It looks mostly original to me, but i am not an expert. looks like the crown is not original. Does anyone else have a thought on this watch. its at 3700 dollars now, a month or so ago a perfect mk 4 on C24 sold really fast for 9500 dollars. Anyhow would be interested what people think about the watch and what it might be worth. in the enicar book they list that there were 3200 mk3s and 2400 mk4s. So one would think that the mk4 might be worth more, but i honestly like the look of the mk3 alot better.
