Nice watch Plains........with regards to the hands, in the advert you have pictured they appear black (blued steel), even the sub second hand, could this just be because its not in colour maybe? They certainly look like the 'Modern; style rather than yours which are look like a diamond/cathedral hibrid. Also worth noting that in the advert the sub second hand has a small counter balance on the back unlike yours. In fact the whole sub second dial looks different, yours has marks ever 5 seconds, the advert just has a number 60 and 30. So either yours is a re-dial or Bulova changed design at some point
One thing I am intrigued with though is why yours has these hands, they certainly look right for this period of watch rather than the modern style, thats just my opinion though.
