I would have said original. I've never seen a redail with the nice 'silk lines' in the paint (don't know a better way to explain).
But, I'm no Monaco expert. Actually, I'm no expert in anything I guess ;-))

: Boy, now I'm getting confused. I ask the question if this Monaco
: 1533b dial was original or a re-dial and the verdict came back
: as a re-dial. I have since emailed the seller, a regular OTD
: contributor, and he asures me it is original and he doesn't mind
: taking it back as he wants to put it on hs next Monaco. I have
: read with interest the replies I got the other day but just want
: to be doubley sure you all reckon it's a re-dial before I send
: it back. Out of interest, where or who has a genuine, used but
: good condition or NOS 1533b dial as a comparison, and how much
: is one to buy if one is out there? My watch is beautiful but has
: a small piece of paint missing on the dial. Once again, many
: thanks chaps. David
