of work.
